Estrogen, a hormone, is released by the ovaries. Once released, it travels to cells where it has an influence on sexual development. In order for estrogen to achieve its purpose, it must: (A) - Travel through the cell membrane and bind to an intracellular receptor inside. (B) - Bind to a membrane receptor on the cell's surface. (C) - Estrogen does not need to cross the cell membrane to get to the nucleus. (D) - Travel using a transport protein to cross the cell membrane.

Targeted therapies are used in patients with a set gene expression pattern. A targeted therapy that prevents the activation of the estrogen receptor in breast cancer would be beneficial to which type of patient? a. patients who express the EGFR receptor in normal cells b. patients with a mutation that inactivates the estrogen receptor c. patients with lots of the estrogen receptor expressed in their tumor d. patients that have no estrogen receptor expressed in their tumor
When the estrogen-blocking drug tamoxifen was first introduced to treat breast cancer, there was concern that it would cause osteoporosis as a side effect. To test this concern, cancer subjects were randomly selected and given tamoxifen, and their bone density was measured before and after treatment. Which of the following is a true statement? (A) This study was an observational study. (B) This study was a sample survey of randomly selected cancer patients. (C) This study was an experiment in which the subjects were used as their own controls. (D) With the given procedure, there cannot be a placebo effect. (E) Causation cannot be concluded without knowing the survival rates.
