what's the answer? Question 1 1 pts USE THIS INFORMATION FOR ALL QUESTIONS: Many forms of cancer are influenced by hormones and growth factors. Some breast cancers are "HR-positive" or "HR-negative" and "HER2-positive" or "HER2-negative," meaning that the tumor cells have or lack hormone receptors (HR) for estrogen and/or progesterone, and they have or lack receptors (called HER2) for human epidermal growth factor 2 (hEGF-2). Where are estrogen receptors usually found? only on the outside of the plasma membrane. in...
