You look online and see the cure for Malaria is a drug called Quinine. In order to prepare the solution properly, you need to know your roommate’s weight. You figure out that your roommate weighs 65,000 g, but the medicine dosage is based on the number of kilograms the patient weighs. How many kilograms are in 65,000 g? (Numerical answer only))

Read the lab description and answer questions 1-7 Jack was tasked with determining which brand of pen is most likely to attract a termite. He selected 5 brands of black ink pen, Bic, Precision V5, Sharpie, Papermate, Pilot, plus a pencil. Jack knows from previous experience that the termites are attracted to ink from a black Bic pen and are not attracted to lead from a pencil. To complete the experiment Jack drew a 7 cm diameter circle with each pen and placed a termite 0.25 cm from each circle. He then gave the termite 60 seconds to find the circle and travel around the circle. Jack defined positive results as a termite finding the circle within 60 seconds and then following the circle at least half way around. A negative result would be a termite that was unable to find the circle within 60 seconds or a termite that found the circle but followed it for less than half the circle. Jack tested ten termites on each brand of pen for a total of sixty termites. The results of Jack’s experiment are found in the table below.

Read the lab description and answer questions 1-7 Jill was tasked with determining which brand of pen is most likely to attract a termite. She selected 5 brands of black ink pen, Bic, Precision V5, Sharpie, Papermate, Pilot, plus a pencil. Jill knows from previous experience that the termites are attracted to ink from a black Bic pen and are not attracted to lead from a pencil. To complete the experiment Jill drew a 5 cm diameter circle with each pen and placed a termite 0.5 cm from each circle. She then gave the termite 30 seconds to find the circle and travel around the circle. Jill defined positive results as a termite finding the circle within 30 seconds and then following the circle at least half way around. A negative result would be a termite that was unable to find the circle within 30 seconds or a termite that found the circle but followed it for less than half the circle. Jill tested five termites on each brand of pen for a total of thirty termites. The results of Jill’s experiment are found in the table below.
