Correct Answer: Ribosomes
Correct Answer: Lysosomes
Explanation:
Lysosome is an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane. They are capable of breaking down all types of biological polymers like proteins, nucleic acids, carbohydrates, and lipids.
Lysosomes are known as the suicide bags of cells because whe any cell gets damaged these organelles burst and the enzymes present in it will digest the damaged cell.
Correct Answer: H2CO3
Correct Answer: Interstitial cells
Explanation:
Androgens such as testosterone are produced by the Interstitial cells.
Correct Answer: Excess carbohydrates and fats are stored; excess proteins are not.
Explanation:
All proteins, carbohydrates and fats are macronutrients that we need to make living. They contribute to 90% of the dry weight of our diet.
From the given options, Excess carbohydrates and fats are stored; excess proteins are not.
