PATHOLOGY

Detailed explanation-1: -Option “B” is correct i.e. the number of genes in each chromosome. The number of genes in each chromosome determines sex. Human and chimpanzee chromosomes are very comparable. The main difference is that humans have one fewer pair of chromosomes than do other great chimpanzees.

Detailed explanation-2: -Humans have 46 chromosomes, whereas chimpanzee, gorilla, and orangutan have 48. This major karyotypic difference was caused by the fusion of two ancestral chromosomes to form human chromosome 2 and subsequent inactivation of one of the two original centromeres (Yunis and Prakash 1982).

Detailed explanation-3: -The sex cells of the chimpanzee are haploid (n) that contains only one homologous chromosome from each pair (egg and sperm). Hence, the number of sex chromosomes in the chimpanzee body cell is 1 pair or 2 chromosomes.

Detailed explanation-4: -Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born. They are called sex chromosomes: Females have 2 X chromosomes.

Detailed explanation-5: -Fungi. Of the major groups of saprotrophs, fungi are among the most efficient at decomposing complex organic molecules and recycling those nutrients back into the ecosystem. Fungi are some of the most-significant decomposers of plant matter, which makes up the vast majority of detritus in terrestrial environments.
