Warm water near the equator rises towards the surface creating a current, what would you expect to happen to this current if the tempature at the equator decreased?

I expect it to lower its  speed. The water that goes up will be cooler(densities), the heat energy lower, and the speed smaller.

compost can be added to topsoil as a:

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.
