Is it possible for nerves to regenerate, and if it is possible,
where would you expect regeneration to occur, in the CNS or PNS,
and why or why not? What part of a neuron can grow back, if at
all?
Where would you expect to see the insertion and positioning
controls for (a) the objective aperture (b) the selected area
aperture (c) the condenser aperture.
1. What pH would you expect for pure, freshly distilled
water?
2. CO2 can dissolve into the water by the reaction
below. By analyzing these products, would you expect pure water
left out in the air to become acidic or basic?
CO2 (g) + H2O
(l) ⟶ H2CO3 (aq)
3. Using the pHet simulation above, identify two acidic
solutions and two basic solutions. Write the pH of the solutions
that you identified.
Select the 'coffee' option from the dropdown menu and...
2. Would you expect greater income inequality in country A,
where there is a large disparity in age, or in country B, where
there is a small disparity in age? Explain your answer.
Discuss the potential fates of transmembrane proteins and
explain where you would expect to find a particular domain of a
plasma membrane transmembrane protein based on where this domain
was found when the protein was still present at the ER
membrane
Recall that some (but not most) proteins are brought to the ER
lumen via posttranslational translocation. Discuss how this
mechanism differs from cotranslational translocation.
Q2: Which molecule would be expected to expect the highest
boiling point as a pure substance that are molecular isomers with
the same molecular formula, C5H12? 10 vs 40 0C.
- neopentane ( Hint: (CH3)4 C
)

population?
3. Describe a population where you would expect to find a high
frequency of adult lactose tolerance.
4. Why is adult lactose tolerance frequent in that
