Which phase of cell division is shown in this visual?

a) metaphase of mitosis.

b) telophase of mitosis.

c) metaphase 1 of meiosis.

d) prophase 1 of meiosis.

The right answer is A) Metaphase of mitosis.

During one of the phases of mitosis (the metaphase), the chromosomes (in the form of a cross) are positioned in the center of the cell thanks to the mitotic spindle (the white lines), so that in the anaphase there is a disjunction of the centromeres (the center of the chromosomes).

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.
