Adam wants to decrease his current weight, so he should? a. consume the same number of calories as he burns b. decrease his caloric intake so it is less than the calories he burns c. eat foods from only one food group d. increase his caloric intake so it is slightly higher than his caloric output

B. decrease his caloric intake so it is less than the calories he burns

Explanation:

A calorie is the amount of heat required to raise the temperature of a gram of water by 1°C.

Our bodies require a certain number of calories for us to sustain ourselves. However, if we consume more calories than we are using then this leads to the calories being stored in the form of glycogen or fat.

So, Adam needs to consume a lower number of calories so that he can burn the excess away.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
