Bacteria that live in extremely hot water are called thermophiles. If you looked at a particular enzyme in such bacteria, do you think that it might have more or fewer cysteine amino acids than bacteria living at moderate
temperatures? (see cysteine's structure in table 3.2 and consider what this amino acid is often used for in tertiary
structure)

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

the contamination

we are putting to many trash.
