7 0

Answer:

The correct answer is -

1. Adenine - 10%

2. A-T and C-G always in DNA.

Explanation:

1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.

So, Cytosine = 40%, Guanine= 40%

total = 80%

therefore, the A and thymine would be - 100 - 80 = 20

A+T = 20

A= 10, and, T = 10%

2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.

Kamila [148]

Answer:

Can predation result in selection for color patterns in guppies?

Explanation:

Researchers took guppies from their pools that is seen to have pike­cichlid fish (a huge guppy predators) and then implanted it in another pools that is seen to have the killifish (they are not really active predators that prey wholly on the childish and immature guppies). They then estimated to see if the color patterns in the grafted or transferred population undergo some alterations in the course of time.

Eating potatoes with the skin as opposed to without the skin can increase dietary fiber intake. A medium-size baked potato weigh
KATRIN_1 [288]

Answer:

  • <em><u>There are 1.6g more of fiber in the the potato with skin than the potato with flesh only</u></em>

<em><u /></em>

Explanation:

In the internet, you can find that a regular potato (medium-sized) with the skin contains about 4 grams of fiber; and half that is  in the skin , thus a potato without skin contains about 2 grams of fiber.

In other site, I found that the source used to deal with this question states 4.2 grams of fiber for <em>White, Flesh and Skin (173 grams)</em> and <em>2.6 grams for Potatoes, Baked, Flesh Only (173 grams)</em>.

Therefore, using the second reference, the differnce in the amount of fiber, in grams,  for the potato with skin and the potato with flesh only is:

  • 4.2g - 2.6g = 1.6g

The answer is that there are 1.6g more of fiber in the the potato with skin than the potato with flesh only.
