Answer:
0.4550
Explanation:
In this example, R allele is dominant, so individuals RR and Rr can roll their tongues. If in a population of 1000 gorillas, there are 575 gorillas who can roll their tongues, they will be RR and Rr.
In this case, there is Hardy Weinberg Equilibrium, so the following will be true:
Where:
frequency of RR
frequency of Rr
frequency of rr
The question is what is the frequency of heterozygotes, or, what is the value of 2pq.
We know that RR+Rr is 575 individuals in a population of 1000, or 0.575.
In other words:
So, it is possible to find 
:
Now, there are two alleles in the population, so the following will be true:
It is possible to find q (the frequency of allele r) and p (the frequency of allele p):
Therefore:
Now, the frequency of heterozygotes or 2pq is:
Answer:
Laws=C
Conservation=D
Politics=A
Regulation=B
Explanation:
Laws are set of rules used in every community that have to be followed so the community can live peacefully together. This definition matches C.
Conservation means to cleverly store or save something. This definition matches D.
Politics are things involved in the government.
This meaning matches A.
Regulations are similar to laws but they have a difference. The answer is B.

Answer:
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Beyond durability, cockroaches are built to play defense. They have an exoskeleton to protect their soft bodies, and will hide whenever they're in the process of molting their exoskeleton. The exoskeleton is not only rigid but flexible to allow the roach to crawl into tiny crevices. Their legs are built for running
A way for animals to avoid competition.
