Answer:
HEALTH SECTOR(microorganisms have led to the most devastating diseases of man such as HIV VIRUS, HEPATITIS VIRUS, SALMONELLA TYPHI AND PARATYPHI SPPS)
INDUSTRY(microorganisms have led to masses losses due to contamination of foods like the GROWTH OF MOLDS)
ENVIRONMENT most contamination of the environment are caused by microorganisms.

4. Which of the following methods of soil conservation uses the roots of plants as anchors in the soil?
<span>Planting trees on sloped surfaces.
In this way, soil erosion is minimized as well as the amount of water run off.
5. </span><span>Which of the following soil components results from the breakdown of parent material?
</span><span>Minerals</span>
The answer would be 25%
Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.
Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%
