Answer:
The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.
The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.

Answer:
B - Python predation has caused a trophic cascade that changed the mosquitoes' niche.
Explanation:
The passage infers that the predation by the Burmese pythons has reduced the population of the animals in Southern Florida thus making the Culex cedecei mosquito to have a reduced number of options to feed from. This is stressed when the author notes that these mosquitoes are now feeding on cotton rats which harbor the Everglades virus that also have the potentials of being transmitted to humans.
Summarily, the passage is saying that the invasion by the Burmese python has changed the niche of most animals including the mosquitoes in the Southern Florida's wild.
