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

female eggs were to be fertilized in a lab and given a cocktail of growth hormones.

This structure, then, can organize the formation of a membrane boundary around itself, so it can make a body of

Beautiful that's what I like to hear.

(Laughter)

Teachers help to form the minds of children.

The universe cooled, allowing quarks to bind into groups of three, forming baryons.

If you hit it with a neutron, it's going to fission and split into two pieces, two fission products.

And this girl calls herself Tinker.

And the germ cells, we've learned already, these are the ones that produce gametes.

A raid by the Killer Blade Army of Dongranguk!

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

Eventually D.N.A. replaced R.N.A. as a more efficient replicator. Other molecules, lipids, formed tiny bubbles.

We'll talk about how that happens when we talk about meiosis or mitosis, that when I generate my sperm cells, sperm cells essentially takes one instead of having 23 pairs of chromosomes in sperm, you only have 23 chromosomes.

Let me do that Y chromosome in a separate color.

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

You working up your crew psychology report?

And there you have it.

The shape charge.

It's not just any cell in the body.

This is a fourth alternative that you are soon going to have.

Organic matter is formed by large molecules.

The men form a society.

Having lemonade.

Such a waste of talent.

So here is what the hippocampus looks like after forming a fear memory, for example.

I'm adding up the little x sums.

And this is where the system gets really interesting.

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.

Well, the result has been very good.

A drug is made up of a small molecule of hydrogen, carbon, oxygen, nitrogen, and a few other atoms all cobbled together in a shape, and it's those shapes that determine whether, in fact, that particular drug is going to hit its target.

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

I am fluent in over six million forms of communication and can readily...

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.

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

People form society.

They start pushing apart so now I had two centromeres.

Now, this is happening in two cells, of course.

They're identical in every single way.
