Answer the following question given this paragraph: In summary, society is facing an antibiotic crisis. Some scientists believe that after years of being protected from bacterial infections by antibiotics, we may be returning to a time in which a simple bacterial infection could again devastate the human population. Researchers are working on developing new antibiotics, but few are in the drug development pipeline, and it takes many years to generate an effective and approved drug.

Q: Antibiotics can be used to fight what, in general? Choices: - fever - viruses - pathogens - bacteria A:
bacteria

Answer the following question given this paragraph: Single-displacement reactions are a subset of redox reactions. In this subset, what is oxidized and what is reduced? Give an example of a redox reaction that is not a single-displacement reaction. Q: Single-displacement reactions are a subset of what? Choices: - gravitational reactions - kinetic reactions - particle reactions - redox reactions A:
(Answer)
redox reactions
Ques: Answer the following question given this paragraph: The primary site of carbohydrate digestion is the small intestine. The secretion of amylase in the small intestine converts any remaining starch molecules, as well as the dextrins, to maltose. Maltose is then cleaved into two glucose molecules by maltase. Disaccharides such as sucrose and lactose are not digested until they reach the small intestine, where they are acted on by sucrase and lactase, respectively. The major. Q: The primary site of carbohydrate digestion is in the? Choices: - large intestine - mouth - stomach - small intestine A:
Ans: small intestine
(Q).
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? Choices: - transesterification - esterisation - decarboxylation - esterification A:
(A).
esterification
Ques:Answer the following question given this paragraph: Most of the visible light on Earth comes from the sun. The sun and other stars produce light because they are so hot. They glow with light due to their extremely high temperatures. This way of producing light is called incandescence . Incandescent light bulbs also produce light in this way. When electric current passes through a wire filament inside an incandescent bulb, the wire gets so hot that it glows. Do you see the glowing filament inside the incandescent light bulb in the Figure below ?. Q: The way in which the sun produces light is called what? Choices: - tumescence - rays - photosynthesis - incandescence A:

Ans:incandescence
Ques: Answer the following question given this paragraph: An electrolytic cell is the apparatus used for carrying out an electrolysis reaction. In an electrolytic cell, electric current is applied to provide a source of electrons for driving the reaction in a nonspontaneous direction. In a voltaic cell, the reaction goes in a direction that releases electrons spontaneously. In an electrolytic cell, the input of electrons from an external source forces the reaction to go in the opposite direction. Q: What is the apparatus used for carrying out an electrolysis reaction? Choices: - Golgi apparatus - catalyst - an aqueous cell - an electrolytic cell A:
Ans:
an electrolytic cell
