Problem 58P CALC A lunar lander is descending toward the moons surface. Until the lander reaches the surface, its height above the surface of the moon is given by y(t) = b - ct + dt2, where b = 800 m is the initial height of the lander above the surface, c = 60.0 m/s, and d = 1.05 m/s2. (a) What is

Aquaporins exclude passage of hydronium ions (H30+). But recent research has revealed a role for some aquaporins in fat metabolism, in which they allow passage of glycerol, a three-carbon alcohol (see Figure 5.11), as well as H20. Since H30+ is much closer in size to water than is glycerol, what do y

The four core histones are relatively small proteins with a very high proportion of positively charged amino acids; the positive charge helps the histones bind tightly to DNA, regardless of its nucleotide sequence.
