1,2 Why was it important that researchers use large sample sizes?a) It controls for all variables except for one.b) It holds the experimental conditions constant.c) It allows the researchers to create a null hypothesis.d) It reduces the amount of distortion or "noise" in the data caused by unusualindividuals or circumstances. The ability to sweat or pant is considered an adaptation. Why?a) It is an important signal to others that an individual is too hot.b) It cools a body off, due to water's high heat of vaporization.c) It allows a body to release excess water.d) It allows a body to absorb heat, due to water's high specific heat.

Rules of Significant Figures and Dimensional Analysis For centuries, the people of Paradis Island have been isolated from the rest of the world. The SI units are unknown to them. Expeditions sent to the island revealed that they created their own system of units, and some of their fındings are summarized in Tables 1 and 2. To help the Paradisians advance technologically, people from the outside are planning to construct a power plant on the island. The plant produces an average of 875.9 gigawatts (GW) of power. A. Calculate the average power rating of the plant in Arlert (R). (1 W = 1 kg-m²/s³) B. Calculate the energy produced by the plant in 5.400 x 104 s of operation. Express the result in Yeager (Y). (1 J = 1 W-s = 1 kg-m2/s²) (Note: Power = energy/time) C. How many households can be powered by the plant after 5.400 x 104 s of operation if each house consumes 1.50 x 1011 Y of energy? Table 1.
