<span>Electron microscopes therefore allow for the visualization of structures that would normally be not visible by optical microscopy. Light microscopes are not able to see things in a larger magnification compared to electron microscopes. Also you're able to see in 3d in electron microscopes and you can't see in 3dimentsional in light microscopes.

Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
- Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.
- This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.
- The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.
As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

Instructions for each specific function
<span>Reproductive isolation prevents variations from spreading throughout the entire population. Since genetic variations basically occur randomly, the chances that the same variations will occur in both reproductively separated subpopulations are vanishingly slim. Thus, genetic divergence between both subpopulations will occur, and this may eventually lead to speciation. Isolation stops populations of the same species from interbreeding. This results in separate breeding among populations and genetic differences become more pronounced with each generation.</span>
