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.

GenaCL600 [577]

Answer:

Earth has been our place for many years. all inhabitants on earth are causing great destruction. along the way we tried to resolve issues yet some we couldn't figure out. the one we couldn't figure out had made a great impact on our world today. Just how do we stop it? Many ways actually, taking pollution for example. pollution is a great cause for why earth isn't as lively as before. along the years we've polluted 92% of the earths air. causing us to breathe unhealthy air. We can easily fix this problem with finding new ways to get somewhere like riding a bike or taking an energy efficient car. Therefore, we humans have change the world dramatically by doing good things and bad things, too. but in the end we are the ones causing earth to nearly give up, so we can also be the ones to let the earth forgive.

hope this helps you out!

Athletes and physically active people have increased needs for
STALIN [3.7K]
They have increased need to carbohydrates, protein, water and iron.

Carbohydrates is the primary source for energy and active people apparently need more energy for their daily activities.

Protein helps build muscles, even though they only need a small amount more of protein than normal people, they still require protein for muscle buildings.

Water has to be needed as they may excrete more sweat by active activities in the day time. Water can also help remove waster material from body.

Iron helps the production of hemoglobin, which is in the red blood cells that help transport oxygen. As they exercise more, they need more oxygen supply for respiration, therefore there is a need for iron supply.

Alenkinab [10]

Answer:

a. True

Explanation:

Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele <em>It </em>was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of <em>It</em> for each generation was determined.

The result of this study showed that<em> lt/lt </em>died without reproducing, whereas, individuals with genotype <em>+/+ </em>were normal.
