Insects have a distinct set of characteristics which all must have if they are insects. They must have three pairs of legs (even though sometimes they may appear different as larvae, such as caterpillars), a set of mouth parts, and a head, thorax, and abdomen.
The process that allows for the growth and development of a multicellular organism is mitosis
So the answer is A. mitosis
Answer:
In cotransport, a single ATP-powered pump that transports a specific solute drives the active transport of several other solutes. Normally, sodium in waste is reabsorbed in the colon, maintaining constant levels in the body, but diarrhea expels waste so rapidly that re-absorption is not possible, and sodium levels fall precipitously. To treat this life threatening condition, patients are given a solution to drink containing high concentrations of salt and glucose. The solutes are taken up by sodium-glucose cotransporters on the surface of intestinal cells and passed through the cells into the blood. This simple treatment has lowered infant mortality worldwide.
Channel protein is important because it is embedded in the membrane and it also covers the membrane. This is important because the channel must transport the micromolecules and ions in and out of the cell. Carrier proteins are important because the carrier must transport the molecule in and out of the cell.
