In the lab, you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating form. if you released that mutant into a small pond shaded by trees, would the mutation spread, and why?
a) yes, because the xanthophylls prevent the production of reactive oxygen species.
b) no, because the xanthophylls prevent the production of reactive oxygen species.
c) no, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.
d) yes, because the heat released by the xanthophylls would warm up the cells and enhance photosynthesis.
e) no, because mutations never spread in nature

Four different thermometers were used to measure the temperature of a sample of pure boiling water. the measurements are recorded in the table below. thermometer temperature reading 1 temperature reading 2 temperature reading 3 w 100.1°c 99.9°c 96.9°c x 100.4°c 102.3°c 101.4°c y 90.0°c 95.2°c 98.6°c z 90.8°c 90.6°c 90.7°c the actual boiling point of pure water is 100.0°c. what can be concluded from the data about the reliability and validity of the thermometers?
