The three components make up nucleotide are nitrogenousbase, sugar, phosphate group.
Nitrogenous Base: A nucleotide'sidentity is determined by the nitrogenous base, which is a crucial component. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four different nitrogenous bases that can be found in DNA.
A nucleotide contains a five-carbon sugar molecule as its sugar. The sugar is referred to as deoxyribose in DNA and ribose in RNA. The sugar molecule joins the nitrogenous base to the phosphate group and gives the nucleotide structural stability.
PhosphateGroup: The phosphate group is a nucleotide's third constituent. It is made up of four oxygen atoms joined by a phosphorus atom.
Thus, these are the three components make up nucleotide.

The mechanical digestion in the stomach involves the contractions of muscle smoothly. Thus, the correct answer is C.
The process of converting food into nutrients to use it as energy and for development is called as digestion. The digestion takes place mechanically and chemically.
In the chemical process of digestion, food is broken down with the help of enzymes whereas in the mechanical process of digestion food is broken down with the help of chewing from teeth or tearing.
Therefore, option C is correct as this breakdown through teeth involves contractions and relaxation of muscles.

Mechanical digestion in the stomach involves the physical breakdown of food through smooth muscle contractions, which churns and mixes the food, preparing it for further chemical digestion.
Mechanical digestion in the stomach involves the breaking down of food into smaller bits using physical force. This process includes the smooth muscle contractions of the stomach to churn the food. This mechanical churning of food in the stomach serves to further break it apart and expose more of its surface area to digestive juices, creating an acidic soup called chyme.
These contractions isolate small sections of the stomach, moving the contents back and forth while continuously subdividing, breaking up, and mixing the contents. By moving food back and forth in the stomach, mechanical digestion mixes food with digestive juices and facilitates the further process of chemical digestion.

A. alcohol termination of the grape juice by anaerobic bacteria
B. lactic acid fermentation of the grape juice by anaerobic bacteria
C. alcoholic fermentation of the grape juice by aerobic bacteria
Answer:
lactic acid fermentation of the grape juice by anaerobic bacteria
Explanation:
D. a source of energy
Monosaccharides are used by plants and animals as a source of energy.
b. activity level
c. health status
d. genetic makeup
Answer:
Activity level.
Explanation:
Metabolism is the important for the cell survival and its growth. Most of the metabolic factors does not depend upon the control of the organism and occurs itself in the body.
Some factors can be improved or controlled by the activity level. The activity level can be controlled by the individual and may affect the flexibility and may also affect the other metabolic factor. One can control its own activity level.
Thus, the correct answer is option (b).
