You decide to test peptides 1 and 2 using an in vivo model (in mice). for this experiment, you prepare tissue grafts loaded with a starting culture of wild-type s. aureus and surgically implant them into mice. in the control treatment, you don't add either peptide to the graft. you run six different experimental treatments in which you add each peptide alone to the graft, or you add both peptides to the graft. you also test a single dose of peptide versus three doses spread out over the experiment. after seven days, you remove the grafts and measure the amount of toxin present. your results are shown below.

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.

The leopard frog and the pickerel frog are two closely related species. in areas where their ranges overlap, the frogs will remain separate species if they
