One of the most important reasons for only using reliable water source is to reduce?

Answers

one of the most important reasons for only using reliable water source is to reduce : Infections

Without laboratory testing, it is impossible to actually known what type of contamination that a water source have.
For all we know, a water source could contaminated with chemicals or bacteria that could caused internal infections within our body

The right answer is The number of parasites, such as Cyclospora Cayetanensis.

The health risks associated with water are due to the use of polluted water, unfit for the intended use, for example:

- Consumption of water (beverage, ...), live products or products grown in aquatic environments (shellfish, ...);

- Swimming ;

- Use in a hospital environment (hot water, ultra pure water, ...).

Depending on the pollutants, the health risk is of an infectious nature (viruses, bacteria, parasites, fungi), chemical (mineral, organic), or physical (thermal, radioactive).

The risks involved are more or less long term. Some are known and proven for health, and others are suspected or even emerging.

Answers

Answer;

The enzyme structure begins to break downintermolecular bonds are broken

enzyme molecules gain kinetic energy.


Explanation;

Enzymes are proteins that play an important function in the body of catalyzing reactions in the body.

Enzymes work best at optimum temperature; low temperature lower than optimum temperatures deactivates them and higher temperature denatures them.

The shape of an enzyme depends on its temperature; when they get too warm they get loose, and at very low temperatures they get too tight. At optimum temperature or at the right temperature then they are just at the right shape and the chemical reactions they catalyze will be at optimal rate.
