1) Describe the difference between: autotrophs, heterotrophs, chemotrophs, and phototrophs.
Autotrophs are organisms that can synthesize their own energy supply out of inorganic matter, such as light or chemicals Heterotrophs are organisms that cannot synthesize their own energy, so they receive their energy by consuming organic matter, such as plants or animals. Chemotrophs are organisms that acquire energy an oxidation-reduction reaction of organic or inorganic chemicals; this meaning the electron donors of that environment have become oxidized. Phototrophs are organisms that solely use light as the energy source to produce nutrients, such as the process of photosynthesis.

2) Describe purpose and steps of binary fission. Also, explain how binary fission is described mathematically and graphically and identify the two interchangeable terms used to describe this growth.
Binary fission is the process in which a cell grows twice its normal size, and then the cell divides in half to produce two daughter cells. This process is carried out by unicellular organisms because it is their only way of reproduction. The cell begins this process by replicating the cell’s DNA, and the duplicated chromosomes attach to the cytoplasmic membrane or microtubules. Once attached, these attachment sites push the chromosomes apart to expand the entire cell body. The cell now produces a new cytoplasmic membrane, and along the mid-line of the cell a septum begins to form. Upon completion of the
