why is there is no point in adding more generations when an allele has become fixed

Answers

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

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?

Answers

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.

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.

Answers

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.

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.

A student wants to know the effect a mutation might have on a species' survival. The change causes a rabbit to have mottled brown fur. The student runs a computer simulation for ten generations. What possible conclusions can you draw? Choose ALL that apply

Answers

Answer:

A) Evolution occurred because the allele frequency changed over time.

C) The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.

E) The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.

Explanation:

Based on the data, you can conclude:

Evolution occurred because the allele frequency changed over time.

The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.

The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.

The possible conclusions that can be drawn are

evolution that occurred due to the allele frequency.Rabbits with mottled brown fur have a selective advantage.The mutation had a positive effect.What is mutation?

The mutation is a change in the DNA sequence that results from the copying mistakes that tke place during the cell division and the exposure to the radiating agent, exposure to virus and chemicals also leads to the cases of gene mutation.
