Blank #2: proteins with shared ancestry that have the same function, but are found in different species, are homologs (homologous proteins). Blank #3: phosphorylation is a reversible modification of a protein. Blank #4: the average charge on a amino acid below its pI (isoelectric point) will be positive. Blank #5: the hydrophobic effect increases as the number and strength of hydrogen bonds between water molecules increases.

Pоpulаtiоn grоwth is аffected differently in dense versus spаrse populations. When female bats raise their offspring, they form "maternity colonies" that are densely populated. In these populations, the female bats are so tightly packed together in one area that their bodies touch one another. Mites, a common parasite of bats, thrive in this type of environment because they can easily move from host to host. What might you predict would happen to the mite infection rate once the maternity colonies naturally break apart? The parasite population will ________.
