The persons who would use the spray should not intake food or drink or even smoke during the process of spraying. They should also wash their hands after using the spray. This is a standard procedure in using chemicals to prevent intoxication.

As the owner of the company, I should be able to make sure that the chemical "Bunny-Hop-way" will not affect the growth and development of the plants. Aside from that, there should be a study if the chemical will not be harmful to the consumer who will eat the fruits and vegetables sprayed with the chemical.

Zebra muscles and gobies are introduced into the United States from the Caspian Sea. The ballast tanks of cargo ships release the water from the Caspian sea to the Great Lakes. Therefore, these species were transported into another habitat. They can cause biological pollution to the lake. The fish and birds may become victims of botulism, or food poisoning, caused by the foreign mussels and gobies.

Since the gobies are introduced, they became predators of the zebra mussels which absorbs PCBs from the lake water. Then the gobies are eaten by sport fish, which are consumed by humans. Therefore, the PCBs absorbed by the mussels are transferred to the gobies, and then to the sport fish.

Correct Answer: Option 2 heat household water with solar radiation

A non-renewable resource is a natural resource that cannot be produced, re-grown, regenerated, or reused on a scale which can sustain its consumption rate. These resources often exist in a fixed amount, or are consumed much faster than nature can recreate them. Fossil fuel (such as coal, petroleum and natural gas) is an example. Increase of industrialization would mean increase use of fossil fuel. Solar radiation, tides, winds and hydroelectricity are perpetual resources that are in no danger of long-term availability. Therefore, it is better to use solar radiation to produce heat than the other options.
