AI Generated Solution

The correct Answer is:
To analyze the assertion and reason provided in the question, we can break it down step by step: ### Step 1: Understand the Assertion - The assertion states that "Mild fever strengthens the defense mechanism of the body." - This is true because mild fever is a natural response of the body to infection. It helps to enhance the immune response by creating an environment that is less favorable for pathogens. ### Step 2: Understand the Reason - The reason states that "High temperature is harmful and should be brought down by giving antipyretics and by applying cold packs." - This is also true. High fever can disrupt enzyme function and metabolic processes in the body, leading to a decrease in the body's ability to fight infections. ### Step 3: Analyze the Relationship Between Assertion and Reason - While both statements are true, the reason provided does not adequately explain the assertion. - The assertion focuses on the benefits of mild fever, while the reason discusses the dangers of high fever. Therefore, the reason does not support the assertion. ### Step 4: Conclusion - Since both the assertion and reason are true, but the reason does not correctly explain the assertion, we conclude that the assertion is true, and the reason is true but not a correct explanation of the assertion. ### Final Answer - The correct answer is that both the assertion and reason are true, but the reason is not the correct explanation for the assertion. ---

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five reponses (a) If both Assertion and Reason arecorrect and Reason is the correct explanation of Asserrtion. (b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion If a force is applied on a rigid body. Body is in motion but point of application of force is stationary. Then, work done by the force is zero. Reason If body is moving, then point of application of force should also move.

    A child running a temperature of 101^F is given and antipyrin (i.e. a madicine that lowers fever) which cause an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^@F in 20 min., what is the averatge rate of extra evaporation caused, by the drug ? Assume the evaporation mechanism to the only way by which heat is lost. The mass of the child is 30 kg. The specific heat of human body is approximately the same as that of water and latent heat of evaporation of water at that temperature is about 580 cal. g^(-1).

    Assertion (A) Gases do not liquefy above their critical temperature, even on applying high pressure. Reason (R) Above critical temperature, the molecular speed is high and intermolecular attractions cannot hold the molecules together because they escape because of high speed.
