Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
point b i think, because you have to see the amount of steepness in the slope.

No, the correct answer is Ecosystem
B
Secondary succession means the regrowth in an ecosystem that already existed, after a disaster such as floods, fire, and etcetera. This is as opposed to primary succession whereby a new ecosystem is developed where none existed initially, usually on a new substrate.
Explanation:
In the picture on the left looks like a picture of a forest decimated by fire. On the right is a picture of the grass growing on the forest floor. This probably due to the fact that the canopy of the forest was destroyed in the fire enabling sunlight to penetrate to the floe of the forest supporting vegetation growth. This secondary succession. The grass acts like pioneer species. Later, the forest floor will be colonized by perennial, and then woody plants and the ecosystem will be back to its normal state.
