Solution:
The most appropiate unit of measurement fro most types of cells is CD4 counts are measured in cells per cubic millimetre = cells/mm3. A cubic millimetre (mm3) = mm3 = 1 mm x 1 mm x 1 mm.
This is the required answer.
All of the above are needed. Nucleotides are the basic building blocks of new DNA, ATP energy is needed because replication is an active process, and enzymes catalyze the reactions needed to carry it out (e.g. helicase to separate the strands to be replicated, DNA polymerase to build the new strands, and ligase to "glue" the fragments together).
The consumer is the bird because it is getting its energy by eating the fruit from the bush.
sorry I don't know maybe I should try
