Answer:

Carbon is found in all living organisms. The constant flow of carbon on Earth through organisms and the air is known as the carbon cycle.

Plants absorb carbon from the atmosphere in the form of carbon dioxide.

They use it for respiration and photosynthesis.

Animals consume plants, transferring carbon along the food chain. Plants and animals respire and release carbon into air. When the animals and plants die, they are eaten by decomposers.

Carbon enters back into the atmosphere in the form of carbon dioxide gas.

Explanation:

All life on Earth is made up of a carbon-based structure. An atom of carbon has 6 electrons (4 valence electrons) that easily bond to other other compounds. Covalent bonds involve exchanging electrons; these usually are formed with oxygen, nitrogen, phosphorus and most frequently hydrogen.

This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function

Vsevolod [243]

This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function in reverse, generating ATP from ADP and Pi using proton gradients across membranes is called F-type pumps.

The inner membrane of mitochondria and bacterial plasma membranes both contain F type pumps, which are necessary for the generation of ATP.
It is also known as the ATP synthase complex or Complex V. By letting these protons passively return to the matrix, they use the proton gradient created by the flow of electrons to produce ATP.
The F1 motor is the ATP turnover motor and,
In mammals, the F0 motor, which is in charge of ion translocation, has nine subunits, nine of which are likely centered on the membrane's A, B, and C subunits, along with D, E, F2, F6, G2, and 8 subunits.

Which is the reproductive method of prokaryotes?

Verizon [17]

Answer:

Prokaryotic cells reproduce by a process that is called binary fission.

Explanation:

The DNA in such cells is contained in a single circular chromosome called a plasmid within the cytoplasm. The reproductive process starts with the replication of the chromosome.

Dafna1 [17]

I would say about her body composition is that she is within recommendations for waist circumference and percent body fat. She has a normal BMI or Body Mass Index, she has a good body composition because she is a varsity player and she is exercising her body well. So the answer in this question is she is within recommendation for waist circumference and percent body fat.
