CAN SOMEONE HELP ME!! Now make a list of questions to guide you in your research. You should be able to answer these questions in your paper:

What characteristics do these animals have that help them survive the temperatures of their environments?
What kind of nutrition do these organisms need?
Do they have characteristics that help them find and capture food?
Do they have ways to sustain themselves if the availability of food or water is limited?
What natural defenses do these animals have against predators?
Do they have characteristics to protect their young?
How do genes play a role in the adaptations these organisms developed?
Are these two organisms suited to live in each other’s environments? Why or why not?
Write at least two additional questions to help in your comparisons.

The ANIMALS I USED ARE:
1.Phillips' kangaroo rat
2.Artic fox
Oh, and the first question is answered.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

maybe because its impossible for balloons to lift a whole entire house.
