Instrument used to cut skin
Scavengers – Animals that consume the carcasses of other animals that have been killed by predators or have died of other causes
Hypha – A filament of fungal cells
aquaporins – water channel protein in a cell
Examples of epithelial tissue – skin, tissue lining inside and surface of organs
Instrument used tо cut skin
inductive reasoning – Starts as facts and works towards general conclusions (science). It is the process of finding rules.
Constants – variables or conditions that are kept the same; they are important so that you know the IV changed the DV
contractile vacuoles – A membranous sac that helps move excess water out of the cell.
