Correct Answer: Fascicles
Correct Answer: limited
Explanation:
As an infant, the ability to produce antibodies is limited.
Correct Answer: Both A & B
Explanation:
The processes both osmosis and diffusion come under passive transport and require no energy. The movement of solute from the region of higher concentration to the region of lower concentration is nothing but diffusion.
Correct Answer: histones
Correct Answer: entering the nucleus of a cell and initiating or altering the expression of a gene
Explanation:
Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.
Correct Answer: Water
Explanation:
A nutrient is a substance used by an organism to survive, grow, and reproduce. These are compounds in foods essential to life and health, providing us with energy.
There are two types of nutrients:
1. Organic Nutrients
2. Inorganic Nutrients
Carbohydrates (CHO), Lipids (fats), Proteins and Vitamins come under organic nutrients as they contain carbon. These can add fat to the body.
Minerals and Water come under inorganic nutrients as they lack in carbon. These cannot add fat to the body.
