Which two factors of a molecule determine whether or not it can cross the membrane? A. Color and weight B. Shape and texture C.
myrzilka [38]
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>

Each of 100 laboratory rats has available both plain water and a mixture of water and caffeine in their cages. After 24 hours, t
olchik [2.2K]

Answer:

C. About 18 percent of the variation in blood pressure can be explained by a linear relationship between blood pressure and caffeine consumed.

Explanation:

Here, r = 0.428

∴ We can say it will give a positive curve, as 0.428 indicates it is a positive correlation.

Though the amount of correlation is low, still it is positive and more than 0.4

So, nearly about 18% of the variation in the blood pressure can be observed by the consumption of caffeine water. As consumption of caffeine water and blood pressure is both increasing so we can say that r= 0.428 will give a positive linear curve.
