Answer:

The correct answer is - The growth and tissue repair are the major purpose of mitotic cells in multicellular organisms.

Explanation:

The purpose of mitotic cell division in multicellular organisms can be understood by the three points:

1. somatic cells divide through mitotic cell division.

2. Every multicellular organism shows growth and develop with time in size

3. Every cell of the body is repaired with the help of the mitosis that replaces the damaged cell with the new cell.

Single-celled eukaryotes show asexual reproduction by binary fission which is a form of mitosis.

Answer:

b. reducing molecules

Explanation:

Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.

In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.

Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.

On Florida's beaches, what plant plays a vital role in the development of sand dunes? sea grapes beach sunflower sea oats saw pa
andrew11 [14]
Answer - sea oats

Sea oats play a vital role in the development of sand dunes. The structure of their leaves and roots help in the trapping of the wind blown sand, promoting the growth of sand dunes and their stabilization. Sea oat plantation is encouraged in coastal areas to protect damage from heavy winds and high tide.
