Which statements accurately describe humidity? check all that apply.

a. humidity is a measure of dew in the air.

b. warmer air promotes more evaporation.

c. cold air holds more moisture than warm air.

d. humidity refers to the amount of water vapor in the air.

e. areas with a lot of surface water have higher humidity than drier areas.

The correct answers are:

B. Warmer air promotes more evaporation.

D. Humidity refers to the amount of water vapor in the air.

E. Areas with a lot of surface water have higher humidity than drier areas.

The humidity can simply be described as the amount of water vapor in the air. The humidity can vary, and it can be very high in certain place for the whole year, very low at other places for the whole year, or to be changing seasonally.

The areas that have a lot of surface water (the Amazon River Basin) tend to have higher humidity than the places that lack surface water (Sahara Desert). Also, the humidity depends a lot on the temperature of the air. The warmer the air is, the higher the humidity, and vice versa, the colder the air is, the lower the humidity.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
