Ashrew requires about 4.2 kcal per day to simply exist. if you add in activity, the shrew needs about twice that amount. which of the following would provide the shrew the highest number of kcal for the least amount of food in grams? a. protein b. vegetables c. carbohydrate d. fiber e. fat

E. Fat

Explanation:

Fats are the derivatives of fatty acids which in turn are the derivatives of hydrocarbons. The breaking down of long hydrocarbon chains by oxidation produces a large amount of energy. Fats serve as a stored form of energy. Oxidation of one gram of carbohydrates provides 4 kilocalories while the complete oxidation of one gram of fats provides 9 kilocalories. Similarly, the oxidation of one gram of protein provides 4 calories. This means that the oxidation of fats provides the largest amount of energy for the least amount of food.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
