It means the system absorbs energy from surrounding objects; usually, but not always, involving heat
Before I get to the answer, I would recommend that you post biology questions under the biology category. You should get your answers more quickly that way :)
There are two things that happen before a parent cell divides:
1) DNA in the nucleus of the parent cell must replicate (this happens in the S phase of the cell cycle). If you're looking for a single answer to your question, then this is probably it.
2) Also, the cell must grow and some organelles (like the mitochondria) must also replicate before the parent cell divides. If organelles like the mitochondria did not replicate, then you would eventually end up with daughter cells that don't have enough mitochondria to support themselves.

( sorry if this doesnt help it really didnt make sence to me!)
Answer:
I and IV are the correct answers
Explanation:
Cl₂
Explanation:
The gas with the highest molecular mass will be considered the heaviest of all of them.
To solve this problem, we must calculate the molecular mass of the given gases;
O₂ CH₄ CO₂ and Cl₂
O₂ molecular mass = 15.9998 x 2 = 32g/mol
CH₄ = 12 + 4(1) = 16g/mol
CO₂ = 12 + 2(16) = 44g/mol
Cl₂ = 2(35.5) = 71g/mol
The heaviest of the gases given is Cl₂ because it has the highest molar mass compared to other gases.
