Answer:
Explanation:
Hair type is an interesting case of something called incomplete dominance. What this means is that with hair type, if you have one of each version of the gene, you get a mix of the two or wavy hair. So for hair type, CC gives curly, Cs gives wavy and ss gives straight hair. Back to your specific situation.
HELP ASAP- Which type of evidence for evolution do you think is more informative: fossil evidence or genetic evidence?
Answer:
I think genetic evidence is more effective because you never know if something crashed into the rock and made it look like a fossil. So, I think genetic evidence would be a better option.
Hope this helps!
Answer:
Both are equal because you can use fossil evidence to show what type of animals evolved but you can also use genetic evidence to show that evolution happened.
Hope this helps! This is just my opinion on the subject.

Limiting factors caused by
natural disaster tend to be
which of the following?
A. Density-balanced
B. Density-dependent
C. Density-independent
Answer:
C. Density-independent
Explanation:
Limiting factors caused by natural disasters that tend to be Density-dependent. Thus, the correct option for this question is B.
What are the Limiting factors?The Limiting factors may be defined as anything that significantly constrains a population's size and declines or stops it from growing. Some examples of limiting factors may include biotic, like food, mates, and competition with other organisms for resources.
According to the context of this question, density-dependent factors are those factors that vary with respect to the density of the population. These factors affect a higher proportion of individuals when population densities are higher.
And a lower proportion when population density is lower. Examples of these factors may include, food, competition, predation, competition, parasitism, accumulation of toxic waste, etc.
Therefore, limiting factors caused by natural disasters tend to be Density-dependent. Thus, the correct option for this question is B.

Natural selection in the tropical ecosystem favors ferns that are tolerant to shade, high wind velocity, frost, drought, etc.
What do you mean by Ecosystem?An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.
The tropical ecosystem consists of dry seasons driven by the tropical rain belt moving within the region. Tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity.

Why or why not ? The biology of skin color
Answer:
No
Explanation:
No skin color is perfect in ANY environment. One of the uses of melanin (A primary skin pigment) is to absorb ultraviolet rays from the sun that initiate Vit. D production.
So an abundance of melanin is beneficial in an an environment with a large amount of sun to prevent an excess of Vit. D in the blood.
Inversely, less melanin is useful to an individual in an environment that gets little sun since there is not as much melanin to inhibit Vit. D production, and thus is less likely to have a Vit. D deficiency.

How do salt ions/water move through a semi-permeable membrane? What is required for their transport?
Answer:
Water passes through the membrane in a diffusion process called osmosis. During active transport, energy is expended to assist material movement across the membrane in a direction against their concentration gradient. Active transport may take place with the help of protein pumps or through the use of vesicles.
