Which of the following is a true statement?
FrozenT [24]

Answer:

a. Anabolic pathways build molecules, require energy, and are endergonic.

Explanation:

<em>Anabolic pathway </em>describes the metabolic reactions that<em> </em><em>build up</em><em> complex molecules from simpler ones</em>, typically via condensation (monomers covalently joined producing water as a by-product).<em> It </em><em>requires energy </em><em>to construct new bonds, this means is </em><em>endergonic</em><em>.</em>

The catabolic pathway, on the other hand, describes metabolic reactions that<em> </em><em>break complex molecules down </em><em>into simple ones</em>, typically via hydrolysis (consumption of water to break bonds within the polymer). <em>It </em><em>releases energy </em><em>when these bonds are broken, this means it is </em><em>exergonic</em><em>.</em>

Considering this information we can conclude that the correct answer is a. Anabolic pathways build molecules, require energy, and are endergonic.

I hope you find this information useful and interesting! Good luck!

STALIN [3.7K]

Answer:

multicellular.

Explanation:

Organisms exhibit various levels of organization of the body. It includes cellular level, tissue level, organ level, organ system level of organization. The unicellular organisms have single cells as their bodies and therefore do not have the genes that regulate the various parts of the body rather than the individual cells. Prokaryotic are unicellular organisms only and do not have multiple cells in their bodies. Therefore, the mentioned genes are the regulatory genes that coordinate the functioning of various parts of the body of a multicellular organism. For instance, the genes involved in regulation of blood glucose levels.

Apart from suffering from recurrent and prolonged infections, Marie Curie also experienced the following signs and symptoms: fat
Nataly [62]

Answer:

See below

Explanation:

Marie Curie died of aplastic anemia in 1934. Aplastic anemia is an autoimmune disease in which the body fails to produce blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. Aplastic anaemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets.

Fatigue is a symptom of aplastic anemia as the blood doesn't have the necesarry red blood cells to transport the oxygen to the organs.

Rapid heart rate happens because the body senses the decrease of oxygen's concentration and the hearts beats faster to provide the organs of oxygen.

Pale skin happens because the blood vessels are contracted in order to provide oxygen to the important organs of the body as the brain and heart. It means that less blood reaches the face and it shows as pale skin.

Prolonged bleeding from cuts happens because there aren't enough platalets to produce a blood clot to stop the bleeding.

Dizziness happens because there is not enough oxygen arriving to the brain.

If she is A negative, she can only receive blood from others A negative donors, or O- donors. This is because she has antibodies to B, and to groups that have the protein Rh (+). So she can't receive blood either B nor Rh+.
