Before United States citizens travel to Africa, a(n) _____ for yellow fever is required.
Answer:
Vaccine
Explanation:
I'm not sure but it seems like the most logical answer.
Answer:
The correct answer is immunization or vaccination.
Explanation:
Immunization is the method of developing immunity or resistant to a particular infectious disease, generally by shots or vaccines. Vaccines trigger the immune system of an individual to prevent the person against that infectious disease or pathogen.
The vaccine for yellow fever is the weakened form of the virus provided to the individual in a single shot. It can be given to people travel to yellow fever prone areas such as Africa.
Thus, the correct answer is immunization or vaccination.
This is when a seed will be produced that can turn into a genetically identical plant. Question 3 options: Pollinating by the wind Self-pollination Pollinating by bees Cross fertilization
Answer:
Apoximis or asexual seed formation
Apoximis is when a seed will be produced that can turn into a genetically identical plant.
Explanation;
Asexual reproduction is the type of production that results to offspring or organisms that are genetically identical to the parent plant. In plants, plants can reproduce asexually through vegetative reproduction or apomixis, without fertilization of gametes.
Apomixis is where some plants can produce seeds without fertilization. This occurs when an ovule or part of the ovary gives rise to a new seed.
Explain how carbon cycles between living and non living things
Answer:
it is burned by fossil fules (non-living parts) then the trees soak it up and plants then the animals eat it (living part).
Explanation:
The carbon cycle involves moving carbon among living and nonliving entities. It involves a biological cycle where carbon moves between plants and animals through photosynthesis, consumption, and respiration, and a slower biogeochemical cycle where carbon gets stored in various carbon reservoirs like atmosphere, oceans, soil, rocks, and earth's interior.
Explanation:The carbon cycle is a key part of our planet's biosphere that involves the movement of carbon among living and nonliving parts of the world. It's essentially divided into two interconnected sub-cycles: the biological carbon cycle and the biogeochemical carbon cycle.
In the biological carbon cycle, living organisms are deeply connected in this process. Carbon moves between autotrophs and heterotrophs via atmospheric carbon dioxide. Autotrophs use energy from the sun to convert carbon dioxide into glucose, a high-energy compound. This process also produces oxygen as a byproduct, which then enters the atmosphere. On the other hand, heterotrophs, including most animals, consume these high-energy compounds, releasing the carbon back into the atmosphere as carbon dioxide through respiration.
Next, in the biogeochemical carbon cycle, the movement of carbon through the land, water, and air is more complex and occurs much more slowly. Carbon is stored for long periods in carbon reservoirs such as the atmosphere, oceans, soil, rocks, and Earth's interior, creating a constant exchange of carbon among different components of the environment.

what is brood nurse
A brood nurse in biology is a member of a social insect colony responsible for the care of the young, having specific adaptations for tasks such as feeding, grooming, and protecting the larvae and pupae.
The term "brood nurse" refers to certain members of social insect colonies, such as ants, bees, and wasps, that are responsible for the care of the young, which is known as the brood. These nurse workers have specific physiological and behavioral adaptations that enable them to perform tasks such as feeding, grooming, and protecting the larvae and pupae. For instance, in honeybee colonies, nurse bees feed the larvae with a substance produced in their hypopharyngeal glands, known as royal jelly or worker jelly, depending on the larva's diet, which will determine its development into either a queen or worker bee.

YOUR WELCOME!!!!!!!!!!------honestly no one knows this c_r-a--p
Hello. This question is incomplete. The full question is:
"Which statement best describes a typical difference that could be found between the "Analysis" and "Conclusion" sections of a
lab report?
Only the "Conclusion" section describes errors that occurred during the experiment, and only the "Analysis" section suggests further research.
Only the "Analysis" section includes specific data comparisons, and only the "Conclusion" section suggests further research
Only the "Analysis" section discusses whether the original hypothesis was supported, and both sections include graphs of data.
Only the "Conclusion" section discusses whether the original hypothesis was supported, and both sections suggest further research."
Answer:
Only the Conclusion section discusses whether the original hypothesis was supported, and both sections suggest further research.
Explanation:
In a laboratory report, the session called "analysis" is responsible for reading the research data and showing how that reading was performed in relation to how the experiment was conducted. This analysis will generate results that will be interpreted in the section called "conclusion". At the conclusion of a laboratory report, the results of the analysis are discussed and a final conclusion of the experiment is stipulated, where it is discussed whether the hypothesis that was being investigated is deferred by the results of the exoerimento or not.
compare and contrast the two cycles of matter
Answer:
The two cycles of the matter are the carbon and nitrogen cycle. Both of them are biogeochemical cycles, it means that the chemicals spend a portion of the cycle in living things and non-living things. They are also common in that they both recycle nutrients that are essential to all organisms.
They are different in the manner that they cycle. Nitrogen is huge, 78% of the air around us is nitrogen. It cannot be used by plants or animals. Once the nitrogen is used by the plant and make its way to the animal, it can be released to decomposition.
Carbon has no requirement in processing by bacteria prior to plants and animals being able to use. Plants take carbon dioxide and make it sugar, animals eat the sugar. Some of it is released carbon dioxide that we exhale.
Answer:
The path of energy in an ecosystem is unidirectional, that is, it has a one-way path. On the other hand, matter circulates between the biotic environment and the abiotic environment, thanks to the presence of decomposers. This circulation of matter is called cycles of matter. These cycles are essential for the life and reproduction of living beings. They are natural processes that recycle chemical elements such as carbon, water, nitrogen, phosphorus, among other elements.
Below is a comparison between the carbon and nitrogen cycles.
Explanation:
Nitrogen: Nitrogen is an essential chemical element for life, it participates in protein molecules and also in the nitrogenous bases of nucleic acids. In its gaseous form (N2), it constitutes almost 80% of the atmospheric air, but it cannot be assimilated directly by the vast majority of living beings. Plants can absorb nitrogen in the form of ammonia or nitrates and animals take advantage of this element when they ingest proteins that contain it. Plants can obtain nitrates by two different methods: biological or direct fixation and nitrification.
Carbon: Organic compounds are those that have carbon in their composition. In the atmosphere, we find carbon in the form of carbon dioxide (CO2). Carbon dioxide is popularly known as carbon dioxide and it can pass from the abiotic medium to the biotic medium through the producers, through the process of photosynthesis. Photosynthesis uses six molecules of carbon dioxide to produce one molecule of glucose, so deforestation contributes to the accumulation of carbon dioxide in the atmosphere. Carbon can occupy different trophic levels along the food chains and returns to the abiotic environment through the breathing of living beings, in the form of CO2, and also through the decomposition of excreted substances and organisms that have died.
Burning fuels such as coal, firewood and petroleum products, such as gasoline, also releases carbon dioxide into the atmosphere. Some of the carbon does not return to the cycle, as it enters the composition of bones and shells, constituting the carbonates that decomposers are unable to modify. The assimilation and return of carbon to the abiotic environment are directly related to the energy flow of ecosystems. We can see from this that all cycles are related, to keep the biosphere in balance.

Compare and contrast DNA and RNA. After the comparison, describe the entire process of DNA replication. You must include all of the steps. (Ex. Transcription-Translation-and-Replication)
98 points and will give brainliest
Answer:
The steps of DNA replication always begin by separating a twisted strand into two untwisted molecular strands. It happens in the specific area of a chromosome known as the “origins". The origins contain a series of codes that attract the helicase, a protein that aids in the separation of the strands. Once the helicase locates the origins, it sends out signals inside the cell for other replication initiator proteins to help out in the separation. DNA strands are being separated by breaking the hydrogen bonds between the nucleotide base pairs, such as those of adenine (A) and thymine (T), and guanine (G) and cytosine (C).
Step 2: Replication Fork Formation
Splitting the original double helix into two strands visually presents a Y-shaped formation known as the replication fork. Each prong appears as an elongated line that requires an identical half to match in order to form a new pair of strands. One of the separated strands is called the leading strand, which is constantly utilized for DNA synthesis while the lagging strand is responsible for the complimentary strand’s synthesis.
Step 3: Binding of Bases to Each Strand
Both leading strand and lagging strand already has base patterns from the start and it serves as the template for the corresponding strands. For each strand, the bases match with the free floating nucleotides present inside the cell following the nucleotide base pairing rules to establish the hydrogen bonding between a separated strand and a new matching strand. It is made possible by the DNA polymerase, an enzyme that functions like a sewing machine in matching and zipping both strands together.
The replication process does not result to a brand new chain of DNA. It is always a mixture of both the original strand that is conserved as a partner all throughout the continuous steps of DNA replication process and the recently made strand. This process is recognized as the semiconservative replication.
Step 4: The Termination of the Replication Process
The termination process occurs as soon as the DNA polymerase enzyme arrived at the edge of the strands where no more possible replication could occur. But before the process is completed, it goes through the process of repair to correct errors such as mismatching of nucleotides. After this step, the DNA replication is completed.
Explanation:
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance.
Ribonucleic acid (RNA) is a polymeric molecule implicated in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with proteins and carbohydrates, constitute the three major macromolecules essential for all known forms of life

Is this individual male or female? How can you tell?
In biological terms, the sex of an individual is primarily determined by the X and Y chromosomes in mammals, with XX indicating a female and XY indicating a male. However, in some species, sex can change during one's lifetime. Gender identity can differ from biological sex, acknowledging the spectrum beyond male and female.
Explanation:The determination of whether an individual is male or female can largely be based on the X and Y chromosomes in mammals. Individuals homozygous for X (XX) are female and heterozygous individuals (XY) are male. The presence of a Y chromosome instigates the development of male traits and its absence results in female characteristics. This XY system is found in some insects and plants as well. However, it is important to remember that people often use the terms 'male' and 'female' to describe both our biological sex and our gender identity. For some, gender identity might be different from their biological sex or the sex they were assigned at birth. In these explanations, 'female' and 'male' refer strictly to biological sexes.
Furthermore, some species can change sex during their lifetime, alternating between male and female; this is known as protogyny (female first) or protandry (male first). Also, some creatures, such as certain types of snails, are hermaphrodites. When two individuals mate, they both can produce eggs, exhibiting characteristics of both sexes.

b
Nitrogen is released back into the environment.
c
Nitrates are converted into proteins.
d
Nitrates are reabsorbed by the animal.
Answer:
Nitrgen Cycle
Explanation:
Animal waste includes nitrogen that passes through the nitrogen cycle, these steps summarise into:
The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms.
Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb.
Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere.
OPTION B. Nitrogen excreted by animals is released back into the environment, where microorganisms convert it to ammonia and subsequently into nitrates, which plants can then use to make proteins. Thus, the excreted nitrogen rejoins the nitrogen cycle.
Explanation:When animals excrete nitrogen, it is primarily in the form of urea or uric acid. These nitrogenous wastes are then released back into the environment. Bacteria and other microorganisms in the environment can convert these into ammonia. Ammonia is then converted into other compounds, such as nitrates, which can be used by plants to make proteins. Hence, the nitrogen excreted by animals enters back into the nitrogen cycle.

Ben was studying the Irish Potato Famine and wanted to identify a critical factor for it. Which factor can Ben consider as critical for the Irish Potato Famine?
A.
too much rainfall
B.
too little rainfall
C.
lack of fertilization
D.
lack of genetic diversity in the potato plants
Answer:
D. lack of genetic diversity in the potato plants
Explanation:
The Irish Potato Famine occurred because of successive years of failed crops. The Irish became almost totally dependent on the potatoes as their primary food of source by the 18th century. This led to heavy dependence on this plant for the sheer survival of the population, which makes the population very vulnerable to famine, as the genetic diversity is too small, so a single disease can make enormous damage. That is exactly what happened, as the late blight managed to destroy the potato plants, leaving the country without its primary food source. The end result was large portion of the population dying because of starvation, lot of people were barely surviving, and lot of people migrated out of the country.
Final answer:
Ben should consider the lack of genetic diversity in Irish potato plants as the critical factor for the Irish Potato Famine, as this led to the susceptibility of the crop to potato blight, resulting in mass starvation and emigration.
Explanation:
The critical factor Ben can consider for the Irish Potato Famine is lack of genetic diversity in the potato plants. This lack of diversity made the single variety of potato grown in Ireland extremely susceptible to a disease known as potato blight, caused by the pathogen Phytophthora infestans. When the blight struck, it wiped out the entire potato crop, which was a staple food source for the Irish population at the time. The devastation led to mass starvation, with over one million deaths, and huge emigration, with nearly two million people leaving Ireland. This event highlights the significant risks associated with low crop diversity and the importance of breeding a variety of crops to maintain food security.
