Answer:
The correct answer is - 2 variable or factors,
1. normal or vegetarian diet, and
2. restricted or unrestricted diet.
Explanation:
The presented experiment is designed to see if the diet has a role in reducing high blood pressure. In this experiment two factors, a low salt diet and a vegetarian diet believed to have a promising effect.
Men with high blood pressure are assigned to random diets but these randoms diet has two common factors which are normal or vegetarian diet and restricted or unrestricted salt diet to check their individual effect on reducing high blood pressure.
Thus, the correct answer is - 2 variable or factors,
1. normal or vegetarian diet, and
2. restricted or unrestricted diet.
There are four main types of chromosomes: metacentric, submetacentric, acrocentric, and telocentric. Chromosomes are found within the nucleus of most living cells and consist of DNA that is tightly wound into thread-like structures.
Sunlight ( the source of energy), air (composed mainly of oxygen and carbon dioxide), water, food (nutrients), temperature (a habitat with a right temperature for different kind of organisms).
Fatty acids are the building blocks of lipids
WHAT ARE LIPIDS?
- Lipids are one of the four major biological molecules in nature (the other three are proteins, carbohydrates and nucleic acids).
- Lipids are organic compounds that are generally characterized by their insolubility in water.
MONOMERS OF LIPIDS:
- Lipids, like every other biological molecule, are polymeric compounds i.e. they are made up of smaller monomeric units. The monomers that make up lipids are called FATTY ACIDS.
Therefore, fatty acids are the building blocks of lipids.
