In a previous unit, you completed the "Case One: Rookie Training" game. Now, see what you've learned! Choose one of the other cases. You can play "as guest" if you don't want to register. The "Walkthrough" link in the top right hand corner of the window can help you determine what to do as you work through the case.

What kinds of molecules can pass through the cell membrane without any problem?

Aquantity of gas has a volume of 18 m3 and an absolute temperature of 225 k. when the temperature of the gas is raised to 380 k, what is the new volume of the gas? (assume that there’s no change in pressure.)

Which survival need shortage would most affect articular cartilage's ability to rebound after joint compression, and why does it have this effect? which survival need shortage would most affect articular cartilage's ability to rebound after joint compression, and why does it have this effect? nutrients, since the majority of cartilage is made out of polysaccharide glycosaminoglycans (gags). water, since it makes up to 80% of cartilage's content and cushion articular bone surfaces. normal body temperature, since higher temperatures would slow down necessary biochemical reactions. oxygen, since cartilage cells receive this gas directly from nearby blood vessels?
