Answer:
Answer to 1: a black hole is a tremendous amount of matter crammed into a very small (zero) amount of space. Answer to 2: the top of your head would feel so much more gravitational pull than the tips of your toes that you would be stretched, longer and longer Answer to 3: <em><u>A black hole is a place in space where gravity pulls so much that even light can not get out.This can happen when a star is dying.</u></em> The gravity is so strong because matter has been squeezed into a tiny space. because no light can get out, people can't see black holes Answer to 4: <u>stellar, intermediate, supermassive, and miniature. </u>Answer to 5: the asymmetry of bright and dark sections of the ring are caused by the Doppler effect as the matter is coming toward Earth (brighter) or receding (dimmer).
Explanation:
The correct answer is A. Quantitative traits
Explanation:
In genetics, quantitative traits refer to traits or phenotypes (observable traits) that depend on many factors including multiple genes and actions in the environment. These traits differ from other traits because the traits tend to be more diverse in a population. In the case presented, the shell color in clams is an example of a quantitative trait because this phenotype is the result of three different each and each gene contains two alleles which means the color depends on many factors. Additionally, as most quantitative traits there is a higher variation in the phenotype considering clams can have different hues.
