Answer:

The large eyed ducks had an undesirable trait, but the small eyed ducks have a desirable trait. Because the large eyed ducks had a trait that decreases their chances of survival, they wete killed. But small eyed ducks are lucky because they have a trait that increases their chance of survival. The small eyed ducks reproduce more offspring that have small eyes, but the large eyed ducks cannot because they didn't survive. This causes that the allele for large eyes in the gene pool to decrease.

Wich phase of the cell cycle is most affected by cytarabine
melisa1 [442]

Its mode of action is due to its rapid conversion into cytosine arabinoside triphosphate, which damages DNA when the cell cycle holds in the S phase (synthesis of DNA). Rapidly dividing cells, which require DNA replication for mitosis, are therefore most affected.
