FAQ on Life Processes Class 10 MCQ Online Test

Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?

Answer: In multicellular organisms like humans, all the body cells are not in direct contact with the surrounding environment. Therefore, every cell of the body will not get oxygen as per need by the process of diffusion from the environment. Therefore diffusion is insufficient to meet the oxygen requirements of multicellular organisms.

What criteria do we use to decide whether something is alive?

Answer: The main criteria used to decide whether something is alive are breathing and respiration. However, living beings also show growth and movement.

What are outside raw materials used by an organism?

Answer: Any organism uses organic molecules as raw material. Heterotrophs use food and autotrophs use carbon dioxide, minerals, water, and all organisms use oxygen (for respiration) as raw materials.

What is the function of digestive enzymes?

Answer: The food we eat is complex in nature, i.e., it contains complex molecules. Digestive enzymes break down these complex molecules into smaller simpler molecules so that they can be absorbed by the walls of the intestine.

  1. EXPLAIN THIS QUESTION Single circulation, i.e., blood flows through the heart only once during one cycle of passage through the body, is exhibited by which of the following:

    Reply
    • Blood flows through the heart only once during one cycle of passage through the body, this is called single circulation which is exhibited by Hippocampus, Exocoetus and Anabas. Here the blood flows only once through the heart during one cycle of passage through the body. It occurs in fishes. This is less efficient as gill capillaries slow down the blood flow, hence the body receives blood at a low pressure which decreases the rate of oxygen supply to the cells.
