a. Yes, all the time for growth and replacement.
b. No, you are born with so many cells and that's it.

All cells technically reproduce asexually. Cell division of any kind is asexual, though certain single-celled organisms can share DNA (but between each other - they exchange plasmids and then each of the two separate cells divide on their own). Human somatic cells go through mitosis on a regular basis (replicating and dividing to creat two identical diploid daughter cells), though certain types more often than others (epithelial, hair follicle, and bone marrow (blood-cell producing) cells most oftne, neurons least often). Gametes (sex cells) are created through mitosis (replication and division to create four non-identical daughter cells), but the "sexual" part of reproduction comes when two gametes from two individuals combine to create a diploid zygote that is genetically different from either of the parents.

i became thinking approximately this consistent with week or 2 in the past. i became thinking approximately how interior the destiny whilst we are figuring out on the genes of babies earlier they are born (like interior the action picture Gattaca) then we can start to tinker with humanity and reproduction and that i will guess that finally we can come to a selection to make humanity one gender and reason ourselves to be able to reproduce asexually. and such as you mentioned, there will be MANY advantages of one in each of those society. i think of one gender that reproduces asexually is the way forward for humanity. superb desires :)

yes cells reproduce and multiply within your body all the time. so a some people have even theorized that your cells only reproduce like 13 times and then you die but have no sufficient evidence to prove this happens...

a.yes all the somatic cells in the body divide by mitosis, ie the asexually

a, if you didn't, a cut would never heal and most of us would be dead, since blood cells die pretty fast.
