Read the passage below and answer the questions that follows
Leukemia and Bone Marrow Transplant
Leukemia is a type of cancer which affects blood cells This disease
(as well as many other is caused by abnormal stem cells in the bone
marrow producing defective or immature blood cells. These abnormal
slem cells are usually treated by chemotherapy. Unfortunately, the large
doses of diemotherapy required also destroy healthy bone manow A
bone marrow transplant is necessary to replace the diseased and
damaged bone marrow

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

the denominator has a very specific role.
