Fundamentals of Physics 10
In the return stroke of a typical lightning bolt, a current of 2.5 ' 104 A exists for 20 ms. How much charge is transferred in this event?

Essential University Physics 3
Explain why measurement standards based on laboratory procedures are preferable to those based on specific objects such as the international prototype kilogram.

Biochemistry 9
It is possible for the codons for a single amino acid to have the first two bases in common and to differ in the third base. Why is this experimental observation consistent with the concept of wobble?

College Physics: Explore and Apply 2
If on a hot summer day you place one bare foot on a hot concrete swimming pool deck and the other bare foot on an adjacent rug at the same temperature as the concrete, the concrete feels hotter. Why?

Biochemistry 9
If the amino acids alanine and glycine react to form a peptide bond, is there more than one reaction product? If so, what products?
