What is the benefit to using tissue cultures with cancer patients? doctors can study how quickly cancer spreads in the culture so they know what medicine to use. medications can be tested on the cancer culture before being injected into the patient. the cancer culture can be studied to determine if oral medicine is the best treatment for the patient.

Correct B). Medications can be tested on the cancer culture before being injected into the patient.

Medications have the dangerous side effects on the body and it may or may not be effective in killing or inhibiting the growth of a cancerous cell. That is why now a days tissue culture technique is used to test the potential drug before administrating it to the patient.

Growing cancer cell in the laboratory is a good way to learn about cancer and to determine the effective medicine against a particular type of cancer.  

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.
