A cell that has two of every chromosome is called a(n) ____ cell.
A
haploid
B
diploid
C
zygote
D
homologous
Explanation: 

Detailed explanation-1: -Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism’s cells, with each parent contributing a chromosome to each pair. Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs.

Detailed explanation-2: -Cells that are diploid contain two copies of each chromosome and therefore two copies of each gene. The exception to this are males who have one X and one Y chromosome. One copy of each chromosome comes from each of the individual’s parents.

Detailed explanation-3: -Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).

Detailed explanation-4: -Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes).

Detailed explanation-5: -Haploid cells contain only one set of Chromosomes (n). Diploid, as the name indicates, contains two sets of chromosomes (2n). Haploid cells are formed by the process of meiosis.
