the mitochondrion is host to which portion of cellular respiration? glycolysis alcoholic fermentation lactic acid fermentation t
MA_775_DIABLO [31]

Answer: The correct answer is Kreb cycle.

Cellular respiration is defined as the oxidation of food into CO₂ ( cabon dioxide) and H₂O ( water) in order to produce energy in the form of ATP ( adenosine triphosphate).

It occurs in three stages that is Glycolysis, Kreb cycle, and Electron transport chain.

Kreb cycle occurs in the matrix of the mitochondria. It includes the oxidation of a two carbon compound that is Acetyl- CoA in order to generate a pool of chemical energy in the form of ATP, NADH, FADH₂.

On the contrary, glycolysis and fermentation occur in the cytoplasm.

Thus, mitochondria is host to Kreb Cycle of the cellular respiration.

When the polymerase chain reaction (PCR) is used to amplify segments of DNA, the sample is first heated, and then cooled, in cyc
baherus [9]

Answer:

At least 17 PCR cycles or 16 PCR cycles

Explanation:

As we know -

In one chain of  heating and cooling  of polymerase chain reaction (PCR), the strands of DNA gets doubled.

The general mathematical representation of this is

{2^n - (2 *  n)}

where "n" is the number of PCR cycles.

It is given that DNA strands  to be produced is 16 times the original quantity of DNA.

So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less  than 16 times the original quantity of DNA

A cell with 10 chromosomes undergoes mitosis. Indicate how many chromosomes would be expected in each of the daughter cells?
Marina86 [1]
Mitosis is the process by which a parent cell divides into two daughter cells that are genetically identical to each other and to the parent cell. The parent cell of 10 chromosomes will end up becoming two daughter cells that each have a copy of those 10 chromosomes.
Hope this helps! :)
