1. The pulmonary circuit is supplied by which ‘side” of the heart? The systemic circuit? The right atrium

Most enzymes work best at body temperature, higher temps will cause the enzyme to no longer work properly

3. State the name and structure of the functional group for each type of biologically

A chemical reaction involving the transfer of electrons rather than molecules is classified as a Redox reaction. A reaction involving the loss of electrons is called Oxidation, and a reaction involving the gain of electrons is called Reduction. Oxidation and Reduction always occur together, as one reactant loses electrons, and the other gains them. This exchange often effects the physical states of molecules, as their solubility is changed with their charge.

1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points)

Cellular respiration: C6H12O6  +  6O2 →  6CO2  +  6 H2O  +  36 or 38 ATP

The cephalopodor octopus is a marine organism that inhabits many diverse regions of the ocean. Its food source consists of crabs, small fish, clams, mussels and other marine animals. The octopus is a predatory animal and has developed many skills to aid in its survival in the environment it has adapted to.

Some of the similarities that are between both is that the digestive system is some what similar to the human digestive system. How that works is all the food goes down in the mouth first and then goes to the Crop, in which is the stomach of the worm. It stores there for a bit until it goes to the Gizzard in which that would break down the nutrients that the worm needs in its body. In which the waste will soon leave out of the body for both of them. They also have pharynx in which is part of the throat and the esophagus in which is the part that carries the food to the stomach.

Coelomates have an enclosed body cavity, which means advance muscle structure, enhanced locomotor capabilities, and more structural integrity.

The law proves that natural selection is necessary for evolution to occur ("SparkNotes: population genetics," 2014). The conditions set up by the Hardy-Weinberg Law allow for variability (the existence of different alleles) and inheritance, but they eliminate natural selection ("SparkNotes: population genetics," 2014). The fact that no evolution occurs in a population meeting these conditions proves that evolution can only occur through natural selection ("SparkNotes: population genetics," 2014). The Hardy-Weinberg Law allows us to estimate the effect of selection pressures
