The answers would be 24 and fertilises.
Pollen is the male gamete of lily, which is a haploid cell, with only half the chromosomes of the normal diploid ones. Therefore, if the haploid gamete has 12 chromosomes, so the diploid would be 12+12 which makes 24.
The egg is also a gamete of lily, but it's a female gamete. It is also a haploid cell, with only 12 chromosomes which is given in the question. So, when the sperm fuses and fertilises the egg, the zygote would have 24 chromosomes which is formed by 2 haploid gametes.
Beyond durability, cockroaches are built to play defense. They have an exoskeleton to protect their soft bodies, and will hide whenever they're in the process of molting their exoskeleton. The exoskeleton is not only rigid but flexible to allow the roach to crawl into tiny crevices. Their legs are built for running
