Answer the following question given this paragraph: Chemicals that are applied to farm fields include fertilizers and pesticides. Excess chemicals can be picked up by rainwater. The chemicals can end up in streams, ponds, lakes, or the ocean. Dissolved fertilizer causes tremendous numbers of water plants and algae to grow. This can lead to dead zones where nothing can live in lakes or the coastal oceans. Q: Dissolved fertilizer can ultimately lead to the creation of what in lakes or coastal oceans, which means a place where nothing can live? A:

OPTIONS:
- extinction zone
- deceased zone
- hydrothermal vent
- dead zone

Answer: dead zone

Problem: OPTIONS:
- fungi
- enfluenza
- microbes
- pathogen
Q: Answer the following question given this paragraph: Q: What is the name for a parasite that causes disease? A:

Problem:OPTIONS:
- transesterification
- esterisation
- decarboxylation
- esterification

Answer the following question given this paragraph: An esterification is a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid. Esterification is a subcategory of condensation reactions because a water molecule is produced in the reaction. The reaction is catalyzed by a strong acid, usually sulfuric acid. When the carboxylic acid butanoic acid is heated with an excess of methanol and a few drops of sulfuric acid, the ester methyl butanoate is produced. Methyl butanoate has the scent of pineapples. The reaction is shown below with both molecular and structural formulas. Q: What do you call a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid? A:
****
A: esterification

Problem:OPTIONS:
- ending
- middle
- concurrent
- beginning

Answer the following question given this paragraph: Reactant concentrations are highest at the beginning of a reaction. The plot of [C] versus tis a curve with a slope that becomes steadily less positive. Q: Reactant concentrations are highest at which part of a reaction? A:
****
A:
beginning
