Martin is studying sucrase activity. he added sucrose solution + sucrase solution + buffer of ph 5.6 in two tubes. he incubated them at 35°c and 100°c 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?
a. the enzymes in the second test tube must have denatured at ph 5.6 since most enzymes work at neutral ph
b. the enzymes in the second test tube must have denatured at 1000c, since most enzymes degrade at such high temperatures.
c. enzymes must have remained dormant at 1000c, since most of the enzymes remain inactive at such higher temperatures.

List two new traits (structural or behavioral) that each new species of rat might demonstrate as it adapts to the conditions on two of the four islands. choose only two islands that are described in the lesson. record the island latter and the major habitat feature of the island. then list two new traits each rat subspecies might demonstrate in order to survive the habitat on that island. note: new traits should be unique to that island and be in response to that island’s habitat feature. i cannot remember islands that were names in the lesson so only answer if you have done the lesson (5.13 life science 7b) choose 2 of the islands and describe a structural and a behavioral trait for a rat on each island so 4 total answers, 2 different structurals and 2 different behaviorals, one for each rat for each island
