In order, which lists the scenarios that have the least number of reflective surfaces tot he most reflective surfaces?
i. high angle of the sun; hits a dark, rough surface
ii. low angle of the sun; hits a light, smooth surface
iii. low angle of the sun; hits a dark, smooth surface
iv. high angle of the sun; hits a light, rough surface
1. i > iii > iv > ii
2. iv > ii > iii > i
3. i > iv > iii > ii
4. iii > ii > iv > i

Asolution of an enzyme and a substrate was placed in a water bath and the temperature of the reaction was raised gradually. the graph shown was plotted at the end of the experiment. what can be concluded from the graph? a) temperature has no effect on the activity of the enzyme. b) the effect of temperature on the enzyme is unpredictable. c) the enzyme shows increased activity up to a certain temperature. d) the activity of the enzyme is inversely proportional to the temperature.
