That's the egg, and we all know how this story goes.

And this girl calls herself Tinker.

In the case of a male, these would be sperm cells.

So that's a gamete and this is a gamete.

That's their own stupidity. I should've been there.

Let me do that Y chromosome in a separate color.

(Bugle sound)

The absent tea landlady.

One of them said a man is house sitting for his grandmother.

You haven't?

In the tsunami, in the victims. In the depth of things.

Well, the result has been very good.

So that very first cell that was essentially my mom's egg fertilized by a sperm cell from my father, that was a zygote, and as soon as it's successfully fertilized, it has 2N, or it has the diploid number of chromosomes in the case of humans, which I believe I am one of them.

You're not unscannable, are you?

There is now a new career path called stool donor.

And the frogs that are exposed to atrazine, the testes are full of holes and spaces, because the hormone imbalance, instead of allowing sperm to be generated, such as in the testis here, the testicular tubules end up empty and fertility goes down by as much as 50 percent.

Just as an aside, this unification, this fertilization that occurred from this sperm cell to this egg cell, so it essentially penetrates into this egg cell and it creates this zygote, which is a fertilized egg cell from my mother, and this contains all DNA from both my father and my mother.

There could've been 200 to 300 million other sperms in that race.

And this is where the system gets really interesting.

You know what I heard you said once? You said, Them kids are all punks. You can't trust a thing they do or a word they say.

Father is away from home.

Unscannable! No!

Something that's, say, half animal, half human, would be an impossible entity.

My father's sperm somehow met my mother's egg, and they fused.

Where we left off after the meiosis videos is that we had two gametes.

It's not just any cell in the body.

No need for birth control, Doc, are you sure about that?

John, John, I looked at your chart.

Peter is not in now.

Father is away now.

Missed Calls

Mr. Mulwray.

Often, the oil we find now is heavy or sour crude, and is expensive to refine.

In the past, usury really meant any kind of interest, but now in our current cultural context we associate it with just an unreasonable level of interest and that threshold might be different for some people.

Let me draw the sperm.

In the name of the Father, the Son and the Holy Spirit.

So this very first cell that was created from this fertilized egg, this is called a zygote.

I'm off my blessed blooming chump.

And I'll draw the sperm much larger than it is normally relatively to the egg.

Difference human Neanderthal is sperm and testis, smell and skin.

The world remains a rich tapestry.

Away

Out of office reply active

The walls of the egg then become impervious to other sperm so that only one sperm can get in, but that's not the focus of this video.

I think he's immortal. I think he's an alien from another world.
