Answer:
B. Directional selection
Explanation:
When natural selection starts to choose one phenotypes that is an extreme (as in, a really small neck or a really long neck), this is an example of <u>directional selection.</u> It makes sense for giraffes to have evolved this way, because the longer the neck, the more ably they can eat food from high branches. The more food they could get, the more chance of reproduction, the more "evolutionarily fit" they are.
Stabilizing selection is when national selection picks average phenotypes (like a medium-sized neck). Disruptive selection is when the extremes are both picked (like all the medium-sized neck giraffes die, and two different species start to emerge). Sexual selection is picking a mate based on traits. Clearly, those answers don't work here.
RNA has great capability as a genetic molecule; it once had to carry on hereditary processes on its own. It now seems certain that RNA was the first molecule of heredity, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the scene.
<h2>Answer:</h2>
The correct answer is option C. And the full statement is:
The end product of transcription is <u>__mRNA___</u> and the end product of translation is _<u>_Proteins_</u>__.
<h3>Explanation:</h3>
- Translation and the transcription are the two main process of central dogma of life.
- DNA is the nucleotide sequence for the protein production. In this process DNA is first converted to RNA and then RNA moves to the cytoplasm for the production of proteins in the ribosomes.
- So the transcription is process in which DNA is converted into mRNA in the cytoplasm.
- In cytoplasm production of proteins by the mRNA is known as translation.
