Answer: the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature.
Explanation: Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point.
Answer:
c. enzymatic breakdown of food molecules
Explanation:
For adrenergic drugs active the nervous system i.e. sympathetic also it directly related to digestive enzymes, rise the blood glucose that results in blood vessels dilation that aids delivery of nutrient and tissues.
But it does not directly affect the digestive enzymes activity after considering the secreted
Therefore in the given case, the option C is correct
Answer:

Explanation:
To differentiate: 
Solution:
Use product rule:
and the following formulae:

![(10\,sinx\,\,cos x)'=10[(sinx)'cosx+(sinx)(cosx)']\\\\=10[cosx\,cosx-sinx\,sinx]\\\\=10[cos^2x-sin^2x]](https://tex.z-dn.net/?f=%2810%5C%2Csinx%5C%2C%5C%2Ccos%20x%29%27%3D10%5B%28sinx%29%27cosx%2B%28sinx%29%28cosx%29%27%5D%5C%5C%5C%5C%3D10%5Bcosx%5C%2Ccosx-sinx%5C%2Csinx%5D%5C%5C%5C%5C%3D10%5Bcos%5E2x-sin%5E2x%5D)
