13. Plants absorb water from the soil to prepare their own food. Which of the following factors will decrease the absorption of water by the plants?
    (a) Decrease in soil temperature
    (b) Decrease in the rate of transpiration
    (c) Increase in the number of root hairs
    (d) Decrease in the amount of water in the soil
    Correct Option: (d) Decrease in the rate of transpiration
    Solution: Transpiration results in the loss of water from the aerial parts of the plant. This creates a suction pull in the vascular tissues which is ultimately responsible for the absorption of water from the soil. Decreased rate of transpiration will decrease the absorption of water by the plants.
    
    
14. The generation of suction pull in plants plays an important role in moving minerals and water from the roots to other parts of the plants. The generation of suction pull takes place due to the evaporation of water from the leaves. Which of the following factors will favour the rapid transport of materials in plants?
    (a) Absence of air currents
    (b) Increased relative humidity
    (c) Less absorption of water from the soil
    (d) Increase in environmental temperature
    Correct Option: (d) Increase in environmental temperature
    Solution: Increase in temperature increases the rate of transpiration. As a result, more water will be lost from the leaves. This will generate a greater suction pull and ultimately favour the rapid transport of materials in plants.
    
    
15. Which of the following does NOT relate to the regular need for blood donation?
    (a) Blood has a limited shelf life.
    (b) Every 2 seconds someone needs blood.
    (c) It improves the blood circulation of the donor.
    (d) Blood cannot be manufactured outside the body.
    Correct Option: (c) It improves the blood circulation of the donor
    Solution: There is a constant need for a regular supply of blood because it can be stored only for a limited period of time before use. Regular blood donation by a sufficient number of healthy people is needed to ensure that blood will always be available whenever and wherever it is needed.

20. What will happen if both the kidneys of a person are damaged? What will you suggest helping the person to survive?
    Solution: In humans, kidneys are the chief organs of excretion. They help in the elimination of nitrogenous waste products and maintaining fluid balance. If one of the kidneys is damaged, the other kidney is capable of performing the functions properly. However, if both the kidneys are damaged, it leads to death. This is because of the excessive accumulation of nitrogenous waste products in the blood. Such patients cannot survive unless their blood is filtered periodically. This is done with the help of an artificial kidney-like equipment. This device performs the functions of a kidney but is present outside the body. This process is called dialysis.
    
    
21. How does water move up in tall trees?
    Solution: Roots absorb water and minerals from the soil continuously. Most of the water is utilised by the plant while the remaining water evaporates through the stomata present on the surface of the leaves by the process of transpiration. Evaporation of water from the leaves creates a suction pull which causes the water to move upwards. In this way, water can be pulled to great heights in tall trees.

    Assertion-Reasoning Questions
    
    Below questions consist of two statements – Assertion (A) and Reason (R). Answer these questions selecting the appropriate option given below:
    
    
    
24. Assertion (A): The average heartbeat of an adult person at rest is 72 to 80 beats per minute.
    Reason (R): Each heartbeat generates one pulse in the arteries and the pulse rate per minute indicates the rate of heartbeat.
    Correct Option: (a) Both A and R are true but R is not the correct explanation of A
    Solution: The average heartbeat of an adult person at rest is 72 to 80 beats per minute. The number of heartbeats increases during physical exercise or when a person is excited. Each heart beat generates one pulse in the arteries and the pulse rate per minute indicates the rate of heart beat.
    
    
25. Assertion (A): Animals such as sponges, and Hydra do not possess any circulatory system.
    Reason (R): Entry of food and oxygen and removal of wastes occurs through the water in which they live.
    Correct Option: (b) Both A and R are true and R is the correct explanation of A
    Solution: Animals such as sponges, and Hydra do not possess any circulatory system. The water in which they live brings food and oxygen as it enters their bodies. The water carries away waste materials and carbon dioxide as it moves out. Thus, these animals do not need a circulatory fluid like the blood.
