Need, oxygen is not nessicary, oxygen in not essential.
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 answer to this question would be: 14%
Protein will give a calorie about 4kcal/gram. Then, the total calorie of protein from Susan meal would be: 70 grams * 4kcal/g= 280 <span>kilo calorie</span>.
To find the percentage you will need to divide the total calorie diet with the protein calorie. The calculation would be:
protein percentage= protein calorie/ total calorie
protein percentage= 280kcal / 2,000kcal = 14%
Alleles are two genes comes from parents and effects same genetical character
It's a <span>British Shorthair</span> because its hair is grey and it has orange eyes. It's one of the biggest cats.
I hope I helped :D
