Summary Introduction
Introduction:
A contraceptive is a drug or method or device that helps prevent pregnancy. It interferes with the normal method of ovulation, fertilization, and implantation to prevent pregnancy. It is also termed as birth control. Methods of contraceptives can be either temporary or permanent.
- Temporary Method: It includes the barrier method, which prevents sperm from reaching an egg. Temporary methods are condoms, vaginal diaphragms, birth control pills, intrauterine devices (IUDs), etc.
- Permanent Method: It includes a surgical process that permanently prevents the transport of sperm through the reproductive tract. Permanent methods are tubal ligation (in women) and vasectomy (in man).

A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2). Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin.
