Question

46 chromosomes, and ( n = 23 ) because human
the models show two cells from an organism that has two pairs of chromosomes in
of its somatic cells.
complete the table to indicate whether each phrase describes cell a or cell b.

	cell a	cell b
is haploid
contains ( n ) chromosomes
represents a somatic cell
is diploid
contains ( 2n ) chromosomes

Explanation:

• Gametes: Are reproductive cells (sperm and egg). They are haploid (contain \(n\) chromosomes). Cell B has fewer chromosomes, so it represents a gamete.
• Somatic cells: Are body cells. They are diploid (contain \(2n\) chromosomes). Cell A has more chromosomes, so it represents a somatic cell.
• Haploid (\(n\)): Gametes are haploid. Since Cell B is a gamete, it is haploid and contains \(n\) chromosomes.
• Diploid (\(2n\)): Somatic cells are diploid. Since Cell A is a somatic cell, it is diploid and contains \(2n\) chromosomes.
