Answer:

breaking down of glucose

Explanation:

Glycolysis, formation of acetyl CoA, Krebs cycle and the electron transport chain are all involved in the breaking down of glucose, also known as respiration, in living organisms.

During glycolysis, glucose is transformed into 2 molecules of pyruvate with ATP and NADH being generated in the process.

The pyruvate molecules are each oxidized to acetyl CoA, a process that leads to the release of carbon dioxide and the formation of NADH.

The acetyl CoAs then undergo a series of reactions, combining with a 4-carbon molecule and generating ATP, FADH2, NADH, and releasing carbon dioxide. The 4-C molecule is also regenerated during the process. This is known as the Krebs cycle.

All the FADH2 and NADH made from the earlier steps then enter the electron transport chain where they donate their electrons to become FAD and NAD respectively. ATP is generated and water is formed through the reduction of oxygen.

OLga [1]

Answer:

a) produced the oxygen in the atmosphere

Explanation:

Prokaryotes are likely to first form of life on earth and they existed billions of years ago before animals and plants.
As these prokaryotes can do photosynthesis so there most important function is produce oxygen in atmosphere for the evolution of aerobic life.
At that time the conditions were harsh on earth so these prokaryotes are used to survive under earth like in oceans. They first produce oxygen in oceans.
In eukaryotes photosynthesis emerge by endosymbiosis with photosynthetic prokaryotes.

The right atrioventricular valve (tricuspid) regulates the opening between the _________ and the _________.

Ksju [112]

Answer:

The right atrioventricular valve (tricuspid) regulates the opening between the right atrium and the right ventricle.

Explanation:

Valves are gates that allow the connection between atria and ventricles. The two valves located on the right side (tricuspid and pulmonary) direct the incoming blood from the body to the lung, where it is oxygenated; from there it returns to the left atrium, to later pass through the mitral and aortic valves. The left atrium connects to the left ventricle through the mitral valve and the right atrium connects to the right ventricle through the tricuspid valve.

100 points and Brainliest!!! Plus, an opportunity for an extra 100 points if correct.

rewona [7]

Answer:

Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.
