How much do landscape features on the moon change overtime compared to landscape features on Earth? Explain your
answer.

Answers

Landscape features on the earth changes constantly because of the movement of crust, erosion by water and wind, and living organisms.

The surface of the moon changes slowly because none of these factors are active. In other words, the moon is “dead” geologically with little tectonic activity. The moon also does NOT own an atmosphere like how the earth does. There is no life on the moon.

You and a group of friends are spending your vacation hiking through the mountains. It is cold in the mountains. You will be expending a lot of energy while hiking and you will need plenty of energy to help keep you warm. You should pack foods high in ________ to provide the most energy or kilocalories per gram of food. A) carbohydrates B) lipids (fats) C) proteins D) sugars

Answers

Answer:

The correct answer will be option-B (fats or lipids)

Explanation:

The oxidation of fatty acids provides the most abundant energy that is 9 kilocalories per gram of food as compared to proteins and the carbohydrate which provides only 4 kilocalories per gram of food.

If a person wants to go hiking then, the person would keep the food rich in fatty acids which will provide a high amount of energy and a large amount of heat through the process of respiration.

Thus, Option-B is the correct answer.

C. proteins
