Which factors were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection?
(1 point)
1. a change in the diet of human populations as they settled in colder climates
2. the clothing worn by humans in the early 8th century
3.the interaction of human populations with predators in colder climates
4.the impact of UV radiation on folate and Vitamin D levels in human populations
Answer: The answer is 4
Explanation:
Vitamin D controls your skin pigment. It's kind of like when someone has an iron deficiency they get bruises and they turn a whiter shade.
Hope I helped :)
The factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection are the impact of UV radiation on folate and Vitamin D levels in human populations.
Ultraviolet B radiation produces diet D in human skin. Ultraviolet radiation can, however, smash folate. Folate is critical for the speedy increase of cells, particularly at some point in which its deficiency can motivate neural tube defects. The human frame additionally has a mechanism to save you overproduction of vitamins.
What is UV radiation?Ultraviolet is a shape of electromagnetic radiation with a wavelength from 10 nm to four hundred nm, shorter than that of seen light, but longer than X-rays. UV radiation is found in sunlight and constitutes approximately 10% of the whole electromagnetic radiation output from the Sun.
Thus it is learned that the above answers are well-explained factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection bout.

Explanation:
A population of tree frogs living in the Amazon rainforest have two skin color phenotypes controlled by the same gene. Hozygous dominant and heterozygous individuals have green skin while hozygous recessive individuals have blue skin. In the first generation, analysis of the alleles for this gene shows that 70 alleles of this gene are green, and 130 alleles of this gene are blue in the population. In the second generation, 90 alleles are green and 110 alleles are blue. Finally, in the third generation, 120 alleles are green and only 80 are blue. Based on this data, which description best describes this population of tree frogs?(1 point)
A) The green skin color is being selected over blue skin color.
B) The frogs are randomly mating with each other.
C) The population size of frogs is very large.
D) There are no individuals migrating into or out of the population.
Answer:
A
Explanation: You can see that the green colored frogs were once lower than the blue and as time started progressing the green started getting a higher population over the blue, as the blue decreased.
For the frogs, the green skin color is being selected over blue skin color. This leads to the abundance of the skin color in the third generation.
What is natural selection?
Natural selection refers to a situation in which traits that enable organisms to better survive and adapt in their habitat tend to persist whiole other traits gradually disappear.
In this case, we can say that the green skin color is being selected over blue skin color.

A farmer often sprays a certain kind of insecticide, a chemical that kills insects, on his plants to prevent locust bugs from eating all of his corn crops. One day there was a random change in the sequence of DNA in a locust egg cell. When the egg cell hatched, the locust was resistant to the insecticide (it would not be killed by it). Since that locust could survive and reproduce, natural selection occurred until the entire population evolved to become resistant.
A) Identify the variation that existed in the insect population. _________________________________
B) Identify the process that created this variation. _________________________________
C) Explain why the variations in the insect population would be passed on to the next generation.
D) Is this locust population likely to survive, why or why not?
Answer:
as they were living in that environment they adopted it and were able to in it ; the population was able to survive because they adopted it

Answer:
The answer is C.
Explanation:
This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.
