Answer:

provides chemical energy

Explanation:

Living cells require energy to perform their various functions. This energy is obtained via the process of RESPIRATION, which is the breakdown of food molecules in order to convert the stored energy in them to a usable form by the cell. The usable form of energy by living cells is Adenosine triphosphate (ATP).

ATP is the energy currency of the cell released during cell respiration. ATP is structurally composed of Adenine (a nitrogenous base), Ribose (a pentose sugar) and three phosphate groups. ATP is a high energy carrying molecule that stores energy in the bonds that hold its phosphate group. This energy is released for use by the cell when one of the phosphate groups is released to form Adenosine diphosphate (ADP) molecule.

if you were to grill a steak, would it be better to put salt on before or after you cooked it? explain why in terms of osmosis

LUCKY_DIMON [66]

I think it'd be better to do it before you grill it cause while its on the grill it'll soak up all the seasonings and make it better tasting then it would if you would have salted it afterwards

Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.

Levene made which contribution to our understanding of DNA structure? a. He determined that the nucleus contains DNA. b. He dete

Stels [109]

Answer:

The correct answer is b. He determined that DNA contains four nitrogenous bases.

Explanation:

Levene was an American biochemist who studied the structure of DNA in the early 1900s and in 1920 he found that DNA consists of four nitrogenous bases that are Adenine, Guanine, Thymine, Cytosine.

He also found deoxyribose sugar and phosphate group and said that nucleotide is the basic unit of DNA which contains a ribose sugar with attached nitrogenous base and phosphate group.

He also concludes that an equal amount of adenine, guanine, thymine, and cytosine makes the DNA which is now known as tetranucleotide hypothesis. So the correct answer is b. He determined that DNA contains four nitrogenous bases.
