In the mare, list the three physical barriers that prevent contamination of the uterus. [a] [b] [c]

Consistent State part-4 Given  what is the expected state of ? (Your answer for the expected state of must be a three-character string where each character can only be 0, 1, E, L, or H.)

Trace the pathway of a single oxygenated erythrocyte as it leaves the pulmonary capillaries to travel into systemic circulation.

14. (WCSU26, 5 points)  Draw the structure shown below and add curved arrows to show the movement of electrons to give another resonance contributor. Draw this second resonance contributor. Be sure to include lone pairs and formal charges on your structure as needed.   In the box below, enter the number of C-N bonds in your resonance structure.

(WCSU26) Consider the following bonds: C-C C-O Si-O a.  The longest bond is [blank1]. b. Rank the bonds in order of increasing polarity. least polar   [blank2]

(WCSU26) Refer to the structure of glutathione below to answer the following about angles a and b and atoms c and d. a. The bond angle about angle a is: [blank1] degrees b.  The bond angle about angle b is: [blank2] degrees c.  The electron domain geometry of atom c is: [blank4] d.  The molecular geometry of atom c is: [blank5] e.  The hybridization of atom d is: [blank3]

15. (WCSU26, 8 points) Draw the complete Lewis structures (including lone pairs and formal charges) for the following molecules/ions: a.  ClO2- b.  CH4O   Periodic Table   In the box below, enter the total number of lone pairs in the two structures (a+b).

(WCSU26) Rank the molecules (a, b, and c) in order of increasing carbon-oxygen bond strength.    weakest   [blank1]

(WCSU26) We often use theory (valence bond, hybridization, resonance, etc.) to explain experimental data. When resonance (delocalized pi bonding) is present in a structure, what you see is not always what you get.  In the structure shown, the bond angles about nitrogen are 120 degrees.     Based on this information, give the following information: a. Molecular geometry about the nitrogen atom: [blank1] b. Hybridization of the nitrogen atom: [blank2] c. Name type of orbital holds the lone pair: [blank3]
