To understand the chemical basis of inheritance, we must understand the molecular structure of DNA.
earnstyle [38]

Answer:

C) reductionism

Explanation:

The approach of reductionism is applied to decipher the basic concepts that rule some complex life processes. In this approach, the complex life processes can be interpreted by explaining the physical and chemical structure of involved components and their interactions. DNA molecules store genetic information. Inheritance means the transfer of genetic traits from one generation to the next. Therefore, the chemical structure of DNA is the application of reductionism to understand the chemical basis of inheritance.

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.
