An earthworm receives support and shape from its fluid-filled cavity. It has Hydroskelton

Explanation:

The muscle of earthworm encloses with two layers of muscle which is circular and longitudinal. There is fluid cavity between digestive part and muscle. it is called coelom and fluid is coelomic fluid. This fluid work as hydrostatic skeleton.

It provides resistance to muscular contraction. It helps the earth worm to applying the force and change the shape. Mostly hydrostatic Skeleton organism has more or less cylindrical. This type of Skeleton found in soft bodied invertebrates.

Suppose that an adult black bear adds 50 pounds of fat in order to survive while hibernating through the winter. how much glycog

NemiM [27]

Answer: The correct answer would be 112.5 pounds

Explanation:

Let us first covert the pound into grams. We know that 1 pound is equal to 453.59 grams.

Thus, 50 pound of fat = 50 x 453.59 = 22,679.5 grams.

We know that, 1 gram of fat releases 9 Kcal of energy. Thus, total energy produced by 22679.5 grams = 9 x 22679.5 = 204,115.5 Kcal

Glycogen is carbohydrate thus, it will produce 4 Kcal of energy per gram.

Thus, 4 x C = 204,115.5 (where C is the grams of glycogen)

⇒ C = $\frac{204115.5}{4}$

⇒ C = 51,028.875 grams

Using 1 pound = 453.59 grams, we con convert 51,028.875 grams into pounds:

453.59 = 1

1 = $\frac{1}{453.59}$

51,028.875 = $\frac{1}{453.59} x 51028.875$

= 112.5 pounds

Thus, 112.5 pound of glycogen would be needed to produce the same amount of energy as produced by 50 pounds of fat.
