My little brother’s science teacher gave him a mini project. The guiding question is “What brand of paper towels is best?” Basically, there are barely any rules whatsoever. You can do anything you want to justify your claim. So far, he thinks that he could measure absorbency or something. However, this isn’t set in stone What experiments can he conduct? What should his research question that is answered by the experiments be? What can he measure? For some context, the person who does the best work out of the grade gets a free A+ on an upcoming test. In conclusion, what can he do to conduct a successful experiment, sound smart, and possibly get that free A+?

Many birth-control pills release a constant amount of synthetic estradiols and progesterone for 21 days, followed by 7 days when no hormones are ingested. which of the following statements most accurately describes the effects of birth-control pills? -birth-control pills maintain constant levels of estrogens and/or progesterone so there is no surge in lh and ovulation does not occur.-birth-control pills inhibit the development of the uterine lining so implantation of a fertilized oocyte cannot occur.-birth-control pills maintain constant levels of estrogens and/or progesterones and mask the release of the oocyte from the follicle.-the 7 days with no hormones does not allow a thick enough uterine lining to form so a fertilized oocyte cannot implant.
