How does photosynthesis interconnect to the big idea of the cell
Answer:
Photosynthesis traps free energy present in sunlight that, in turn, is used to produce carbohydrates from carbon dioxide. Cellular respiration and fermentation harvest free energy from sugars to produce free energy carriers, including ATP. The free energy available in sugars drives metabolic pathways in cells. Photosynthesis and respiration are interdependent processes.
Cells and organisms must exchange matter with the environment. For example, water and nutrients are used in the synthesis of new molecules; carbon moves from the environment to organisms where it is incorporated into carbohydrates, proteins, nucleic acids or fats; and oxygen is necessary for more efficient free energy use in cellular respiration. Differences in surface-to-volume ratios affect the capacity of a biological system to obtain resources and eliminate wastes. Programmed cell death (apoptosis) plays a role in normal development and differentiation (e.g. morphogenesis).
Explanation:
Autotrophic cells capture free energy through photosynthesis and chemosynthesis.
Chemosynthesis captures energy present in inorganic chemicals.
Membranes allow cells to create and maintain internal environments that differ from external environments. The structure of cell membranes results in selective permeability; the movement of molecules across them via osmosis, diffusion and active transport maintains dynamic homeostasis. In eukaryotes, internal membranes partition the cell into specialized regions that allow cell processes to operate with optimal efficiency. Each compartment or membrane-bound organelle enables localization of chemical reactions.
Organisms also have feedback mechanisms that maintain dynamic homeostasis by allowing them to respond to changes in their internal and external environments. Negative feedback loops maintain optimal internal environments, and positive feedback mechanisms amplify responses. Changes in a biological system’s environment, particularly the availability of resources, influence responses and activities, and organisms use various means to obtain nutrients and get rid of wastes. Homeostatic mechanisms across phyla reflect both continuity due to common ancestry and change due to evolution and natural selection; in plants and animals, defense mechanisms against disruptions of dynamic homeostasis have evolved. Additionally, the timing and coordination of developmental, physiological and behavioral events are regulated, increasing fitness of individuals and long-term survival of populations.

5. What structures were visible ONLY in the elodea cell?
In elodea cells, the unique structures typically visible include chloroplasts, a large vacuole, and a cell wall. These structures contribute to the plant cell's function and protection.
Explanation:In an elodea cell, which is a fresh water plant species commonly referred to as waterweed, the structures that are frequently visible only within this type of cell include chloroplasts, a vacuole, and a cell wall.
Chloroplasts are integral to the process of photosynthesis; they convert light energy into chemical energy and give plants their green color due to the pigment chlorophyll. The cell is enclosed within a cell wall, which acts as a protective barrier and supports cell shape.
Unique to plant cells, including elodea, this structure is notable for being generally thicker and tougher than the cell membrane found in animal cells. Elodea cells also typically possess a vacuole, which is larger in plant cells (compared to animal cells), acting as a storage center.

What is The Convention on Biological Diversity?The Convention on Biological Diversity is an international treaty that aims to conserve biodiversity, sustainably use its components, and ensure the fair and equitable sharing of benefits arising from the use of genetic resources.
However, a limitation of the convention is that it does not include bacteria, fungi, or protists in its definition of biodiversity. This is because these organisms are not always considered in the same way as plants and animals, which are more visible and easily studied.
Bacteria, fungi, and protists play crucial roles in ecosystems and contribute to biodiversity, but they are often overlooked or undervalued compared to other groups of organisms.
Therefore, the Convention on Biological Diversity has been criticized for not adequately addressing the conservation of these groups of organisms.
The other answer choices are incorrect. The Convention on Biological Diversity acknowledges the importance of biodiversity and aims to safeguard it, and there is no indication that it prohibits the use of seed banks.

A mother has one allele for dimples and one allele for no dimples. What is the
probability that she produces a gamete with the allele for dimples?
A mother with a heterozygous genotype for dimples (Dd) has a 50% chance of passing the allele for dimples to her gamete.
The question is asking about the probability that a mother who has one allele for dimples and one allele for no dimples will pass on the allele for dimples. In genetic terms, dimples can be a dominant trait, and we might represent the allele for dimples as 'D' and the allele for no dimples as 'd'. If a mother's genotype is Dd, which means she is heterozygous for the trait, she has a 50% chance of passing on the D allele and a 50% chance of passing on the d allele to any given gamete (egg cell).
What evidence is there for plate tectonics? *
X-rays of the Earth that scientists have taken
evidence from drilling into the Earth
satellite images that show the outlines of the plates
geologic events like earthquakes and volcanoes that happen at their boundaries
Answer: geologic events like earthquakes and volcanoes that happen at their boundaries
Explanation:
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed.
Evidence for plate tectonics includes satellite images of plate outlines, earthquakes and volcanoes at plate boundaries, drilling samples, topographical studies, and the concept of uniformitarianism to infer past tectonic activities.
Explanation:The evidence for plate tectonics comprises multiple observations and scientific data. Satellite images enable us to see the jigsaw-puzzle appearance of tectonic plates, confirming the outlines of the plates. Geologic events such as earthquakes and volcanoes that predominantly occur at plate boundaries offer strong evidence of plate movement. These natural phenomena correlate with fault lines and areas of tectonic stress where the Earth's crust is undergoing deformation. Additionally, drilling into the Earth and studying rock layers can provide direct physical evidence of past and present tectonic activity.
Geologists also use the concept of uniformitarianism to understand plate tectonic activity from the geologic past. They interpret ancient tectonic activity by observing ongoing processes and their impact on the landscape—including mountain building and the formation of rift valleys and ocean trenches. The study of topography and bathymetry also offers insights into the tectonic history of an area, with changes in elevation indicating past plate movements.
Overall, the interplay of these pieces of evidence supports the theory of plate tectonics, explaining the dynamic and continually changing nature of Earth's surface.
How are organisms classified into the 6 different kingdoms?
Explanation:
kingdom: Protista ,fungi,plantae animalia,eubacteria, archaebacteria
Organisms are classified into one of three domains and six kingdoms based on criteria such as morphology and genetics, further categorized into a hierarchical taxonomic structure. The phylogenetic relationships, influenced by rRNA sequences, inform the modern classification, which is subject to change with new scientific discoveries.
Organisms are classified into six kingdoms based on several criteria including body morphology, developmental pathways, molecular genetic machinery, and more recently, phylogenetic relationships. Each organism belongs to a domain—Bacteria, Archaea, or Eukarya—which is the most inclusive category.
Within these domains, organisms are further categorized into kingdoms: the Kingdom Bacteria, Kingdom Archaea, Kingdom Protista, Kingdom Plantae, Kingdom Fungi, and Kingdom Animalia.
The hierarchical system of classification further divides organisms into phyla, classes, orders, families, genera, and species. The three-domain classification system, based on ribosomal RNA sequences, is widely accepted as a method to demonstrate evolutionary relationships and was first proposed by Carl Woese in the 1970s.
As new information arises, organisms can be reclassified. This process is similar to organizing products in a store and ensures that the taxonomic system reflects current scientific understanding.

How is the cloning of genes different from the cloning of mammals
Answer: cloning genes is when you remove a particular gene from the DNA sequence using restriction enzymes. cloning animals is making another replica of the same animal.
Explanation: DNA microarrays are used to study interactions among genes in a genome.
Gene cloning in mammals is different from other organisms because of the mammal cloning is riskier and harder than others as it can cause health issues.
What is Gene cloning?
Gene cloning means the formation of exact same DNA copy or gene copies through the use of genetic engineering techniques. The DNA molecule is extracted from an organism and the gene is then copied and a clone of this gene is formed. Gene cloning is one of the methods which is used for the isolation and amplification of specific genes of the genetic material.
Mammal cloning is different from cloning of genes in other organisms as it is riskier and harder than other organisms because it takes multiple try and can also cause health issues if not inserted properly. Cloning a gene in other organisms such as bacteria is almost always functional and no problems occur with it. It is also easier to clone a gene in an organism then a whole mammal.

What is produced when sugar is digested in an animal cell
Answer:
Carbon Dioxide
Explanation:
Glycolysis is the first step where glucose is broken down into two molecules. This occurs in the cytoplasm of the cell. By the end of the process, a molecule of glucose is broken down to carbon dioxide.
Final answer:
Sucrose is hydrolyzed into glucose and fructose, while lactose is hydrolyzed into glucose and galactose by specific enzymes. Many adults have difficulties digesting unfermented dairy due to insufficient lactase production.
Explanation:
Sucrose (table sugar) is hydrolyzed into glucose and fructose by the enzyme sucrase. Lactose found in milk is hydrolyzed into glucose and galactose by the enzyme lactase. The majority of the adult population have problems digesting unfermented dairy because they cannot produce sufficient amounts of the enzyme lactase - a condition called lactose intolerance.

C)
multiple alleles
D)

What are the chances that a cross between a black chicken and white chicken will result in blue offspring?
What are the chances that a cross between a black chicken and white chicken will result in blue offspring?
The inheritance pattern where both black and white chicken alleles are expressed is A)codominance, resulting in 100% chance of blue or speckled offspring when crossing pure black and pure white chickens.
The inheritance pattern observed when a black chicken is mated with a white chicken and the offspring appear spotted black and white, which looks blue in color, is codominance. In codominance, both alleles in the heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive but a mixture of both parent phenotypes. In the case of Andalusian chickens, when a pure black chicken (BB) is crossed with a pure white chicken (WW), all the F1 offspring are heterozygous (BW) and display the blue, or speckled, phenotype.
The chances that a cross between a black chicken and a white chicken will result in blue offspring are 100%, given that both parents are homozygous for their respective coat colors. In this scenario, the offspring are all heterozygous, displaying the mixed phenotype.
