Answer:
Stems and root
Explanation:
Auxins facilitate stem elongation while inhibiting axillary bud formation, ensuring apical dominance. The root, branches, and stem and tip all contain them. Hydroxy Acetic Acid is a perfect example. Auxin is indeed a growth hormone that facilitates cell elongation and is formed in the stem tip.

A bacteria is a prokaryotic microorganism that can either be beneficial, or harmful to the body. A virus is acellular, and has no cellular structure, and needs a living host to survive; it causes illness in the host, which causes an immune response. Bacteria are alive and can be treated with an antibiotic if it is harmful to the body. Since viruses are considered nonliving, the virus itself cannot be eliminated, but the symptoms can be treated. Another thing a virus can do that a bacteria can't is genetically program itself into the cells, which means that if you get it once, the symptoms can show up throughout the course of the human's life.

Cell differentiation<span> is how generic embryonic </span>cells <span>become specialized </span>cells<span>. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a </span>cell<span> functions.
