Which of the following statements about the intensity of a nerve response is true?

Select one:
a. A small voltage shift and a large voltage shift will yield the same nerve impulse as long as the stimulus reaches the threshold level.
b. A stimulus resulting in a greater voltage shift will result in a stronger nerve impulse and increased sense of perception in the brain.
c. A stimulus reaching the threshold level may or may not propagate a nerve impulse.
d. All stimuli, regardless of the strength, will always generate a nerve impulse.

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
