The cygoat is it is during the first two weeks after for relation during prenatal development.
00:26

00:35
So that will be crips afar.
00:37
And then an embryo is the unborn.
00:43
Offspring during the second to eighth week of development.
00:52
So that wouldn't be right for the second part of the question.
00:55
So a would not be a good choice.
00:59
And then b, the first, first cygo, that's the first two weeks when rapid cell division occurs.
01:08
So that would be, again, a good choice for the first part of the question.
01:13
And then the fetus is an unborn offspring from eight weeks...
