Answer:

The answer is: Folded, fault block, volcanic.

Explanation:

The main types of mountains are: Folded, fault block, volcanic and upwarped.

Folded mountains. These types of mountains tend to change constantly depending on their complexity, however they always conform to the basic type.

Volcanic mountains. It is about the mountains that come to form when a volcano erupts.

Domes. These mountains are created by domed strata, as a granitic intrusion is generated.

Mountains in block. These are large-scale structural failures. These inside are usually folded and tend to have failures.

Plateau mountains. These are created when there is activity in the deepest of the earth's crust. They are formed with the deep channels that the current water produces, where the rivers can cut any table regardless of their depth, thus producing high-rise mountains.

The answer is: Folded, fault block, volcanic.

Shark pups with the most advantageous traits are more likely to survive and reproduce. For example, pups that can hunt and feed

Ronch [10]

The answer is B. This is called genetic shift. The pups with advantageous traits are able to survive until the age of reproduction hence able to pass their genes to the next generation. Few and fewer pups with disadvantageous traits will get to reproduce hence the allelic frequencies of the shark population will shift in favour of increased hunting efficiency.

5. Concerning the nitrogen-containing bases that participate in nucleotides, what is the difference between DNA and RNA?

pochemuha

Both DNA and RNA are made up of threee basic parts: phosphate groups, sugars, and nitrogenous bases. The main difference between DNA and RNA is that the nitrogenous base thymine (in DNA) is replaced with uracil (in RNA). The other three bases remain the same, adenine, guanine and cytosine. In DNA, adenine always pairs with thymine, but in RNA, adenine pairs with uracil.
