Answer:
There are four chambers of the heart:
The two bottom chambers are the right ventricle and the left ventricle.
The two top chambers are the right atrium and the left atrium.
The question is incomplete as it does not have the options which are-
a. migration
b. genetic drift
c. mutation
d. stabilizing selection
Answer:
The correct answer will be option- migration
Explanation:
Migration refers to the long-distance movement of the individual, group and population. The migration enables the flow of genes from one population into another called gene flow. Migration is the strongest force of gene flow after selection.
In the given case, since the allele frequency of the population has changed due to the migration of the 200 snakes from a population of 5000 snakes, therefore, migration is the correct answer.
B; none of the above.
Explanation; all of the other options have specific outcomes that do not lead to genetic variation.
The kind of investigation used in the scenario above will be either primary or secondary investigation.
<h3>Why would they use primary or secondary investigation?</h3>
If they wanted to carry out an investigation from scratch using their own parameters, case-controls, and random sampling from scratch perhaps so they can have control, then that would be the primary investigation.
Secondary investigation on the other hand gleans off information already researched and provided at the primary investigation level.
