Question
Chapter 47, Problem 13PIAT
Summary Introduction
To analyze:
The hypothesis that the pill affects the normal hormone secretion and signaling in the body.
Introduction:
The pill’s mechanism was confirmed by the scientists by measuring the plasma hormone levels before and after the use of the pill. Single asterisk (*) signifies P < 0.05, double asterisks (&) signify P **lt; 0.01, and triple asterisks (&*) signify P **lt; 0.001.
The given statistical data represents a drop in the level of all the four hormones after the pill ingestion. The pills affected the hormone signaling drastically, thereby decreasing the levels of the hormones. In all the four bar graphs of the hormones, the hormone levels drop.

10. Your instructor will give you 2 amino acids during the activity session (video 2-7.
A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids
using the same colors as in #7. Do not color the bonds in the backbone of each amino acid.
B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could
occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds
in the backbone of each amino acid.
C. Position the two amino acids on the page below in an orientation where the two R groups
could bond together. Once you are satisfied, staple or tape the amino acids in place and label
the bond that you formed between the two R groups.

I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format)
Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
