In catalase chemical reaction of hydrogen peroxide, the enzyme will change hydrogen peroxide into water and oxygen. In this case, hydrogen peroxide will be the substrate. If there is more substrate available, then the chance for the enzyme to bind to the substrate will be higher, thus the reaction speed will be higher in solution with higher hydrogen peroxide
When a muscle cell contracts some myosin heads bind to actin molecules as other myosin heads release from actin molecules.
Muscle contraction occurs when the thick filament and the thin filaments slide over one another in a series of repetitive events.
The answer is 6 per m2.
A population density is the number of animals per 1 m2.
So, this problem can be solved by using a proportion:
If 60 raccoons live in 10 m2, how many raccons will live in the 1 m2.
60 raccoons : 10 m2 = x raccoons : 1 m2
60 raccoons : 10 = x raccoons
x raccoons = 6 raccoons
Thus, the population density is 6 raccoons per m2.
Answer:
D
