Can antibody diversity in humans be explained solely by V(D)J recombination? Why or why not?Several proteins must work in a coordinating fashion to achieve V(D)J recombination. Which is responsible for adding nontemplated nucleotides to the V-D and D-J joints of Ig heavy chains?Recognition spacer sequences are separated by how many base pairs?If a given B cell is found to be potentially reactive to self-antigens, can the cell make an effort to correct that flaw, or is it destined for eventual removal by apoptosis?

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
