If a plant cell has a lower water potential than its surrounding environment and if pressure is equal to zero, is the cell hypertonic or hypotonic to its environment? Will the cell gain water or lose water?

Have scientists figured out what kind of animals feel the pain? [not just stimulus]

for e.g does a plant, ant, chicken, fish, cockroach feel pain?

I live in Central Indiana and my son found this huge caterpillar yesterday. It's 5 inches long and an inch thick, and it's mainly dark brown in color. It has a light pink face and strange similar colored back end. It also has some hair, but not really thick, and also four orange spines (might sting) towards the face and one in the middle towards the back. We really want to keep him and see what he turns into but I can't find out what he is. Serious answers only please. Thanks!

I find this interesting. I always thought we yawned to get more oxygen to the brain. Do you agree that it is to let others know we are tired so that we all sleep at the same time and get up at the same time? This may be for safety reasons back when we lived in the wild?

Hi Bill,
Why do we yawn? And why does it seem contagious?
--Sleepy Ruminator

Dear Sleepy Ruminator,
Of course, yawning seems to be a very old form of behavior. It seems to be programmed deep in our brains. I've seen dogs yawn, and it makes me want to yawn right along with 'em. When your best canine friend is opening his jaws wide and shaking his shoulders, you can bet that he's not anxious to go outside and play or go for a long old walk. Modern wild dogs in Africa live in packs. They seldom stray off on their own. A yawn is a dog's way of telling her buddies in the dog pack (or you as her keeper) that she's ready for some doggie z's.

Having lunch today, one of us had a baked potato and the other a plate of chips. Now I know that the baked spud is far better for you as a slow release energy food but if the chips are just chopped up potato why are they so much worse for you?

Is is just because they are fried?

Also - as a side question - what exactly do nutrients do for you?
