Explanation:
Which of the following statements is an accurate combination of postulates 1 and 2 of natural selection?
Heritable variation exists for traits among individuals in a population.
Drug resistance exists among all individuals in a population.
Heritable variation does not exist among individuals in a population.
Environmental variation exists for traits among individuals in a population.
Answer:
Heritable variation exists for traits among individuals in a population.
Explanation:
According to Darwin's theory of evolution, natural selection is the main evolutionary mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).
Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
The correct statement combining postulates 1 and 2 of natural selection is that heritable variation exists for traits among individuals in a population. This genetic variance allows for certain traits, like drug resistance, to be selected for and become more common over generations.
The accurate combination of postulates 1 and 2 of natural selection is that heritable variation exists for traits among individuals in a population. Charles Darwin's theory of natural selection is based on the premise that there is genetic variance within species, and these variations are what allow natural selection to act. Because of heritable genetic differences, when the environment changes or when members of a population are exposed to factors such as drugs, those with favorable traits that provide an advantage in those conditions are more likely to survive and reproduce, passing those traits on to their offspring. This natural selection process eventually leads to these favorable traits becoming more common in the population over successive generations, while individuals without these traits are less likely to reproduce, decreasing those traits in the population. Drug resistance, for example, does not exist among all individuals but is a heritable trait found in some individuals that can be selected for in environments with antibiotics present.
A yeast cell that forms a bud is called the "mother cell." Why is there no mother cell after a paramecium divides?
Answer: A)
Explanation:
Who developed the hypothesis that cells only come from other cells?
Answer:
Rudolf virchow in 1855
Explanation:
He said omnis cellula - e - cellula.
Mean cells formed from pre existing cells.
Final answer:
Rudolf Virchow developed the hypothesis that cells only come from other cells, which later became a central part of cell theory. Although, it should be noted that Robert Remak had published similar findings earlier, leading to a controversy. This principle complements earlier work by Schwann and Schleiden about the cell as the basic unit for all life.
Explanation:
The hypothesis that cells only come from other cells was developed by the German doctor Rudolf Virchow in 1858. This concept, a central part of cell theory, was summarized by Virchow using the Latin phrase omnis cellula a cellula, which means "all cells arise from cells." However, it's important to note that Robert Remak, a Polish scientist, and Virchow's former colleague, had published similar findings in 1852 and Virchow's lack of acknowledgment led to controversy over the credit for this aspect of cell theory.
Before Virchow, Theodor Schwann and Matthias Jakob Schleiden had suggested, in the early 1800s, that cells were the basic building blocks of all living things, setting the stage for the later development of cell theory. Virchow's observation of cell division under the microscope led to the realization that living cells can only arise from pre-existing cells, effectively refuting the idea of spontaneous generation and contributing to what we now understand as the modern cell theory.
The Cell Theory is now a fundamental principle of biology asserting that all organisms are made up of cells, all life functions take place within cells, and every cell originates from another pre-existing cell through the process of cellular division.

GG=
A.Homozygous offspring with yellow pod color
B.Homozygous offspring with green pod color
C.heterozygous offspring with yellow pod color
gg=
A.Homozygous offspring with yellow pod color or
B.Homozygous offspring with green pod color
C.heterozygous offspring with yellow pod color
Answer:
GG= B. Homozygous offspring with green pod color
gg= A. Homozygous offspring with yellow pod color
Explanation:
According to the given information, the allele for the green pod color (G) is dominant over the allele for the yellow pod color (g). A genotype that has two identical alleles for a gene is called homozygous for the gene. On the other hand, the genotype that has one dominant and one recessive allele for a gene is heterozygous for the gene.
The genotype "GG" has two identical alleles for the gene of pod color. Hence, the offspring would be homozygous with green pods.
The genotype "gg" also has two identical alleles for pod color. But here, the alleles are recessive. Hence, the offspring would be homozygous with yellow pods.

A) prokaryotes use a different genetic code from that of eukaryotes
B) bacteria translate only mRNAs that have multiple messages
C) bacteria cannot remove eukaryotic introns
D) bacterial RNA polymerase cannot make RNA complementary to mammalian DNA
C) bacteria cannot remove eukaryotic introns
Answer:
C) bacteria cannot remove eukaryotic introns
Explanation:
Because of that, before inserting eukaryotic DNA in prokaryotic cell, it is required to process it.
Cloning of DNA is a process used in molecular biology to replicate DNA fragments of interest. Enzymes required for this process are restriction enzymes which cut both, DNA of interest and bacterial plasmid that is used as vector and DNA ligases which fragment into plasmid. Recombinant plasmid is inserted into bacteria via transformation.

How can blocked coronary arteries lead to a myocardial infarction?
Answer: Myocardial infarction is said to occur when the amount of circulated blood that get to certain part of the heart decreases or blood did not get to those areas at all. This usually lead to the destruction of the heart muscles. Another term for myocardial infarction is heart attack. Myocardial infarction usually occur as a result of blocked coronary arteries. Coronary arteries are the ones responsible for supplying blood to the heart muscles. These coronary arteries can become narrowed or blocked as a results of atherosclerosis. When the arteries are blocked, it becomes impossible to get oxygenated blood to the heart and this leads to myocardial infarction.
Which of the following is a product of cellular respiration?
A)energy
B)oxygen
C)light
D)lactic acid
B) oxygen
Respiration is defined as the movement of oxygen from the outside air to the cells within tissues
Cellular respiration produces carbon dioxide, water, and ATP through the breakdown of glucose in the presence of oxygen. Hence, the correct option is A.
During cellular respiration, glucose is oxidized to produce these products along with energy in the form of ATP.
Another important product of cellular respiration is the net total of 36 or 38 molecules of ATP that can be generated from one molecule of glucose under aerobic conditions.
Cellular respiration is a key process in cells where glucose is broken down in the presence of oxygen to produce energy in the form of ATP, carbon dioxide, and water.

Thus, secretion of the saliva by the salivary gland dissolves some the chewed food and facilitates its passage through the digestive tract.
1. A future offspring has just been conceived. When does it have the highest level of potency?
A. Pluripotency
B. Totipotency
C. Unipotency
D. Multipotency
Totipotent cells represent the stage where a future offspring has the highest level of potency, being able to differentiate into any cell type in an organism. option B) is the correct answer.
A future offspring that has just been conceived exhibits its highest level of potency at the stage known as totipotency. This stage refers to the ability of a single cell to develop into all the cell types of an organism, including both the somatic cells and the placenta.
Totipotent cells are present at the earliest stages of embryonic development, specifically in the fertilized egg itself and the first few cells that result from its division. As development progresses, cells become pluripotent, then multipotent, oligopotent, and eventually unipotent, reflecting a decrease in their potential to differentiate into different cell types.

Genetic inheritance is being studied in a certain species of plant in which orange flower color (O) is dominant to white (o) and round leaf shape (S) is dominant to oval (s). A true-breeding orange-flowered, round-leaved male plant (Plant A) is mated with a true-breeding white-flowered, oval-leaved female plant (Plant B) to produce dihybrid offspring plant (Plant C). Assuming normal Mendelian genetics and independent inheritance of these two traits, which gametes might be produced by Plant C?
Answer:
OS, Os, oS, os
Explanation:
To do this, first we need to determine what the genotype of the Plant C offspring is. Since the parents are both true bred, this means that their offspring will get one allele of each parent, of each trait.
Here's a Punnett to help you there
OOSS x ooss
os os os os
OS OoSs OoSs OoSs OoSs
OS OoSs OoSs OoSs OoSs
OS OoSs OoSs OoSs OoSs
OS OoSs OoSs OoSs OoSs
So Plant C would have a genotype of OoSs.
A good trick to determining the gametes of a dihybrid, is the FOIL method. Just like in math, F- first, O-outside, I- inside, and L-Last
Look at the attachment to see the FOIL method:
"The correct answer is that Plant C might produce the following gametes: OS, Os, oS, and os.
To understand why these are the possible gametes produced by Plant C, we need to consider the genetic makeup of both parent plants and how these traits are inherited according to Mendelian genetics.
Plant A, which is true-breeding for orange flowers and round leaves, has the genotype OOSS. Plant B, which is true-breeding for white flowers and oval leaves, has the genotype ooss.
When Plant A (OOSS) is crossed with Plant B (ooss), the dihybrid offspring Plant C will receive one allele from each parent for each trait. Since the traits are independently inherited, we can look at each trait separately.
For the flower color trait:
- Plant C will receive an O allele from Plant A and an o allele from Plant B, resulting in the genotype Oo for flower color.
For the leaf shape trait:
- Plant C will receive an S allele from Plant A and an s allele from Plant B, resulting in the genotype Ss for leaf shape.
Combining these two traits, Plant C will have the genotype OoSs.
During gamete formation (meiosis), Plant C will produce gametes that carry one allele from each gene pair. For the flower color gene, Plant C can produce gametes with either the O or the o allele. For the leaf shape gene, Plant C can produce gametes with either the S or the s allele.
Therefore, the possible combinations of gametes that Plant C might produce are:
- OS (carrying the dominant orange flower and round leaf alleles)
- Os (carrying the dominant orange flower and recessive oval leaf alleles)
- oS (carrying the recessive white flower and dominant round leaf alleles)
- os (carrying the recessive white flower and oval leaf alleles)
These gametes represent all the possible allele combinations that Plant C can pass on to its offspring, given its genotype of OoSs."

A small creek runs through a mature forest, keeping the soil around the creek damp all year. A variety of ferns and several flowering plants thrive in this shady, moist area. Along the higher ground above the creek, many species of flowering plants that need less water grow. If a farmer diverted the creek to water his fields, causing the creek to dry up, what would be the most likely long-term consequence for the ferns and angiosperms in the forest?
A. The ferns would outcompete the angiosperms in the forest since they can tolerate a wider range of moisture conditions than angiosperms.
B. The angiosperms and the ferns would not be affected since their thick, waxy cuticle coverings would protect them from drying out.
C. The angiosperms would outcompete the ferns since their sperm do not need moist conditions to get to their eggs as ferns do.
D. The ferns and angiosperms would begin to produce spores instead of seeds since the spores are better able to survive dry conditions.
Answer:
The answer is A
Explanation:
Because the fern can tolorate less water.
Answer:
C. The angiosperms would out-compete the ferns since their sperm do not need moist conditions to get to their eggs as ferns do.
Explanation:
Ferns release their ciliated sperms in water which swim and travel to the archegonia to reach the egg cell. However, angiosperms do not need water for reproduction. They use pollinating agents to mount the pollen on stigma. Hence, in the lower water supply to the creek would not allow reproduction of ferns and angiosperms would out-compete.

A measure of how commonly a particular allele occurs in a population is known as the
Answer:
allele frequency
Explanation:
Allele frequency describes how often an allele appears in a population. This measure is usually expressed in percentage. Allele frequency can describe the variation that exist within the population. It can be calculated as the number of alleles divided with the total number of gene copies in that population.
Change in allele frequencies over a certain short period of time is defined as microevolution. Mechanisms of evolution that can change allele frequencies through time are mutations, natural selection, genetic drift and gene flow (migrations).
Allele frequency is a term in genetic biology that represents how common a particular allele is within a certain population. It's calculated by dividing the number of occurrences of a specific allele by the total number of alleles in a population.
Explanation:A measure of how commonly a particular allele occurs in a population is known as the allele frequency. This term is fundamental in measures of genetic diversity within a population in the field of genetic biology. For instance, if an allele for blue eyes has a high frequency in a specific population, then blue eyes would be a common trait in that population.
The allele frequency is typically calculated by dividing the number of instances of a specific allele by the total number of all alleles for the same gene in the given population. It is expressed as a decimal or percentage.

F Flies have wing lengths ranging from very long to very short.
G Flies with long wings are less likely to survive.
H Flies with long wings can produce offspring with short wings.
J Flies with short wings prefer to mate with flies with long wings.
Answer:
H Flies with long wings can produce offspring with short wings.
Explanation:
For example, if we name the gene for the wings length with A, then the fruit flies with short wings have the genotype aa (recessive homozygous), while those with long wings can have either AA (dominant homozygous) or Aa (heterozygous) genotype. So, if two fruit flies with long wings and Aa genotype are crossed:
P: Aa x Aa

Which statements describe film badges? check all that apply. an amplifying device that indicates the presence of ionizing particles a device that permits determination of the concentration of radioisotopes in the body or other substance film sensitive to radiation that is removed and developed to measure exposure a device used for monitoring individual cumulative exposure to ionizing radiation?
Answer:
Explanation:
Film sensitive to radiation that is removed and developed to measure exposure
A device used for monitoring individual cumulative exposure to ionizing radiation
Film badges are used to monitor and measure individual exposure to ionizing radiation by showing levels of fogging on a film that indicates the amount of radiation exposure.
They contain film sensitive to radiation that fogs up when exposed, with the amount of fogging being proportional to the radiation level. Film badges are worn by individuals who may be exposed to radiation, and they are regularly developed and checked to measure the exposure. These badges include different absorbers to determine the type and amount of radiation penetration. While film badges are a simple detection method, they are not very sensitive to low levels of radiation. More sophisticated devices, such as those utilizing crystals, tend to be more sensitive and reliable.

Ellis-van Creveld syndrome is a recessive genetic disorder that includes the characteristics of short stature and extra fingers or toes. In the general population, this syndrome occurs in approximately 1 in 150,000 live births. In a particular isolated population, however, the incidence of this syndrome among live births is 1 in 500.Assume that both the isolated population and the general population are in Hardy-Weinberg equilibrium with respect to this syndrome. Which of the following best describes the difference between the frequency of the allele that causes the syndrome in the general population and the frequency of the allele in the isolated population?A. The frequency of the Ellis-van Creveld allele is 0.002 in the isolated population and 0.0000066 in the general population,which suggests that selection for this trait is occurring in both populations.B. The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, showing that the rate of genetic mutation is highest among individuals in the isolated population.C. The frequency of the Ellis-van Creveld allele is 0.002 in the isolated population and 0.0000066 in the general population, which demonstrates gametic incompatibility between the populations.D. The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, which suggests that genetic drift has occurred in the isolated population.
Answer:
D. The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, which suggests that genetic drift has occurred in the isolated population.
Explanation:
If we assume that one gene is involved in Ellis-van Creveld syndrome and we name that gene with A, then the genotype of the syndrome would be aa.
In population 1, the frequency of the syndrome is 1/150000=0.0000066(it is the frequency of the aa gentotype)
In population 2, the frequency of the syndrome is 1/500=0.002
According to Hardy-Weinberg equilibrium
p2+2pq+q2=1 (p2 is the frequency of the dominant homozygous, 2pq is the frequency of heterozygous and q2 is the frequency of the recessive homozygous).
q or the frequency of the Ellis-van Creveld allele in Population 1 is [tex]\sqrt{0.0000066}[/tex] =0.0026
q or the frequency of the Ellis-van Creveld allele in Population 2 is [tex]\sqrt{0.002}[/tex] = 0.0447
The study of genes is called genetics. According to Charles Darwin, the gradual changes in the species over the period of time are called evolution.
The correct answer to the question is option D that is The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, which suggests that genetic drift has occurred in the isolated population.
What is the hardy Weinberg rule?In population genetics, the Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.In population 1, the frequency of the syndrome is 1/150000=0.0000066(it is the frequency of the aa genotype)In population 2, the frequency of the syndrome is 1/500=0.002According to Hardy-Weinberg equilibrium
