Answer: Denaturing
Explanation: Enzymes are made of amino acids that are linked by bonds, amongst those bonds are hydrogen bonds that are very weak. High temperatures and low pH(acidity) breaks those bonds changing the molecular conformation of the enzymes. That way they denature and loss the ability to perform their functions. High temperatures and acidity alter the structure of their active site preventing the substrate from binding to them. While high temperatures denatures enzymes, low temperature renders them inactive.

D. "Even a moderate dose of THC can produce perceptual distortions and coma"
Answer:
The correct answer is the first statement.
Explanation:
A fundamental stimulus-response coupling mechanism that helps various species to react and sense different modifications taking place in various distinct environmental circumstances is known as a two-component regulatory system. Though this system is found in almost all the domains of life, however, it is generally witnessed in species like bacteria, mainly in the Gram-negative and cyanobacteria.
In case, if the response regulator turns completely phosphorylated because of the absence of phosphatase activity, the cell would become insensitive towards the environmental stimulus. This generally happens as the cell will lose its tendency to sustain the response cycle because of the imbalance in the dephosphorylation and phosphorylation system that helps in sustaining the response of the cell towards a specific environmental stimulus.
Glycerides of higher fatty acids are oils are fats. Oils are liquids while fats are solids at room temperature or at 25 degree Celcius. Oils have some unsaturated acids forming triglycerides while fats are glycerides of mainly saturated higher fatty acids. Hope this helps.
