Answer:
D. Heart contraction and pulse are connected with one another.
E. Atrial diastole and ventricle diastole.
Explanation:
Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.
In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.
I think it’s T lymphocytes?
It says: T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, which control the entire immune system....
D. Polarity and size.
<span>The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of a lipid, and is highly soluble in the nonpolar environment of the lipid bilayer. You saw, in the animation above, the cholesterol freely passing into the hydrophobic environment of the membrane. Cholesterol distributes freely in the membrane and then some fraction will dissolve in the aqueous environment of the cytoplasm. Water, on the other hand, while polar, is small enough to cross the membrane at a slow rate. Note that specialized transport proteins in certain cell membranes can provide a channel for the water, greatly increasing its rate of crossing the membrane. The lipid bilayer is much less permeable to the ion, because of its charge and larger size. As a general rule, charged molecules are much less permeable to the lipid bilayer.</span>
Here is the answer to this question:

According to the </span>RNA<span> World </span>Hypothesis<span>, life later evolved to use DNA and proteins due to </span>RNA's<span> relative instability and poorer catalytic properties, and gradually, ribozymes became increasingly phased out. The ribosome, a large molecular machine that drives protein synthesis, is a ribozyme.

Answer:
Answer is below.
Explanation:
First of all, it would be much darker the deeper you go. On the surface, the light from the sun touches the ocean, making the ocean look like a light blue. However, if you dive down even deeper, you will find a darker blue, and later nothing (the sun won't touch the deep parts of the ocean, so all you would see is darkness). The short answer to this is: It's lighter around the surface, and darker the deeper you dive down into the ocean.
