<u>Answer:</u> Mutations are the most fundamental way to add new genes to a gene pool.
<u>Explanation:</u>
Mutation refers to the process through which the normal sequence of altered. It may be either acquired or hereditary. It leads to addition of new genes to a gene pool.
The reason for not considering other statements as true are:
1. It is the hereditary mutation that are passed form parent to offspring's and acquired mutation is caused by external factors.
2. Acquired mutation are caused by external factors such as radiation.
3. Germ line mutation are important to evolution because they can be inherited.
B An ecosystem because it is i dont know how to explain but i think is that one
Answer:0.5 g/cm
Explanation:
calculate the density : we'll use the formula below
density = volume over mass
Usually, density will have units of
g
m
L
when dealing with a liquid or units of

when dealing with a solid.
The mass has units of grams,
g
.
The volume can have units of
m
L
or
c
m

We are given the mass and the volume, both of which have good units. All we have to do is plug the given values into the equation:
