stomach villi and blood distribute food
Answer:
I beleive that the answer is C, Not quite sure.
Explanation:
the very basic properties of water
conducts heat
neutral pH
high surface tension
high specific heat
good solvent
how does this help a polar bear, some of it is a stretch but possible benefits
pH - good drinking water, good for marine ecosystem for food
high specific heat - can absorb lots of heat before the temperature rises, polar bears exist naturally in cold environments. (ice) - maybe can tie this in with the natural hibernation cycle
high surface tension - I'm assuming the polar bear walks on the ice at times to get fish
as a good solvent - its probably good that most things dissolve in water, otherwise we would have a lot of floating gunk on top of the water
outside of this, can't give you much more. it has been noted in Shishmaref Village that the ice caps melting is leading to a lack of water in higher mountain areas and polar bears are coming down from the mountain ice cap areas to find food and water
The purpose was to test the idea that the complex molecules of life. in this case, amino acids. could have arisen on our young planet through simple, natural chemical reactions. The experiment was a success in that amino acids, the building blocks of life, were produced during the simulation.
<span>This is a true statement. When a person is not being stimulated but is in the process of becoming tired, they will start to experience almost instant drowsiness. This is why it is important for a person to continually be doing something if they are starting to become tired and are in a dangerous situation. This will alleviate the tendency to start to drowze.</span>
