Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

1. Consider the following food chain.
grass
deer
wolf
If the deer population increases, explain what could happen to the grass population
Most likely the grass population will decrease and the wolf population will increase.
Eventually it should level out again though.
If the population of deer will increase will result in the decrease in grass quantity.
What is a food chain?A food chain is a linear network of links in a food web that begins with producer organisms and ends with an predator, detritivores, or decomposer species.
A food chain also shows how organisms are related to one another through the food they consume. Each extent of a food chain represents a distinct trophic level.
Overgrazing occurs when there are too many deer in a given area, resulting in the loss of brush and shrubs in forested areas. The absence of undergrowth means that small animals and birds have no place to shelter and nest.
As a result, many native species are becoming extinct because they no longer have access to the habitat they require.
Thus, the grass population will decrease as a result of increase in deer population.

Why is the use of stem cells to produce new specialized cells, which can replace a body's damaged cells and cure disease, creating a controversy?
Answer:
human embryonic stem cells are obtained from embryos, thereby they are subject to ethical, religious, political and legal considerations
Explanation:
Human embryonic stem cells (HESCs) are pluripotent undifferentiated cells derived from blastocyst-stage embryos, which have the ability to produce any type of somatic cells. HESCs are obtained in vitro from embryos that are 5-6 days old. These cells are valuable tools in research in order to understand the genetic and physiological mechanisms of human development, as well as to develop treatments against diseases. The use of embryonic stem cells in research is controversial because these techniques involve the destruction of human embryos, and there are people who consider human life begins with the formation of the diploid zygote after fertilization, thereby raising the debate if a human embryo can be regarded as a human being.

The image shows a portion of the fossil record that spans several million years. In the image, the numbers designate different rock layers, with the number 1 corresponding to the oldest rock layer.
What statement provides the best explanation for the change in the species between rock layer 1 and rock layer 2?
A. An abrupt change in the environment caused the original species to evolve into several new species.
B. The original species hybridized with a single new species, resulting in a variety of species.
C. Humans introduced several new species into the environment after the original species had died out.
D. The original species died out, and several new species evolved that were better suited to the environment.
Answer:
answer is B
Explanation:
The original species died out, and several new species evolved that have desirable traits to survive in the changing environment. Therefore, the correct statement is option D.
What is theory of evolution?There are changes in species among different rock layers when the fossils are studied. Fossils are the preserved remains of living organisms from the past, and they provide information regarding different types of organisms lived during that particular period of time.
Scientists have found different fossils in different layers representing different groups of organisms. Various factors are responsible for these changes, including environmental changes, competition, genetic drift, etc.
Theory of evolution states that species evolve from time to time through natural selection, where individuals with desirable traits have high chances to survive. Therefore, the original species in rock layer 1 did not survive in the changing environmental conditions, and they died. However, new species evolved that were better suited to the new environment and have high chances of survival due to natural selection and adaptation.
Therefore, original species died, and new species evolved that were better suited to the environment.

Which statement accurately describes the relationship between air pressure, air density, or altitude?
As altitude increases, pressure increases.
As altitude increases, air density increases.
Air pressure and density are lowest at sea level.
Denser air exerts more pressure than less dense air.
The statement which accurately describes the relationship between air pressure, air density, or altitude is: D. Denser air exerts more pressure than less dense air.
What is air circulation?Air circulation can be defined as the movement and flow of atmospheric air from one point of the equator to another such as North pole to South pole, especially over long distances due to difference in atmospheric pressure.
Generally, atmospheric air that has more density (denser air) would exert more pressure than an atmospheric air that has less density because of a difference in temperature.
Read more on pressure here: https://brainly.com/question/24827501
The statement that describes the relationship between air pressure, air density, or altitude is "denser air exerts more pressure than less dense air," hence option D is correct.
What is air pressure, and air density?In contrast to the specific volume, which is described in terms of unit mass of dry air, air density is defined as the mass of air per unit volume.
Everything you touch is pressed upon by the weighty air that surrounds you. This pressure is referred to as air pressure or atmospheric pressure.
This is due to the fact that more air molecules are crammed into a given amount of air as density increases.
The force exerted by more air molecules to be greater, and as pressure is the force exerted per unit surface area, it follows that higher density air will experience greater pressure than air with lower density.
Therefore, option D is correct.

why is there is no point in adding more generations when an allele has become fixed
Answer:
Low genetic diversity, which is seen with allele fixation, is dangerous as it can lead to mass extinctions. If there is little genetic variability within a population and the genetically similar individuals all are susceptible to a certain pathogen, the population will likely cease to exist. This is why we see examples of populations with fixed alleles becoming threatened or endangered
Explanation:
basically, it will cause extinction
