Re: White Moose

Wow, did you think about what you were doing before you killed that moose and one other thing- do you hunt for sport or do you hunt so that you can feed yourself and your family?
- think before you act and please don't post any photos like that on here again- thank-you

A species can't want to die- they will be effected by natural selection and evolution.

Diffusion will still occur but it will take much longer becuse a cells surface volume ratio.
Osmosis will not be affected... in better terms whether or not water will be able to cross the cell membrane will not be affected by cell size.

Re: Exception to Characteristics of Life.

Greetings, I have a bio quiz question that I cant seem to find the answer to and was wondering if any of you gifted individuals could help me out. The question is: What has all of the characteristics of life (ie, grows, reproduces, is made of cells) except does not have the last characteristic, whi...

Re: Plasma Layer

1.Yes water is small enough to get through the membrane and in some cells there are specialized channels through which water can pass 2. Yes there are other things allowed through by the membrane- small nonpolar molecules can pass through such as oxygen but polar or charged molecules can't due to th...

Actually, I need to do a report on a specific invertabrate like a certain breed of jellyfish or something. It still would be good to compare what ever you chose to other invertabrates. That way you will get a better sence for the invertabrate you chose and you will be able to present your topic wit...

I think that it should be left up to the patients. I mean, isn't it wrong to deny a patient any medical procedure? My personal thought is that stem cells should only be used to save lives...not to simply improve the human body. I could accept destroying potential life to save a relative's, but I th...

Re: General Biology

How do each of these factors contribute to natural selection? A. Fertility of individuals in a population is high- more competion over food B. Environmental resources are limited- the ones that can collect it the best and the smaller members of a species would survive C. Not all members of the popul...
