Human beings do exhibit an alternation of generations, but the haploid phase is extremely deemphasized while the diploid phase is overwhelmingly dominant. The haploid phase in humans that results from meiosis is restricted to only one cell, either an egg in the female or a sperm in the male. There is never a multicellular haploid structure as there usually are in plants. If such a multicellular haploid structure is required for a true alternation of generations, then humans do not exhibit alternation of generations. The human organism grows by mitosis (the diploid phase) only after fertilization. A plant sporophyte is diploid and it produces spores by meiosis. Humans, like plant sporophytes, are diploid and make haploid gametes by meiosis.
A life cycle that humans go through.
no Unless you count it hatching, no. Think of it this way: do humans go through metamorphisis.

Everyone goes through puberty, unless your hormones are whack.
Gen 1 = The plant reproduces sexually Gen 2 = The offspring of that plant reproduce asexually and the cycle begins again, hence the name alternation ---Caveat--- This is a very simple explanation and surely there are exceptions and important details to consider depending on the exact species. For instance, triggers that can cause an alternation of generations, or sequences *how many times a the plant reproduces sexually/asexually before switching. Plant reproduction can be very complex! Good question. Just remember, all true plants will have alternating generations.
Humans go through incomplete metamorphosis. This means that there is no distinct larval stage in human development, unlike in insects that go through complete metamorphosis with distinct stages like egg, larva, pupa, and adult.
They go through puberty just like humans.
The cells went through 6 generations, because each generation doubles the number of cells (4, 8, 16, 32, 64, 128).

Yes, evolution is a fundamental process that affects all living things, including organisms as diverse as bacteria, plants, animals, and humans. It is the mechanism through which species change and adapt to their environments over successive generations.
They were one of the first organisms to go through cephalizaion (the development of a brain)
No. AIDS is a retrovirus that affects humans, who are eukaryotes. Rhinoviruses cause the common cold. The list could go on.
