Dr. Williamson most likely to be studying <u>"hypothalamus".</u>
The hypothalamus is a little locale of the brain. It's situated at the base of the mind, close to the pituitary gland.
While it is very little, the hypothalamus assumes a pivotal part in numerous critical capacities, including discharging hormones, directing body temperature, keeping up day by day physiological cycles, controlling craving, overseeing of sexual conduct and controlling enthusiastic reactions.
I think that the key point here is the "easily reproducible" - because all of them can be scientific questions (even a! it could tell us about about the human psyche!)
but d. is the best answer for a reproducible experiment. B could also make a good experiment, but it would be too expensive to be easily reproducible. C is calling for a more complex analysis that is too complex for an experiment. And a would require more questionnaires than experiments
Answer:
A closed primary is a type of primary election in which a voter must affiliate formally with a political party in advance of the election date in order to participate in that party's primary. Other primary election types include: 1) open primaries, in which a voter either does not have to formally affiliate with a political party in order to vote in its primary or can declare his or her affiliation with a party at the polls on the day of the primary; 2) hybrid primaries, in which previously unaffiliated voters may participate in the partisan primary of their choice; and 3) top-two primaries, in which all candidates are listed on the same primary ballot and the top two vote-getters, regardless of their partisan affiliations, advance to the general election.
