Explanation:
Which protist group is thought to be most closely related to animals?.
Answer:
Choanoflagellates are the closest relatives of animals. They are also single-celled protists and have a flagella at one end of their cell.
Explanation:
The closest living relative of the animal is the protist choanoflagellates, that reproduce sexually and asexually.
Choanoflagellates are marine and freshwater protozoa that are widely distributed around the world. They have a distinctive flagellum with a whip-like shape and a collar made up of shorter hairs, similar to the ‘collar’ cells that filter out food in sponges.
By feeding on bacteria and debris, they feed on their larger predators and bring dissolved organic matter back into the water column. In terms of both number and feeding rate, Choanoflagellates play a vital role in the microbial food web that sustains the global ecosystem.

what is the difference between segregation and independent assortment? Will give brainiest award/ 72 points
Answer:
The Law of Segregation states that the members of each pair of alleles separate when gametes are formed. A gamete will receive one allele or the other. The Law of Independent assortment states that two or more pairs of alleles segregate independently of one another during gamete formation, so basically the Law of Independent Assortment, also known as "Inheritance Law", means that the inheritance pattern of one trait will not affect the inheritance pattern of another.

All species have a maximum tolerance limit before they are no longer suited to live in their environment. In three to five sentences, discuss the potential outcomes for a species when that maximum limit is reached. There are at least four possibilities, and one point will be assigned per potential outcome mentioned.
The potential outcome of maximum tolerance limit is reduction of population.
What is the outcome of maximum tolerance limit?The potential outcomes for our species happens when maximum tolerance limit is reached. Due to this, the population of that organism can decrease. As many species can die due to maximum tolerance limit, it can cause a reduction in reproductive rate as well as reduce life span off individuals.
So we can conclude that the potential outcome of maximum tolerance limit is reduction of population.

Your teacher describes a population of fish that live in a coral reef. Some fish are dark orange (the same color as the coral); other fish are nearly white. Human activity has led to the bleaching of the coral reefs, making them very pale in color. Over time, the population of fish will be affected. Which graph represents the type of selection that you expect to occur?
A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population and population after selection have similar curves, but the original population peaks before the population after selection.
A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The population after selection increases, decreases, increases, and then decreases again. The original population increases at the point that the original population drops.
A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population peaks at the same time as the population after selection but the population after selection peaks higher and at a more rapid speed.
A graph has trait value on the horizontal axis and proportion of individuals on the vertical axis. The original population and population after selection have similar curves but the original population is slightly higher at all points.
