Explanation / Answer

1) Receiving fewer calories than one’s minimum dietary requirements?

undernutrition
overnutrition
malnutrition
anemia

ANSWER is : undernutrition

EXPLANATION:

- malnutrition is the condition that results from eating a diet in which certain nutrients are lacking, in excess or imbalance of nutrients.

- undernutrition: not enough calories means there are deficiencies.

- overnutrition is condition of too many calories.

Bioethanol is an alcohol which made by fermentation, from carbohydrates that are produced in sugar or starch for example corn, sugarcane, or sweet sorghum


3) Which of the following is NOT a negative effect of monoculture?
reduces need for irrigation, fertilizers, and pesticides
narrows human diet
susceptibility to disease
reduces biodiversity

ANSWER is: reduces need for irrigation, fertilizers, and pesticides

EXPLANATION:

The negative effect of monocultures are decrease in biodiversity, increase in susceptibility to disease and pests, narrows human diet.


4) What is the main purpose of a seed bank?

A seed bank stores seeds to preserve genetic diversity.

5) Bedrock is a parent material for soil formation: True


Parent material from which soil develops comes from different sources because parent material is not static. Bedrock is not only a parent material for soil formation.


6) O Horizon : humus that is the surface litter, decomposing plant matter.

A horizon : topsoil.

E Horizon : zone of leaching.

B Horizon :This is the subsoil that is an accumulation of leached minerals like iron and aluminum oxides.

C Horizon : It is the weathered parent material


7) Desertification increases soil productivity : False

EXPLANATION :

Desertification is a process of land-degradation by which land becomes drier and productive land is transformed into wasteland.
