Considering the following;

I. Heat is not readily available to all living cells.

II. Heat at excessive amounts denatures proteins.

III. Heat does not provide the activation energy for their reactions.

IV. When a critical temperature is reached, proteins no longer function

Answer;

I and IV

Explanation;

Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.

Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.

Why is myxoma no longer effective in controlling rabbit population?
Margaret [11]

The development of resistance to the disease has taken different courses. In Australia, the virus initially killed rabbits very quickly – about 4 days after infection. This gave little time for the infection to spread. However, a less virulent form of the virus then became prevalent there, which spread more effectively by being less lethal. In Europe, many rabbits are genetically resistant to the original virus that was spread. The survival rate of diseased rabbits has now increased to 35%, while in the 1950s it was near zero.[15]
