Abstract:
In the broadest definition, a pesticide (from fly swatters to chemicals) is a substance used to eliminate a pest. Newer insecticides are much safer to the environment, humans, and nontarget species. These insecticides are able to target physiologic differences between insects and mammals, resulting in greater mammalian safety. This article briefly reviews toxicity information of both older insecticides such as organophosphates, carbamates, permethrins, and pyrethroids, as well as some newer insecticides.

Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during...
