So that they can adapt to the situations that surround them in their environments.<span />
Hormones can be transported in blood in dissolved form or bound to a transport protein or serum carrier.
...The enzymes in the shrimp denature when exposed to the higher heat. Enzymes denature at high heat. That's what kills you when you're fever is too high, your enzymes denature, which means they are deformed/ become the wrong shape. Since the activation sites on enzymes are very sensitive to shape, they wouldn't work anymore. The cold doesn't denature enzymes however. They don't work as quickly but they still retain their shape.
A frameshift mutation is a mutation which changes the sequence read and transcribed by the ribsome, also presenting the possibility of coding for the wrong amino acid. You can have two types; frameshift substitution or frameshift deletion. In a substitution, a mutation occurs, adding a new basepair and shift the sequence read to the right. In a deletion, a mutation deletes a base pair and moves the sequence read to the left.
frameshift substitution: CGG TAT
frameshift deletion: CTA T
