Oxygen rich blood returns from the lungs to the heart. Which 2 systems are most directly involved in this process.

Respiratory and circulatory
Excretory and digestive
Circulatory and excretory
Digestive and respiratory

Answers

Answer:

Respiratory and circulatory

Explanation:

The Circulatory System Works in Tandem with the Respiratory System. The circulatory and respiratory systems work together to sustain the body with oxygen and to remove carbon dioxide. Pulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs.

The two systems which are most directly involved in this process are respiratory and circulatory systems.

What do you mean by oxygen-rich blood?

In the lungs, oxygen is put into the blood, and carbon dioxide is taken out of the blood during the process of breathing. After the blood gets oxygen in the lungs, it is called oxygen-rich blood.

During the whole process of breathing, the respiratory and circulatory systems play a major role in the separation of oxygen-rich and oxygen-poor blood.

Therefore, the two systems which are most directly involved in this process are the the respiratory and the circulatory systems.

Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?

Answers

Answer:

The correct answer is - as energy lost at every trophic level.

Explanation:

In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.

The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.

As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.

In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.

Thus the response above is right.

Two related species metabolize glucose using the exact same pathways (glycolysis, citric acid cycle, oxidative phosphorylation). Experiments show, however, that species A generates only 83% of the ATP compared to species B when provided with the same amount of glucose. What could be a potential reason for this outcome

Answers

Answer:

The correct answer is - there is a 12-Carbon ring in ATP synthase of species A whereas species B contains a 10-carbon ring.

Explanation:

ATP Synthase is a protein complex that catalyzes the transfer of the protons down the gradient build by the action of the electron system in the mitochondria and makes ATP from ADP molecules.

The higher number of carbon in ATP synthase will require more protons to rotate to produce 3 ATP in this process so, if species A has more carbon present it will take more protons and able to produce only 83% of ATP compared to species B.
