Tobin performed an experiment in which he mixed varying amounts of enzyme with an excess amount of substrate. he measured the rate of each reaction and recorded his data in the table below.
enzyme concentration
(millimoles) reaction rate
(micromoles/minute)
0 0
100 0.05
200 0.10
300 0.15
400 0.20
500 0.25
what can tobin conclude about the relationship between the enzyme concentration and the reaction rate in the presence of excess substrate?

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
