Biology Questions

We know that the circulatory system of our body is a loop. The Heart is the pump, the arteries and their smaller branches (arterioles) carry oxygen rich blood all through your body tissues from the heart and the veins and their smaller branches (venules) carry oxygen depleted blood and waste products back to the heart from all the body parts.

A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine. 

A nucleotide within a chain makes up the genetic material of all known living things.

There are 3 stages in cellular respiration. They are:

1. Glycolysis

2. Kreb's cycle

3. Electron transport chain

Here, Glycolysis produces only 2 ATP whereas Kreb's cycle produces no ATP. Electron transport chain of the cellular respiration produces the maximum ATP.

The digestion process starts in the mouth and the complete digestion process completes in the small intestine where all the nutrients in the food are absorbed.

Antipsychotic drugs have proved helpful in the treatment of schizophrenia and other psychotic disorders, inhibits dopamine, reduces delusions, hallucinations, thought disorganization.

The nucleus of a cell contains chromosomes, which carry genetic information in a long molecule called DNA.

Genes are regions of DNA that carry the code to control a particular cell activity or the production of a particular protein.
