Which term is used for trails of severely burned material, edged by relatively low or
Anna [14]

Given what we know, trails of severely burned material, edged by relatively low or  unburned materials indicate the flow of an accelerant, meaning that they represent pour patterns.

<h3>What are pour patterns?</h3>
  • It is a pattern that forms when an accelerant is used to ignite a fire.
  • This pattern includes heavily burned material surrounded by less burned material.
  • This is not a pattern that occurs in nature.
  • This pattern is always due to the use of an accelerant that more severely burned that which it came into contact with.

Therefore, we can confirm that the scene described in the question corresponds provides evidence that corresponds to a pour pattern that is left behind when an accelerant is poured to ignite a fire.

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.
