Cathy and Benito pack the 25 calenders they have not sold into a box . There are 16 desk calenders in the box. If Benito pulls a calender out of the box without looking, what is the probability that that it will be the pocket calender?

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
