Answer:

Limits platelets population.

Explanation:

The result of this  modified cell cycle would be the presence of limited population of this cell because no mitosis occurs in these cells. Mitosis is a type of cell division that increases population of the cells. These megakaryocytes are changed into platelets by releasing protoplatelets that break up into a number of smaller and functional platelets. These platelets skip mitosis and cytokinesis process which limits their population in the body.

Give an example of how a biome is an open system from the point of view of the biosphere, atmosphere, lithosphere, and hydrosphe
Karolina [17]

Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.

<h3>What is the biome?</h3>
  • The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
  • In order to describe an open system, we say that the system must have external interactions.
  • A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
  • The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
  • A prime example is the movement of water through each of the spheres.

Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

Pyruvate carboxylase and phosphoenolpyruvate carboxykinase catalyze reactions of gluconeogenesis that bypass the reaction of gly
dem82 [27]

Pyruvate carboxylase and phosphoenolpyruvate carboxykinase catalyze reactions of gluconeogenesis that bypass the reaction of glycolysis that is catalyzed by pyruvate kinase.

<h3>Gluconeogenesis:</h3>

The tissues of some organs, including the brain, the eye, and the kidney, use glucose as their primary or only source of metabolic fuel. Glycogen stores become exhausted during a protracted fast or intense exercise, and glucose must be created from scratch to keep blood glucose levels stable. The process through which glucose is created from non-hexose precursors such glycerol, lactate, pyruvate, and glucogenic amino acids is known as gluconeogenesis.

Glycolysis is effectively reversed during glucose synthesis. However, gluconeogenesis makes use of four distinct enzymes to skip the three highly exergonic (and essentially irreversible) phases of glycolysis. The pyruvate carboxylase, PEP carboxykinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatase enzymes are specific to gluconeogenesis. Gluconeogenesis can only take place in particular tissues because these enzymes are not found in all cell types. In humans, the liver and, to a lesser extent, the renal cortex are the primary locations for gluconeogenesis.

What happens once a person is infected with a heprevirus?
hram777 [196]
<span>Herpesviridae is a large family of DNA viruses that cause diseases in animals, including humans.

When a person infected once, his immune system develops antidot against the virus, so he becomes immune for that virus for rest of his life. In other words, he can't be affected from that virus again

Hope this helps!</span>
