Why do cells divide?

You have the internet. Ask it. It takes 30s. You’ll be pleased you found the answer yourself; trust me.

Lol. Evil teachers.

Because they can.

What a sloppy question.

Cells divide to make more cells. Specific cell types may need to increase surface area to facilitate diffusion (e.g., capillaries). “Volume” and “ratio” are such general concepts that I see no way to effectively answer the rest of this question.

Consult your lecture notes. It seems like your teacher wants you to parrot back some piece of information that was fed to you rather than to really think about cells, since there is no way to answer this question with this amount of information in the question stem. You have my sympathy.

Yep, crappy question. Did you quote it right? Why do you think it’s useful to have others do your homework, anyway?

If you don’t have it in your notes and you can’t find it in your book, check out this site. It will lead you to the answer eventually and may do you good by reinforcing other things your teacher has covered.

Because they haven’t learned yet to multiply?

Watch out @gailcalled. When I talk like that I get threatening letters from the mod team.

@pdworkin: I waited a bit and noticed that all of the answers before me were a bit…uh…sharp. Look out window now towards SE and see Jupiter and the waxing moon. Gorgeous.

Alas, it is cloudy, but my dog and I have had a fine walk.

@pdworkin : Odd. They are both ablaze in the sky here.

@gailcalled- Looks great from Sactown. Nice clear sky here. I enjoyed the walk through the park with my dog looking up at the sky. Toyed with the idea of whipping the old 10” out (reflector, 10” reflector. God. Quit thinking those dirty thoughts.) when I got home but it’s too damn chilly out there.

I used to have a nice telescope, and a non-light-polluted home with a deck from which to use it. Alas, no more.

@pdworkin- Too much light pollution where I live as well. But if you wanna look at the moon or planets when close to opposition it’s not much of a concern.

Oh, we were way in the boonies, and the Milky Way could light one’s way at night. Sorry to get so far off topic.

I misread. Thought you wrote light-polluted home.

Jealous.

Well it’s no longer my home, the ex-wife enjoys it, not I.

I really wish there was an option to “Flag as… trying to make me do their homework.”

Just flag it as “Something else” and write “trying to make me do their homework” in the box. Problem solved.

Typing that out all the time gets tiring. ;)

Ok, so, yea, I was just trying to be funny.
