What is true about relative humidity?

a. It indicates how near the air is to saturation.

b. It indicates the actual quantity of water vapor in the air.

c. It is the temperature to which a parcel of air would need to be cooled to reach saturation.

d. It is the general term used to describe the amount of water vapor in the air.

D. It is the general term used to describe the amount of water vapor in the air

Explanation:

It's been a while since I've taken meteorology (2 years), but I think this is the correct answer because humidity in general refers to the amount of water vapor in the air and as we are discussing relative humidity, it cannot indicate the actual quantity of water vapor in the air (thus ruling out B). Therefore, D makes the most sense. I believe C refers to adiabatic cooling.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
