The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to incre
spayn [35]

Answer:

The best answer to the question: The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to increased:___ would be, D: All of the answers are correct.

Explanation:

There is still a lot of debate among scientists as to the exact way in which phospholipids are distributed between the two leaflets of a cell´s plasma membrane, but what they do know is that there are four kinds, and that phosphatidylinositol (a sterol) and phosphatidylethanolamine appear most commonly on the cytosolic, or cytoplasmic side of the membrane. They also believe that it is this particular arrangement which allows the cytoplasmic side of the membrane to be slightly negatively charged and this role will play a major part in a membrane´s ability to generate an action potential. Also, it is known that these negatively charged ends of the bilayer will allow certain proteins, positively charged ones, to be inserted, and connected to it, to become transporters, or mediators in action potentials and normal activities of cells. Finally, since fatty acids and cholesterol are associated with phospholipids, but have a tendency to be attracted to these particular two types, they tend to give the overall structure fluidity, but also permit  the inner leaflet to assume its particular circular shape around the cytoplasm. This is why the answer is D.

When lions prey on a herd of antelope, some antelope are killed and some escape. Which part of Darwin’s concept of natural selec
Rufina [12.5K]

According to Darwin's Theory of Natural Selection, each generation produces more individuals than the ecosystem can sustain. However, not all individuals are identical and phenotypical variation exists.

Due to this variation, some antelopes are better at escaping lions, perhaps due to speed and/or stamina. Thus, the individuals that are slower and thus less fit will be killed and eliminated from the herd. The antelopes with heritable traits that makes them better suited to the environment, will escape and thus, survive and reproduce.

In Darwin's Theory predation is an evolutionary force.

The nurse and the client are using therapeutic communication skills. which statements are true of concrete and abstract messages
Hitman42 [59]
Abstract messages include figures of speech that are difficult to interpret. And abstract messages are best used for persons who are anxious. The explanation behind this is abstract messages contain figures of speech that are tough to interpret. Concrete messages are clear, direct, and easy to understand. Concrete (not abstract) messages are significant for accurate information exchange. Abstract (not concrete) messages necessitate the listener to interpret what the speaker says. Concrete (not abstract) messages are best used for persons who are anxious.
