Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by: mutation. random mating between organisms.
Mitochondria contains it's own DNA. It's structure is a bit different from that of the chromosomes found in the eukaryotic nucleus. From my understanding, it supports the endosymbiotic theory because it contains characteristics similar to single-celled prokaryotic cells despite it being classified as an eukaryotic cell.
<span>Another function of the mitochondria that supports the endosymbiotic theory is that the mitochondria are responsible for their own reproduction. Eukaryotic cells are duplicated by its nucleus, however, despite it being classified as an eukaryotic cell, the mitochondria does all the work on it's own. Again, it supports the endosymbiotic theory because it contains characteristics similar to single-celled prokaryotic cells despite it being classified as an eukaryotic cell.

Answer:
b. False
Explanation:
The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.
A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.
- The rate of bacterial cell reproduction varies from a particular species to another.
- Varying species have different absorbance thresholds.
Answer:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. While Coronary circulation is the circulation of blood in the blood vessels that supply the heart muscle (myocardium).
