Answer:
velocity = 3 m/s
Explanation:
kinetic energy = 1/2 * mass(kg) * velocity²
Using the formula:
18 = 1/2 * 4 * velocity²
9 = velocity²
velocity = 3 m/s
The statement that suggests that the shape of an enzyme determines its function, would be the fact that enzymes are specific to certain substrates, depending on the particular shape of an enzyme it can allow binding to specific substrates and allow for catalyzing that corresponding reaction.
When the body becomes dehydrated, a chemical signal is sent that causes nephrons in the kidneys to absorb more water and excrete more salts. This is an example of a <em>D Feedback loop</em>.
