Phospholipids are a class of lipids that contain a phosphorus atom. They are structural components in cell membranes. They have an amphiphilic ( having both hydrophobic and hydrophilic) characteristic and thus they can form a lipid bilayer. Their structure consists of two hydrophobic fatty acid "tails" and a hydrophilic "head" consisting of a phosphate group.

Answer:

c. Physical adaptations to the environment drive the distribution of all three species in the wild.

Explanation:

Options A and B refer to competition between species. The experiment was about the colonizing ability of the three species, and not the interaction among them. So these two options are not correct.

Option D states that species A is better adapted to the upper intertidal zone than the middle or lower. But the table shows that species A is equally adapted to colonize upper and middle intertidal zone, and less adapted to colonize lower zones.

The correct option is C. When these competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species. In the exposed example,  the three species coexist in the middle and lower zones, which means that they probably have different niches and got adapted to living to their environments. This adaptation to different conditions is what leads to their distribution.    

In the exposed example, species A and B can live in the upper intertidal zone, where species C can not live because they can not tolerate environmental conditions. The three species can live in the middle zone, but still, A and B are more adapted to this area than C. Among A and B, B is the most adapted to living in the upper and middle zones. Species C seems to be very adapted to live in the lower intertidal zone, where species A and B can also live, but are less adapted to this area, probably due to environmental conditions or due to their vulnerability to predation. In this last area, species A is less adapted.

Answer:

questions:

Should I or can I eat salty foods?

Do I have to check my pressure immediately?

Do I have to follow a balanced diet?

Is it good to do physical activity?

Do I have to worry about the signs of eye flickering and headache?

Explanation:

Blood pressure is regulated by endogenous mechanisms, although these sometimes fail and it is necessary to take drugs to reduce high blood pressure, an example of which is beta-blockers.

Blood pressure is also regulated by diets based on low sodium consumption, necessary calories and with great contributions of nutrients since cardiac or cardiovascular health is also essential in the face of possible formation of atheroma plaques.

The increase in blood pressure with the appearance of atheroma plaques is very common, and it is also the two most frequent causes of AMI (acute myocardial infarction)

Anton [14]

It illustrates the cycling of matter, just like in a natural ecosystem.

Option D.

<h3><u>Explanation:</u></h3>

The natural stable ecosystem is defined as the ecosystem which has the members doing their part of job and each and every member contribute to the stability of the ecosystem by completing food chains.

Here in this bottle ecosystem the boy put the stones, rocks, water which gives proper nutrition to the growing plants and animals which are also introduced by the boy. The plants produce oxygen and consume carbon dioxide whereas the animals consume oxygen and produce carbon dioxide. Thus the cycle is maintained and stability is achieved.
