Answer:

The correct answer is - one factor.

Explanation:

A well-designed experiment is an experiment that permits researchers to remove or discard the extra variables as a description or explanation for the independent and dependent variable relation,

In a well-designed experiment, scientists test a single variable or factor at a time and should be clearly identified easily. There should be one controlled system in a well-designed experiment.

Thus, the correct answer is - one.

Solar, wind, and hydroelectric energy<br> are examples of<br> resources.
strojnjashka [21]

Answer:

Renewable Energy Resources.

Explanation:

Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.

Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.

Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
