The follicular phase begins with an increase in follicle-stimulation hormone (FSH), which causes increases in luteinizing hormone (LH) and gonadotropin-releasing hormone (GnRH). Concurrent increases in estrogen levels cause increases in progesterone, stimulating proliferation of the endometrium.
Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air. The division of materials into the categories of conductors and insulators is a somewhat artificial division. It is more appropriate to think of materials as being placed somewhere along a continuum.
A: Lemons are generally the best fruits for conducting electricity. The high acid content in these and other citrus fruits, such as oranges and limes, makes them superior conductors. Since lemons have more acid than other citrus fruits, they are usually the best conductors.
