31. the asnwer in back says it's e, all are hardy weinberg conditions. a) is NOT. no isolation = gene flow. The population must be isolated from other populations to meet the hardy equilibrium

176. the correct answer should be c. just look it up on wiki or campbell

gen chem

31. the units are mixed up. 1 L atm = 101 J = .1 kj
24L*4atm=96 L atm = 9600 J = 9.6KJ


163. ClF5. all choices are Clf4 though

OChem

119. neither methylamine nor ether reacts with grignard reagents. if there were only one choice we could pick, methyamine should be the one because it's more basic

I was thinking about it....let me know what you think

5 assumptions:
1) Large population
2) No migration (in or out)
3) No mutations
4) Random mating
5) No natural selection

The questionable answer choice is No isolation....can you tie in isolation with random mating??

If a population is isolated that would increase the chance for interbreeding which goes against assumption #4. Therefore No isolation should occur under the hardy-weinburg.

31. In the case with population questions isolation refers to either a physical barrier, a charge in physical reproduction structure, or even a change in mating patterns can cause a segment of the population to be isolated from the original population. Therefore a population must no be in a state of isolation to be considered in equilibrium. What populations must we be isolated from? I believe you are referring to either the isolation from other species which is already anate or isolation from members of others of the same species which is simply a matter of how you define the population.

136. Your right

Orgo: Methlyamine doesn't react with grignard? This is essentially a solvent pairing question. What solvent is used with a grignard reagent? Aprotic solvent, lacking acidic hydrogens, such as diethylether. Methylamine is a primary amine which has protic hydrogens (N-H). .

Is this in regards to the bio section, and is this a mistake, if so, what's the deal with this? Thanks again
