I NEED HELP ASAP! Which of the following is true of variation?
Select one:
a.
It is necessary for natural selection.
b.
It exists in almost all populations.
c.
It is caused by mutations and sexual reproduction.
d.
All of the choices are correct.
Answer:
all of them are correct
Variations are essential for natural selection to occur. It exists in almost all populations. It is caused by mutations and erotic reproduction. Hence, all of the choices are correct.
What do you mean by Mutation?A Mutation may be defined as the sudden, stable, and inheritable changes in the genetic material of an organism.
Variations provide the favorable traits that induce natural selection. Variations are caused by mutations, gene flow, and erotic reproduction. It exists in all life forms present on the earth.
Sometimes, variations decide the relative fitness of an organism and thus natural selection occurred.
Therefore, the correct option for this question is D.

If you cross two heterozygous Yy pea plants, what proportion of the offspring will be the dominant color yellow?
Answers: 50%, 25%, 75%, 0%
Answer:
The possible genotypes are: YY, Yy, Yy, yy
The proportion of the offspring with the dominant color is 75%
The cross two heterozygous Yy pea plants, the proportion of the offspring will be the dominant color yellow is the possible genotypes are: YY, Yy, Yy, yy. The proportion of the offspring with the dominant color is 75%. Thus, option C is correct.
What are the cross between heterozygous?If you cross a heterozygous organism with another heterozygous organism, pair two Tt and Tt. Below is a punnet square to show the result:
T t
T TT Tt
t Tt tt
This actually means that you have two heterozygous recessive and one homogenous dominant and one homogenous recessive. Genetics has known as the study of the heredity as well as the variation of the inherited the characters and the genetic properties and the organism's feature and the characteristics. It has also known as the branch of biology that deals with the study of genetic variation, genes, and the heredity in the organisms.
Therefore, the cross two heterozygous Yy pea plants, the proportion of the offspring will be the dominant color yellow is the possible genotypes are: YY, Yy, Yy, yy. The proportion of the offspring with the dominant color is 75%. Thus, option C is correct.

Which kinds of light can the greenhouse
gases in the atmosphere absorb? Which kinds
pass right through?
Answer: That energy reaches Earth mainly in the form of visible, infrared, and ultraviolet light; most of that energy passes through the atmosphere to warm the surface. The Earth absorbs this energy from the Sun and reemits it in the form of invisible infrared light. This energy is trapped by the greenhouse effect.
Explanation:
How do sprinters receive enough energy to sprint?
Answer:
As the fastest way to get ATP for muscle contraction, the phosphagen system is the predominant energy system used for races lasting up to 10 seconds. The muscles of sprinters like Maurice Greene, who has run 100 meters in 9.79 seconds, are great at producing ATP via the phosphagen system.

Which process can produce new inheritable characteristics within a multicellular species?
Answer: Gene alterations in gametes
Explanation:
Which plant cells contain half the DNA from one parent plant
Answer:
pollen and ovule
Explanation:
Pollination happens when a pollen grain, which contains half the genetic material needed to produce a new seed, is transported to an ovule.
What are the genetic makeup of pollen and ovule?The megagametophyte is found in the ovule, whereas the pollen grain is the microgametophyte.
Pollen grains are male reproductive structures that give rise to sperms, whereas ovules are female reproductive structures that give rise to egg cells. This is the primary distinction between pollen grains and ovules.
A flower has more pollen grains than ovules so that the pollen has a better chance of reaching the ovules.
Where it will have a better chance of causing them to produce seeds, which will lead to the growth of additional plants.
The portion of a flower that contains the egg and which supplies the other half of the DNA needed for a viable seed to form.
Therefore, pollen and ovule plant cells contain half the DNA from one parent plant.

A. The IA and I alleles show sex linkage.
B. The IA allele is recessive to the IB allele.
C. The IA allele is dominant to the IP allele.
D. The 1A and I alleles show codominance.
Answer: The answer is D.) codominance.
According to the table IA and IB are showing codominance character. If a person has both IA and IB alleles and has blood group AB, hence option D is correct
What is a blood group?The blood group is determined by the gene which produces, surface antigens on the red blood cells and antibodies present in the plasma.
In the blood group having i gene does not produce any sugar, while the IA gene produces sugar which results in the A blood group having antibodies against another blood group which is anti-B, and a person having the IB gene produces blood group B and has antibodies anti-A.
If having both IA and IB, it shows codominance, and having blood group AB does not produce any antibodies, while ii produces O blood group and antibodies anti-B and anti-A.
Therefore, IA and IB, show codominance.

Evolution is sometimes a controversial topic. Write an essay (minimum 5 short paragraphs) including the following:
What is your opinion about evolution?
Do you think there should be a controversy?
Do you think alternatives to evolution should be taught in schools?
Why or why not?
"What is your opinion about evolution?"
Evolution is very controversial, I can agree. But in my opinion, evolution is the only explanation for why we have creatures and living things on this planet, makes more sense than some space guy making every single animal and plant in seven days, simply because no one on Earth has that power, and it's downright impossible. I, personally am an Atheist, so my opinion is going to be different than most people's opinions on the matter itself.
"Do you think there should be a controversy?"
Honestly, no. Christians and peoples of other religion get mad because a scientific fact meddled with their original opinion. Now, here's my opinion. It's ok not to accept change at first, that's an expected human reaction. But people, over time, accept change. But it's been 63 years since the theory was first published, and Christian society is still angry that a simple fact had ruined their entire ideology. I wouldn't say believing in God is simply a façade, but I will say that you should be accepting to other people's view of their own world.
Oh yeah, and although I refer evolution as a scientific fact even though the scientific community considers it a theory, is because we have direct evidence for this "theory", so what would be the point of calling it a theory.
"Do you think alternatives to evolution should be taught in schools?"
Depends if the school is more science-based or religiously-based. Until people can learn and accept the changes that have taken place in society, alternatives for evolution, like the Genesis chapter from "The Sacred Text", would probably have to be considered for Christian schooling. Meanwhile, more science centric schools can still teach evolution, even if Karen complains about it.
Well there's my essay. When I first started my account, I had asked two questions like this one. I honestly enjoyed writing my feelings, it's really rare when I get to find questions like these on Brainly. Thanks!

Insulin is a protein that maintains homeostasis in the amount of sugar in the blood. When there are high levels of sugar in the blood, cells in the pancreas generate more insulin and release it into the blood. This causes muscle cells and fat tissue to absorb sugar. When there are low levels of sugar in the blood, the production of insulin is slowed.
What is the most likely cause of the phenomenon described?
1. Glucose has a chemical reaction with blood cells to create insulin.
2. The expression of the insulin gene is regulated by blood glucose concentration.
3. Pancreas cells have more copies of the insulin gene than other cells.
4. The body has a surplus of insulin stored in the pancreas and releases it when needed.
Option B(2) :
The expression of the insulin gene is regulated by blood glucose concentration.
