Phosphate groups of the nucleotides in the diagram are marked with W.
Option C.
<h3><u>Explanation:</u></h3>
DNA is a macro molecule which is formed of polymerization of deoxyribonucleotides. Four types of deoxyribonucleotides are present which are adenosine, guanosine, thymidine and cytosine triphosphate. These nucleotides are polymerized based on the genetic setup.
The phosphate groups attached with the sugar molecule are actually polymerized with the o glycosidic bond. That's marked with the letter W. These phosphate molecules are attached with the sugar molecules which actually are attached with the nitrogen bases. They in total forms a nucleotide, hence the whole DNA. X in the diagram are nitrogen bases and the Y are the hydrogen bonds between the complementary nitrogen bases
C. Serving as a Shock absorber and cleaning agent
Answer:
Glucose can used as a substrate and broken down in plant cells by the process of respiration. The chemical energy released by respiration can be used by the plant for cellular activities such as protein synthesis or cell division
Explanation:
<h2>Answer:</h2>
The option A, B and E are correct.
<h3>Explanation:</h3>
Homeostasis is the ability or tendency to maintain internal stability in an organism to compensate for environmental changes. An example of homeostasis is the human body keeping an average temperature of 37 C degrees.
Homeostasis, any self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival.
So for the existence of living organism homeostasis is important.
Statements A, B and E apply to the definition of homeostasis.
