Polar bears need to consume as much energy as possible from the parts of animals they eat. from this you can conclude that seal skins and fat have

a) less energy than muscle and internal organs
b) more energy than muscle and internal organs
c) about the same amount of energy as muscle and internal organs
d) no nutritional value

Option B, more energy than muscle and internal organs

Explanation:

During extremely cold climatic conditions (as in the poles of earth), mammals like polar bear keep themselves warm by the assistance of  thick layer of fat beneath their skin.

This thick layer of fat is known as blubber which is also called as adipose tissue. Blubber is found in almost all the body parts except the flukes, flipper and fins.

Blubbers thus are responsible for storing energy and keeping a mammal warm during extreme climatic conditions. Also, they produce and secretes hormones in the blood stream

Hence, option B is correct

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
