I've had doctors say it's ok to drink coffee while sick, some say other wise. 99% of the time people recommend tea. I'm just curious to what reddit thinks. If you're a coffee addict, you should definitely drink your normal amount. Definitely, an irritable sick person with a headache is no fun. There is powder caffeine for this purpose if you really need your fix but for a true coffee addict, nothing but the elixir itself will do.
Why do you think species remain in a stage of stasis? A. A stable ecological niche leads to absence of selection pressure, which in turn causes species to remain unmodified or in stasis.B.

Sperm and egg undergo fusion to a zygote. The zygote will undergo developmental stages and growth to eventually form an individual of a specie. The number of chromosomes must be constant in a specie. To maintain a constant number of chromosomes in species the gamete cells undergo meiosis. Meiosis is the reduction division because it reduces the number of chromosome. It only occurs in diploid cells and reduces the diploid cells (2n) to haploid cells (n) eg: gamete cells. Both gametes after meiosis will have half the number of chromosomes and when fusion occurs the original chromosome number is restored ensuring constant number of chromosomes in species. To simply say it if gametes are not haploid the same chromosome number in species will not be retained.
