What evidence suggests that a cell spends the majority of its time in interphase? A. Only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. B. A large percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. C. A moderate percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. D. Mitosis is too intricate a process to last very long.

A. Only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.

Explanation:

The evidence that suggests that a cell spends the majority of its time in interphase is the fact that only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.

If such is not the case, a moderate to a large number of cells in tissue or cell culture should be seen in active mitosis.

Because of the longer nature of interphase when compared to mitosis, more cells are caught in the interphase stage of the cell cycle than the mitotic phase.

The correct option is A.

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.
