19) I think the cell is eukaryotic because of it's shape
20) Prophase (added an image with more information)
21) There are 12 chromatids and 6 chromosomes present (chromatids are 1 of the of two identical halves of a replicated chromosome)

Answer:
A. Advantageous alleles do not arise on demand.
Explanation:
According to theory of evolution, heritable traits in organisms can change across the generations leading to their evolution. There are many evolutionary forces like natural selection, mutation, genetic drift etc. However, it is incorrect to assume that the advantageous alleles will always be selected in evolution. Accumulation of random mutations, genetic drift or bottle neck effect are independent of this factor. Also, organisms with different degree of beneficial traits can coexist in same time frame. Just because humans evolved in a particular direction does not mean that other organisms will also do so.
