Answer:
The correct answer will be option-B.
Explanation:
The student performed the experiment to study the effect of talking to plants on the growth of plants. He wanted to study "talking as an experimental variable".
While experiment he divided the samples into control group as well as the experimental group but he mixed the other variables like watering the plants using various methods-directly or with sprinkles in different amount.
This mixing of variables will cause interference with the conclusion as one will not be able to suggest that the growth pattern in plants is the result of the talking or watering. Also, the amount of water as well as mode of providing water differed in the experimental group.
Thus, Option-B is the correct answer.
Answer:
first- class proteins comes from eggs , meat , fish and dairy products while non - animals related foods ,like vegetables and fruits, provide second - class proteins . first - class proteins contain a necessary amount of these important amino acids , but second - class proteins only contains some of them.
Explanation:
Answer: Deforestation is bad for mother nature. The reason for this is because deforestation is cutting down trees and in that way we are destroying mother nature's gifts to us.
b. Lipids
c. Carbohydrates
d. Protein
The Nutrients that contains the most calories per gram are lipids (or fats), with 9 calories per gram compared to 4 calories per gram in both protein and carbohydrates.
Your question asks which one of the following nutrients that contains the most calories per gram.
The answer is lipids (or fats).
When we look at calories per gram, which is a measure of energy density, lipids contain more calories per gram than protein and carbohydrates.
In fact, lipids contain 9 calories per gram, while protein and carbohydrates each contain 4 calories per gram.
Vitamins do not contribute calories, but they are essential for various bodily functions.
This is why fatty foods are considered calorie-dense, meaning they have more calories per unit mass than other nutrients.
For example, animals tend to seek lipid-rich food for their higher energy content due to the high caloric content.

The correct option is (b) Lipids.
Further Explanation:
Certain molecules or polymers are present in all the living organisms those molecules are known as biomolecules that include protein, carbohydrate, and fats. These different molecules provide a differential amount of energy to the living system.
Proteins- are the polymers that are made up of amino acids. Amino acids are linked to each other through peptide molecules.
Carbohydrate- they are the polymers that are made up of monosaccharide to further form disaccharide and polysaccharide. The bonds present between the sugar units in the carbohydrate molecules are known as the glycosidic bond.
Lipids- they contain long chains of fatty acids. It provides high energy or calorie per gram.
Vitamin- they are just the organic molecules that are required in low quantity by the organism to sustain life. It includes vitamin b, a, d, c, k, etc.
