_____ explanations for aggressive behavior include genetic predisposition, high testosterone level and frontal lobe damage.
Answer: Biological Psychological behaviors and diseases are often explained as occurring from environmental causes or biological causes. In this case, genetic predisposition, testosterone levels, and brain structure damage all fall under biological causes for aggressive behavior.
Consider that two individual amino acids react together to form a dipeptide. The resulting linkage in a dipeptide is based on 1)_______ bonds and that dipeptide formation would produce 2)________ as a byproduct.
A dipeptide results when two amino acids react together and is a type of peptide bond. A peptide bond forms when the carboxyl end of one amino acid reacts with the amino end of an adjacent amino acid. This amino-carboxyl bond that forms is called an amide bond, which is the answer to the first blank. When this amide bond forms, an OH is removed from the carboxyl group and an H is removed from the amino group, combining to form H2O or water. This is the answer to the second blank.

How many moles of iron react with 1.75 mol of oxygen gas? The equation for the reaction is: 3 O2 (g) + 4 Fe (s) → 2 Fe2O3
In order to solve this problem, you need to utilize stoichiometry. The chemical equation provides the ratio of the number of moles of iron to the number of moles of oxygen, which can be used to determine the number of moles of iron that will react if all of the oxygen reacts completely. Therefore, set up your dimensional analysis in this way to arrive at your answer: 1.75mol O2 x (4 mol Fe/3 mol O2)= 2.33 mol Fe
