Alexxx [7]

Answer: (c) can undergo self-renewing divisions for the lifetime of a healthy animal.

Explanation:

The adult hematopoietic tissue or adult hematopoietic stem cells can be found in bone marrow of the animal. These cells have the ability to regenerate and renew so that the production of red blood cells remains continuous till death. Hematopoiesis can be defined as the production of cellular components of blood. The adult hematopoietic stem cells are located in the flat bones and ends of the long bones.

The total amount of ATP that a cell gains for each glucose molecule that enters glycolysis depends on the presence of carbon dio

liraira [26]

<h2>Glycolysis Process</h2>

Explanation:

<u>True is right Answer</u>

The procedure of glycolysis creates a net increase of two pyruvate atoms, <em>two ATP particles, and two NADH atoms for the cell to use for vitality. </em>
Cell breath produces 36 absolute ATP for every atom of <em>glucose across three stages.The first stage, glycolysis, happens in the cytosol and nets 2 ATP while parting the six carbon glucose into two three-carbon pieces. Breaking the bonds between carbons in the glucose atom discharges vitality. </em>
ATP yield during oxygen consuming breath isn't 36–38, however just around 30–32 ATP particles/1 atom of glucose .
The TCA cycle and beta oxidation are utilized by the mitochondrial electron transport chain to create ATP.It formed FADH2 and NADH.
Complete oxidation of one palmitate particle (unsaturated fat containing 16 carbons) produces 129 ATP atoms.
The procedure can be abridged as glucose + oxygen → carbon dioxide + water. During this procedure, the vitality put away in glucose is moved to ATP. Vitality is put away in the bonds between the phosphate gatherings (PO4-) of the ATP particle.

On the graph below, what would explain why the rabbit population levels drastically increased instead of decreasing drastically?

Ilia_Sergeevich [38]

Based on factors affecting population, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

<h3>What is population increase?</h3>

Population increase refers to the increase in the number if species of an organism found in a given habitat over time.

Increase in population can be brought about by factors such as;

abundance of food
high fertility rate
favorable environmental conditions
lack of predators

Therefore, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

What’s the difference between eukaryotic cell walls and prokaryotic cell walls?

Anton [14]

Eukaryotes have a nucleus with a membrane, larger ribosomal subunits, usually reproduce sexually, and may not have a cell wall. Prokaryotes have no membrane around the nucleus, smaller ribosomal subunits, reproduce asexually, and do have cell walls.
