I have to have this done for tomorrow (I all ready got an extention:innocent:), and I just cannot wrap my head around it. I've read and reread the chapter but I just can figure out the answers to the questions. Bio is definately not my thing.
I've only answered 5 of the questions so far. They are just so confusing to me (yes, I am a complete moron when it comes to science and algebra. I freely admit it.)
So if anyone can help me, please do! Here are the questions (there are a lot of them).
A.) Why do you think the cylce of some types of cells is faster than others? Explain your answer. (I have no answer because I don't/can't think.)
B.)A parmecuim expels water when it is in fresh-water. What can you conclude about the concentration gradient in the organism's environment? (I can't conclude a thing.)
)1. Describe how a cell's surface area-to vollume limits its size. (I *sort of* have an answer for this one, but I'm not sure if it's right.)
2.) Why is it necessary for a cell's chromosomes to be distrubted to its daughter cells in such a precise manner.
A: Chromosomes need to be distributed to the daughter cells so precisely because the daughter cells need the the genetic information in the chromosomes so they can carry out the same cellular processes and functions of the parent cells. (Does that make any sense?)
3.) Relate cells to each level of organization in a multicellular organism.
4.) In multicellular organisms, describe two cellular specializations that result from mitosis.
5. At one time, interphase ws referred to as the resting phase of the cell cycle. Why do you think this description is no longer used? (I hate the questions that ask what I think- I don't think, I have no opinion when it comes to this stuff. I am way too confuzeled for that.)
6. Make a table sequencing the phases of the cell cycle. Mention one important event that occurs in each phase. (What kind of table????)
There's actually 7 more questions that I have to answer too, but I *think* I can figure those out by myself. Hope so anyway. If not, will somebody please just smack me over the head with whatever's handy (a stick or a fish, whichever you prefer) and put me out of my missery?
