As the ocean becomes more acidic, what is happening to the coral reefs underwater?
a)they are growing out of control and are taking over the ocean.
b)the acid is giving them more color to camouflage from their predators.
c)they are giving the fish around them diseases.
d)they are slowly dissolving, leaving the rest of their food web without a source of food.

The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
