- Participating in atypical sexual behaviors is reported to occur more in males. Why do you think that is the case? Explain if you believe it is nature (i.e., genetics), nurture (i.e., environmental), or both.A study divides healthy females into two groups (A and B). Both groupsare composed of those who have been sexually active for at least 2 yearsand are not pregnant at the beginning of the experiment. The subjectsweigh about the same amount, and none smoke cigarettes, althoughsome drink alcohol occasionally. Group A individuals receive a placeboin the form of a sugar pill each morning of their menstrual cycles. GroupB individuals receive a pill containing estrogen and progesterone eachmorning of their menstrual cycles. Then plasma LH levels are measuredbefore, during, and after ovulation. The results are as follows:Group 4 Days BeforeOvulationDay ofOvulation4 Days AfterOvulationA 18 mg/100 mL 300 mg/100 mL 17 mg/100 mLB 21 mg/100 mL 157 mg/100 mL 15 mg/100 mLThe number of pregnancies in group A is 37/100 females/year. Thenumber of pregnancies in group B is 1.5/100 females/year. Whatconclusion can you reach on the basis of these data? Explain themechanism involved.What is the probability that these parents (XMLXML Have a superhero kid if the kid is male. Have a superhero kid if the kid is female.

What stimuli trigger the reflex? What two physiological mechanisms (other than the brain) are responsible for the physical changes that appear during the sexual response? [Hint: One begins with “va” and the other with “my.”] Give examples of the effects of both these two physiological mechanisms.
