The answer is c
Because homeostasis is the state of steady internal, physical, and chemical conditions
The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.
Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.
Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.

What is the word that describes the path of the sun, moon and zodiac as they "move" across the sky? Ecliptic is the answer.
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>
