An air mass's relative humidity is a measure of how much water vapor it contains compared to how much it can contain. Different types of air masses, with different temperatures and pressures, are able to hold different amounts of water vapor. Which of the following could cause the relative humidity of an air mass to change?

A. a change in its temperature

B. a change in its pressure

C. a change in its water vapor content

D. all of these

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
