Question

using the same independent and dependent variables as in the first experiment, researchers could extend which of the following hypotheses? select the two answers that are correct. low intensity, long duration exposure to radiation has a greater influence on the incidence of cancer intensity, short duration exposure. cell phone radiation increases the life expectancy of rats. the incidence of cancer increases with increased levels of cell phone radiation. female rats are less likely to develop cancer than male rats. a low - fat diet decreases the incidence of cancer in rats.

Explanation:

The first option compares different types of radiation - exposure patterns on cancer incidence. The third option relates cell - phone radiation levels to cancer incidence. Both involve extending research with radiation as an independent variable and cancer - related outcomes as dependent variables. The second option relates radiation to life - expectancy which may not be in line with the initial cancer - focused research. The fourth option compares genders in cancer likelihood without relation to radiation. The fifth option involves diet instead of radiation.

Answer:

Low intensity, long duration exposure to radiation has a greater influence on the incidence of cancer than high intensity, short duration exposure.
The incidence of cancer increases with increased levels of cell phone radiation.
