The variable affecting the enzyme action is temperature.
<h3><u>Explanation:</u></h3>
Catalase is the enzyme which acts upon the "substrate hydrogen peroxide", breaking down them into water and oxygen gas. Each and every enzyme is a protein, which has a tertiary structure which is essential for the enzyme action. The tertiary structure of the enzyme provides the site of enzymatic action where the substrate do gets attached for the enzymatic action to take place.
Temperature, or heat, changes the protein structures irreversibly after a certain range. So if the beef liver is boiled, then the enzyme structure gets permanently changed, which is why the catalase cannot breakdown the peroxides, after boiling.
The venom of a poison dart frog has the special ability of being quiet permeable through the skin. A dart frog's poison can travel up the nerves, into the brain leading from tingling to pain, to paralysis, to coma, and then death. Its agonising.

Explanation:
The goal of timing nitrogen (N) applications to corn is to supply adequate N when the crop needs it, without supplying excess that can potentially be lost. Because N reactions in the soil are closely linked to both temperature and moisture conditions, this goal is often hard to achieve.
Answer: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct
