Answer: Option B

The enzyme has changed shape because of high temperature.

Explanation:

Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.

High temperature changes the shape of enzymes.

Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.

Hurricanes form when warm, moist air rises over the water. Cooler air replaces the rising air. Mr. Gaines's class identified that the pressure in the center of the hurricane is decreasing which indicates the storm is getting stronger as the wind increases, i.e., option 3.

<h3>What is a Hurricane?</h3>

A hurricane is a powerful cyclone that is tropical and forms in the Atlantic or Northeast Pacific Oceans.

Surface atmospheric pressure is fairly low in the center of a hurricane. An eye forms in the center of the storm system as it rotates faster and faster. With very low air pressure, it is very calm and clear in the eye.

Thus, the correct option is 3.
