Question

the cells labeled a: *
zygote
gametes
fertilization
meiosis
mitosis
the cells made in c (labeled b) are: *
haploid
diploid
triploid

Explanation:

Step1: Identify cells labeled a

In the human life cycle, the cells produced by meiosis (from diploid adults) are gametes (sperm/egg), which match the labeled cells marked as "sperm cell" in the diagram.

Step2: Identify ploidy of cells from c

Process c is meiosis, which reduces the chromosome number from diploid ($2n=46$) to haploid ($n=23$). The cells made (labeled b, gametes) are haploid.

Answer:

1. B. gametes
2. A. haploid
