Answer:
The correct answer is - Protein molecule.
Explanation:

Proteins are present as channels and in the form of membrane proteins in between the lipid bilayer. Protein is the molecule that denatured or destroyed at high temperatures such as 70 degrees.

The cane toad was a failure as a biological control method in Australia because:
-The greyback beetle it was supposed to be eating fed at the top of the sugarcane stalks (which were 6-8 meters in height). Cane toads cannot fly or climb and therefore couldnt feed on the beetles.
-The beetles were out during the daytime, and cane toads feed at night.
-The two species are not seasonally compatible (aren't in the same place at the same time of year).
-The toads needed moist conditions to survive, and so moved away from where they were supposed to be.
-The cane toad eats many native species and often out-competes native species for food and breeding sites, leading to the decline of natives.
-Breeding habits made the cane toads a very invasive species.
