Answer:
40%
Explanation:
Remember that guanine always pairs with cytosine, and thymine always pairs with adenine. That means that any time there is a guanine, there is always a cytosine.
If there are 10% guanines, then there are 10% cytosines. That means the total of guanines and cytosines is 20%.
The other 2 bases (thymine and adenine) have to make up the rest of the bases. That means they have to make up 100-20 = 80%.
Again, there will be equal amounts of thymine and adenine, so 80%/2 = 40%.
In a ring species gene flow occurs between neighboring populations of a species, but at the end of the ring populations don’t interbreed.
Answer:
<u>A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads.</u>
Explanation:
Removing non-native species from the environment helps the native ants to thrive without having any changes in the ecosystem effect them (i.e. new invasive animal).
Creating laws to prohibit fishing from local streams helps keep the fish alive and allowing them to continue to use this stream.
Planting trees and other plants to attract native species helps secure and grow the ecosystem of that area.

They exist in all the cells of the body. They are inherited via sperm and egg cells.
They will not be inherited unless a similar damage has happened in eggs or sperms due to the same exposure to mutagen, In that case, progeny might show the mutation.
But they are an inherited mutation that was supported in fertilization of the egg during reproduction.
