How do you tame a horse in
and why should i never use my diamonds on a farming tool? ?

taming - by feeding it something. you'll see the hearts appear, and after a while, it will be tamed. then, to ride it, you'll need a saddle.

as for the diamonds, that's a waste, bkz the work is done best by iron.

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.
