I was working through a bunch of questions. But one of them I could not seem to get my mind across.

Of the main processes in embryogenesis, which begins first?
a)Programmed Cell Death
b)Cell differentiation.
c)Cell proliferation.
d)Cell migration.

I don't think it is programmed cell death, nor cell migration. I am thinking between differentiation and proliferation. I know that zygotes undergo cleavage, and that increases the amount of cells, but does not effect the size overall. So perhaps differentiation?

I am not very sure. I anxiously await for your responses, it's getting on my nerves. Smiling Face with Open Mouth Thanks.

It's B, cells have to become differentiated because you start off with stem cells (pluripotent cells) that develop in brain cells, skin cells, smooth muscle cells, etc.

Keep the questions coming, I like these Slight Smile
