Endothelial cells
These cells are found in all the parts of the circulatory system , these are about a cell thick , and composes a wall known as the edothelium , which lines all the blood vessels , i.e. , the arterioles , veins , capillaries , arteries , venules .
Beneath the endothelial cells , there is a layer of smooth muscle cells .
The study is an example of a longitudinal study.
In a longitudinal study, researchers follow a group of people over a period of time and collect data at different points in time. This allows the researchers to see how changes in the participants' behavior or environment (in this case, their diet) may be associated with changes in their health outcomes (in this case, their risk of developing ADHD).
The data from this study could be used to support or refute the hypothesis that certain dietary factors are associated with the risk of ADHD. For example, if the data showed that children who ate a lot of sugary foods were more likely to be diagnosed with ADHD, this would support the hypothesis that diet plays a role in the development of ADHD. However, if the data showed no such association, this would suggest that diet is not a significant factor in the development of ADHD.

Bicarbonate ions in the blood helps in neutralizing the extra acid in the blood and is reabsorbed by kidneys. Excretion of excess H⁺ ions from kidney also helps in regulating the pH of body fluid.
Almost all the proteins acts as buffer because they have charged regions which can bind to H⁺ or OH⁻ ions thus provide buffering capacity to the blood.
Thus, the correct answer is a all of these.

The subjective symptoms that have led Jessica and Mike to presume she is pregnant are:
The missing of her period.
Clothes feeling tighter.
Breast tenderness.
Being nauseous in the morning.
Eating all the time.
Frequently going to the bathroom.

The reason for this is that they are only noticeable by the person that experiences them or by someone that is keeping a close look at that person, like Jessica's husband.
