Which is an example of chronic physiological toxicity? a. amotivational syndrome b. high blood pressure from smoking c. respiratory arrest from an alcohol overdose d. paranoia from methamphetamine use

Option B

Explanation:

Chronic physiological toxicity can be defined as the condition in which the toxicity is developed inside the body due to being in exposure to the toxicant or stressor.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
