Answer: The correct answer is-

b.the hydrocarbon tails.

A phospholipid molecule comprises of a head group (that contains polar phosphate molecule) that is hydrophilic ( water attracting groups due to formation of hydrogen bonding or ionic bonds with water molecules) and two tails of fatty acid ( which are hydrophobic that is water repelling groups).

In this question, a single layer of phospholipid coats the water in a beaker. This means that head group of this layer is in contact of water ( present in the beaker) and the two fatty acid tails of hydrocarbon ( that are water repelling) are facing air.

Thus, option b) is the right answer.

The part of the phospholipid molecule that will face the water, as it is labelled to be hydrophilic would be the polar phosphate group. The correct response would be A.

Which nucleic acid is pictured on the right? Justify your answer.
alukav5142 [94]

Answer:

Nucleic Acids:

- Uracil

- Adenine

- Guanine

- Cytosine

Explanation:

Since we only have one strand shown, I'm going to assume it is RNA. Both DNA and RNA have nucleic acids, but RNA has 1 different nucleic acid; it replaces Thymine with Uracil. So the 4 nucleic acids are uracil, adenine, guanine, and cytosine.

If the picture shown is a cross-section of DNA, then our 4 nucleic acids are adenine, thymine, guanine, and cytosine.

Which of the following locations will be relatively warmer during summers, and why? An inland location, because water heats up f
Katen [24]

Answer:

An inland location, because land has lower specific heat than water

Explanation:

The specific heat is a measure of how much heat must be supplied to warm up a substance by a certain number of degrees.

Water has a much higher specific heat than land, so it takes much more heat energy to heat up a given mass of water compared to the land.

To say it another way, the specific heat of land is much less than that of water, so it doesn't take as much heat energy to warm up the land.

Thus, an inland location will be relatively warmer during summers.

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.
