Compare and contrast prezygotic and postzygotic isolating mechanisms in evolution. In your explanation, clearly define the fundamental difference between these two categories based on when they act during reproduction, provide and describe two specific types of mechanisms for each category, and explain how these barriers contribute to the process of speciation.

A section of a DNA template strand has the following base sequence: A T C G T A C G C. During DNA replication, a mutation has caused an error resulting in a new strand:                                                 A T C T A C G C. a. Create the complementary base sequence for the opposite strand of the mutated DNA double helix. (1 mark) b. Identify the specific point mutation that has occurred

Compare and contrast what happens to a plant cell when it is placed in a hypertonic solution versus a hypotonic solution. In your explanation, discuss the relative solute concentrations of each environment, the net direction of water movement across the cell membrane, and the resulting physical state or appearance of the cell.
