Smaller mammals use proportionately more energy than larger mammals; that is, it takes more energy per gram to power a mouse than a human. a typical mouse has a mass of 20 {\rm g} and, at rest, needs to consume 3.0 cal each day for basic body processes.1. if a 68 {\rm kg} human used the same energy per {\rm kg} of body mass as a mouse, how much energy would be needed each day? 2. what resting power does this correspond to? 3. how much greater is this than the resting power noted in the chapter? p = ?

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth
