Biomolecules are important for living organisms and vital for cell structure and functioning. The cells are made up of biomolecules as their structural organization.
The four most abundant biomolecules are:
<u>Carbon, Oxygen, Nitrogen and Hydrogen</u>
The biomolecules can be explained as:
- The central biomolecules for life activities are these elements that contribute to major processes.
- The main building blocks like carbohydrate is composed of carbon, oxygen and hydrogen. They provide energy to the body by breaking into small molecules.
- Proteins are vital for cell signalling and transport. They are composed of amino groups consisting of nitrogen.
Therefore, carbon, nitrogen, hydrogen and oxygen are the most abundant biomolecules.

Answer:
Cancerous tissue has high number of mitotic index.
Explanation:
Mitotic index may be defined as the cells that undergoes mitosis by the total number of cells. Mitotic index is different in case of cancerous and normal cells.
Cancerous cells has high ability to divide continuously and requires less nutrient factors. The mitotic index of a cancerous cell is more because the number of dividing cell is more in case of cancerous cell than the normal cells.
