Hello everyone, so let's do this biology problem, but before i get started, i recommend that you do the question yourself i'd come back to see if we got it right or not.
00:10
So hopefully we've done the question yourself now is working together.
00:13
So we're given these true or false, we're given these statements and we want to talk about whether they're true or false.
00:20
So the first statement is fertilization requires mioses in advance.
00:32
And we want to talk about if this is true or not.
00:34
Well, let's think about it.
00:35
So myiosis, we'll know is that process where it forms the gametes, forms the sperms and the eggs, and there's a bunch of alleles swapping and crossing over of the alleles to produce four different dora cells with unique genes, right? but the main point that we want to come at is that bios produces the sex cells that are needed for fertilization.
01:00
So this question is going to be true.
01:01
Because fertilization occurs when the two sex cells, the sperm or the egg, at least for humans, when they fuse together to form embryo.
01:12
So the first statement is true.
01:15
And then, so myosis and germ cells, they ensure that the haploid number of the chromosomes in gametes, right? myosis forms 4 -10 cells and they're haploid gametes.
01:27
So that when the male and female gametes fuse together during fertilization, a diploid zygote, is formed.
01:34
So that is hopefully making the first statement a bit clear.
01:38
And moving on to the second statement.
01:40
So we have miosis makes germ cells of gametes.
01:49
Well, we already know that statement is true.
01:55
It's fault, sorry, because myosis is the formation of gametes.
02:02
And myosis does not make germ cells.
02:06
Rather, myosis is, that's an easy way to look at it that there is already a contradiction in the statement because it states that myiosis makes germ cells when in actuality myosis makes gametes.
02:18
But another way to think of it is myosis is a cell division that occurs in gem cells.
02:23
Rather, myosis one specifically occurs is a cell division that occurs only in germ cells.
02:28
So there's no way that germ cells would be made...
