arsen [322]

Answer:

The correct answer is C.

Explanation:

The amount of genetic variation in two humans is 0.1 percent of their genome. Human genetic variation refers to the biological difference that exists in the human population.

The genetic variation in humans and apes genome is about 4 percent which is 35 million differences in a single nucleotide.

The genetic variation between apes and humans (Homo sapiens), according to scientists includes gene expression differences, variation in the transportable elements and type and number of repetitive genomic DNA transportable elements, the difference in the gene sequence, single nucleotide polymorphic, etc.

According to research, 97 percent of humans and orangutans genomes are identical. Based on evolution, among all apes, the orangutans are very special as it has been stable for the past 15 million years.

Therefore, is the genetic variation between humans and orangutans is the greatest.

THe hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of __________ hemolysis on a blood agar
patriot [66]

The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.


The hydrolysis of triglycerides on a spirit blue agar plate is used for identifying bacteria based on what organic compounds they can break down, in this case lipids. Spirit blue agar is a medium that contains a supply of lipids. If bacteria have lipase, the enzyme capable of breaking down lipids spirit blue agar will be digested and it will appear as a halos around colonies of bacteria that make lipase.


The ability of bacterial colonies to induce hemolysis (the breakage of red blood cells) when grown on blood agar is used to identify microorganisms. Beta hemolysis is a complete lysis of red blood cells and in the blood agar, that area under the colonies that do the hemolysis appears lightened and transparent.
