7. Challenge yourself: You have already learned that mutation is one source of
variation in a population. Based on what you have just seen, what is a second
source of variation?
(I just need more information or explanation) please

Answer:

30%

Explanation:

Considering that the amount of Cytosine added to the amount of Guanine is 40%, that explains that Cytosine and Guanine each equal to 20%.

Now, the remaining bit is 60%. Since Adenine and Thymine both equal the same, that would mean: 60/2 = 30.

Cytosine and Guanine pair together and will always be equal to one another. The same goes for Adenine and Thymine. (A=T, C=G)

Always remember that you want it to total up to 100% at the end.

A type of mountain formed when magma collects beneath an overlying rock layer, forcing the layer upward into a blister-like structure is known as a domed mountain.

Magma has been defined as the molten or the semi-molten material which is natural and from magma all igneous rocks are formed. Beneath the surface of the earth magma has been  found and there are very proofs of magmatism and it has been observed on the other terrestrial planets as well as some of the natural satellites.

Sedimentary rocks are generally made up from directly heat and these are formed when deposition or accumulation of particles that are organic or minerals at the surface of Earth, later followed by the process of cementation. The main feature of sedimentary rock is that they are formed in multiple layers.The rocks are made up of more than one mineral and the size of some rocks are small or big it depends upon their constituents.

Therefore, A type of mountain formed when magma collects beneath an overlying rock layer, forcing the layer upward into a blister-like structure is known as a domed mountain.
