25) what does the central nervous system use to determine the strength of a stimulus? a) origin of the stimulus b) frequency of action potential  c) amplitude of action potentials d) type of stimulus receptor

33) which of the following brain areas helps with interpretation of taste? a) gustatory cortex b) auditory association area c) visceral sensory area d) visual association area

You are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this? a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it. b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations. c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations. d) all of the above.     ( well explain  the correct  answer  and type answer).
