1. what is prior to the immunity of the body for killing the viruses and cancer cell?

a. natural killer cell
b. B-cells
c. T-cells

2. How many different genotype can this have? My ans. is 2.

AaBBcc


3. when Delta G is positive, is the rxn
a.spont.
b.nonspont.
c. exergonic
d. endergonic
e. will do work


4. which of the following is plainer:

a. CO3
b. ICl3
c. KMnO4

5. IR absorption of 3080(sharp) and 1700. what is the compound?

a. ketone
b. aldehyde
c. alkane
d. alkene

3080 is for alkene =CH and 1700 is for having a carbonyl. so i would have to go with aldehyde.

can you explain why ICl3 is a plainer?
Hmm you know now that I think of it it might be CO3, because ICL3 is planar when it is a dimer (2 I atoms and 6 CL) But from this photo we see that CO3 forms a complex where the 2 O atoms bond to each other, making it planar? I'm not sure sorry if i misled anyone
