Sweating by humans is a method of excretion. Metabolic wastes are taken out of the body through the process of sweating. Sweating also helps to cool down the body temperature because when we sweat, the water evaporates. This cools the body. Hope that helped.

Answer:
B. The 55 N cat has less mass than the 110 N dog.
Explanation:
Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object. 
In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.
Note that: if the gravitational effect is removed, the cat will contain lesser mass.
