The chief reason the equatorial regions are warmer than the polar regions is that

a. the equator is closer to the sun

b. sunlight falls more nearly vertically on the equatorial regions

c. sunlight is reflected by ice and snow in the polar regions

d. there is more CO2 in the air over the equatorial regions

Expert Solution

The shape of the earth is spherical. The line which cuts the earth into half is called equatorial line. The rays from the sun come and fall on the equator directly and make its climate hot and wet. Sun rays that reach polar region will be slow when compared to that of the equator, thus polar region will be cold compared to the equatorial region.

Thus, correct answer is (b).

Using the Chemical Structure of Naproxen, circle or highlight all polar regions of the molecule. Make a reasonable prediction about whether your molecule will be soluble in water or not. Explain your reasoning. If it seems to be borderline in molecular polarity, making it difficult to predict solubility, explain your reasoning and the difficulty involved. Compare your predictions with the solubility information in the literature. PLEASE HELP!!

Using the Line-Angle structure of morphine, circle or highlight all polar regions of the molecule. Make a reasonable prediction about whether your molecule will be soluble in water or not. Explain your reasoning. If the drug seems to be borderline in molecular polarity, making it difficult to predict solubility, explain your reasoning and the difficulty involved. Compare your predictions with the solubility information on the literature.

Because the interior of cell membranes is made of non-polar molecular regions, drugs with acid-base properties are better absorbed by cells when their most abundant form is not electrically charged (not an ion). In which region of the body will phenobarbital be absorbed at the lowest rate? (stomach, duodenum, jejunum). it's not stomach
