roles of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development of an organism? Cell division is needed

of Biology pg.1 The major theories of biology are evolution of natural selection‚ biological classification‚ inheritance‚ cells‚ bioenergetics‚ homeostasis‚ and ecosystems. Evolution by natural selection is a process that occurs over successive generations. Inheritance is a theory of how characteristics of one generation are derived from earlier generations. Cells theory is that all organisms are composed of cells and that all cells come from preexisting cells.

The effect of temperature on beet cell membranes Introduction: A cell membrane of a beet (Beta Vulgaris) is made up of a phospholipid bilayer with embedded proteins and cholesterols. The membrane is responsible for organizing the cell‚ protecting it from the exterior environment‚ as well as responsible for regulating what goes in and out of the cell though it’s protein channels and “selectively permeable” bilayer. (Campbell‚ Reece‚ Taylor & Simon‚ 2006‚ p. 79-80) When this membrane is damaged
