Question
Chapter 43, Problem 11PIAT
Summary Introduction
Introduction:
The resting membrane potential of the giant squid is around −50 millivolts (mV). The negative sign indicates that the inside of the cell is more negative than the outside. When the membrane potential becomes less negative, the condition is known as depolarization of the membrane.
The opening of the sodium channels results in passage of the sodium ions inside the cell. Thus, the membrane potential becomes less negative. The BTX (batrachotoxin) causes depolarization of the membrane.

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.

Find the dental formula and enter it in the following format:
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).
