Beginning in the mid 1600's Earth entered into a mini-ice age. 1815 was known as the "year without a summer" and snow fell in ma

ny European countries during the summer months. The year without summer was believed to be the result of a major volcanic eruption, Mount Tambora. Although the exact cause of the mini ice age is unknown, scientists speculate that the low temperatures correspond with A) very low sunspot activity. Eliminate B) the industrial revolution. C) increased greenhouse gases. D) a growing hole in the ozone.

Many plant cells have more than two complete sets of chromosomes in each cell. Explain how this might occur.
otez555 [7]
Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.

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.
