A primary oocyte residing in a primordial follicle becomes a secondary oocyte "in the vesicular follicle".
Answer:
food, water, and breathing space
Explanation:
Empathy is a feeling that, in short, represents the ability to put yourself in the other person's shoes. This encompasses thoughts, actions or feelings regarding whatever subject is being addressed.
<h3>Can evolution explain the types of primates in the group into which they will organize themselves?</h3>
As they age, the saddles become larger and eventually cover most of their backs. The most common social group pattern among semi-terrestrial primates is the multimale-multifemale group. With this pattern, there are no stable heterosexual bonds--both males and females have a number of different mates.
<h3>How is Homo sapiens different from other non-human primates?</h3>
Upright posture, arms shorter than legs, extraordinary brains. While the natural "lottery" acted on these and other characteristics, primitive man climbed a new rung of the evolutionary scale. "In evolutionary terms, it is important to think that it is not adaptation that arises to respond to environmental needs; a variation happens and the environment ends up favoring it"
With this information, we can conclude that We are all descendants of Homo sapiens that originated in Africa. Thanks to genetics, we know that all Homo sapiens are descended from an African woman who lived about 200,000 years ago.

If a hypothetical poison prevent nucleoli from carrying out their functions, the cell organele that will be affected is the RIBOSOMES.
Nucleoli of the cell is the one that is responsible for production of ribosomal sub units; it uses proteins and ribosomal RNA to do this. It then send the sub units to the interior of the cell where they are assembled.
Ribosomes make proteins in the cells. Thus, if nucleoli is affected, ribosome will not be produced and ultimately proteins will not be produced in the cells.
Answer:
True
Explanation:
Point mutations arise when a single amino acid base is changed. This could cause some differences in the organism or it may not. Manufactured point mutations in model systems such as yeast offer a powerful tool to examine the function of different amino acids in a protein.
There are three types of point mutations
- Silent: these mutations have a single residue change but it does not affect the amino acid that is being coded. There is no change to the wild type
- Nonsense: will cause a stop or start or gain of start/stop codon.
- Mis-sense: will cause a change of amino acid residue. There are two types of mis-sense Conservative and non-conservative. The former will cause a change in amino acid base to one that has similar properties while the former will change to an amino acid of different properties often having different traits than the wild type.
