Martin is studying sucrase activity. he added sucrose solution + sucrase solution + buffer of ph 5.6 in two tubes. he incubated them at 350c and 1000c respectively. when he performed a confirmatory test, only the first test tube showed enzyme activity. how would you justify the inactivity of the enzyme in the second test tube?

the enzymes in the second test tube must have denatured at ph 5.6, since most enzymes work at neutral ph.

the enzymes in the second test tube must have denatured at 1000c, since most enzymes degrade at such high temperatures.

enzymes must have remained dormant at 1000c, since most of the enzymes remain inactive at such higher temperatures.

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.
