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.

Summarize variations in climate among three major zones as you travel south from the equator toward the South Pole?
Ainat [17]
Equator area: closest to the sun and hot and humid due to the mass evaporation from the excess heat. 

Mid equator/south pole: somewhat mild, colder, probably mid-humid, depending on which end of the midsection you're going for

South Pole: cold and dry. Cold because it's naturally far away from the sun (like the north pole) and dry because there isn't significant water evaporation here and any that may form crystallizes into snow and ice.

What did B. F. Skinner believe drove one's behaviors? (Site 1)​
balu736 [363]

Answer:

Environment

Explanation:

B.F Skinner was of the belief that the environment of a person drove or influenced his behavior. His opinion was that human beings have a particular way of behaving which requires special kinds of responses and that as this goes on, humans will adapt and start behaving in a certain kind of way.

He strongly believed that because we learn things differently and in different environments, that is why there are differences in human behavior and one's environment can shape his personality.

UkoKoshka [18]

Answer:

Option A, shared their data with colleagues to obtain feedback on the work.

Explanation:

All researchers prefer to share their findings with their peers or other researchers working in the same field to get their reviews. This step is very essential as it makes the research authentic and removes the flaws that would have otherwise missed by the researcher.  

Peer reviewers also give useful suggestion to further modify one’s research study based on their experiences.  

Hence, option A is correct

Luden [163]

Answer:

The scaling exponent will be 0.75

Explanation:

According to a famous article by Max Kleiber*, the scaling of the metabolic rate or energy consumption for mammals Pmetab (measured in kcal/day) with the body mass Mb (measured in kilograms) is  P metab = 70 Mb^0.75 .

What is the scaling exponent (the quantity x in a scaling law A = cMbx) for the specific metabolic rate as a function of the animal’s body mass?

he scaling of the metabolic rate or energy consumption for mammals P=kcal/day

Mb=body mass in kilograms

Comparing

P metab = 70 Mb^0.75 .

with A = cMb^x

the scaling exponent will be 0.75

metabolic rate is the energy(in kilojoule) consumed at rest. it accounts for the highest amount of energy a body consumes daily
