Chemicals released for causing allergy

Assume that the total surface area of a human body is 1.6m^(2) and that it radiates like an ideal radiator. Calculate the amount of energy radiates per second by the body if the body temperature is 37^(@)C . Stefan constant sigma is 6.0xx10^(-8)Wm^(-2)K^(-4) .

When body is weighted on an ordinary balance we demand that the arm should be horizontal if the weights on the two pans are equal. Suppose equal weights are put on the two pahns, the arm is kept at an angle with the horizontal and released. Is the torque of the two weights about the middle point (point of support) zero? Is the total torque zero? If so, why does the arm rotate and finally become horizontal?

Name the antibody responsible for allergic reaction.Also mention two chemicals released during allergic response.

Endocrine glands control and co-ordinate the body functions through secreting certain chemical messengers called hormones. Due to certain physiological reasons, the blood glucose level of otherwise normal persons increases. What is the chemical nature of this hormone? Discuss its role in the body.

Alcohol is removed from the body by the lungs, the kidneys, and by chemical processes in liver, At moderate concentration levels, the majority work of removing the alcohol is done by the liver, less than 5% of the alcohol is eliminated by the lungs and kidneys. The rate r at which the liver process alcohol from the bloodstream is related to the blood alcohol concentration x by a rational function of the form r(x)=(ax)/(x + beta) for some positive constants a and b. Find the maximum possible rate of removal.

Assertion : The bases of nitrogen containing molecules having the chemical properties of a base are the nitrogenous bases of DNA. Reason: Because they release H^(+) ions or protons in solution.
