These organs include the large intestine, skin, lungs, kidneys. Most of the wastes are products of metabolism. These waste materials that are no longer useful to the body could be in liquid or gaseous form. Examples of substances removed from the body by the excretory system are urine, feces, sweat etc.

Cells are not part of the substances removed by the excretory system.

These notes were taken during a class about biological evolution, but the subject title is missing.-results from immigration
-new genes brought into a population
-variation in a population increases

What do the notes describe?
A. gene flow
B. natural selection
C. genetic drift
D. mutation

Answers

Correct answer: A). Gene flow

Gene flow is described as the transfer of genes from one population to another population. It helps to maintain the similarities between the species and prevents the speciation.

The gene flow is a unifying force that prevents the population from diverging. It tries to break down the geographical boundaries, it would otherwise isolate populations.

Hence, the correct answer would be option A.

These notes were taken during a class about biological evolution describes: A. gene flow.

What is gene flow?

Gene flow can be defined as the transmission (transfer) of gene or genetic materials from a specific population of living organism to another. Thus, it helps to enhance and maintain the similarities and unique characteristics that exist between the species of organisms which are living in an ecosystem while preventing speciation.

In conclusion, we can deduce that these notes which were taken during a class about biological evolution describes gene flow such as an increase in population variation or genetic drift.
