ADH controls how diluted or concentrated urine is by controlling the permeability of the collecting ducts to reabsorption of water. The antiduretic hormone(ADH) is secreted by the hypothalamus and pitutary glands. When there is less water in the blood, secretion of ADH increases and hence increasing reabsorption of water. This also applies vice versa.

Answer:
Plasmin
Explanation:
Plasmin is a serine protease also referred to as fibrin digesting enzyme, it is responsible for the dissolving or degradation of blood clot. The process by which plasmin degrades blood clot is called fibrinolysis. Note that plasmin (active) is formed from an inactive enzyme called plasminogen.
<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.
<u>Explanation:</u>
To calculate the weight of a person, we use the formula:
....(1)
where,
w = weight of an object
m = mass of the person = 65kg
g = acceleration due to the gravity of the planet
For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

where, g = acceleration due to gravity = 
G = Universal gravitational constant = 
M = mass of the planet = 
r = distance of the person from the planet = 
Putting values in above equation, we get:

Putting this value in equation 1, we get:

Hence, the weight of the person above the surface of a planet is 635.83N.
