Q: Answer the following question given this paragraph: isolating the individual components, preservationists are better able to determine the condition of an object and those books and documents most in need of immediate protection. The simplest class of organic compounds is the hydrocarbons, which consist entirely of carbon and hydrogen. Petroleum and natural gas are complex, naturally occurring mixtures of many different hydrocarbons that furnish raw materials for the chemical industry. The four major classes of hydrocarbons are the alkanes, which contain only carbonhydrogen and carboncarbon single bonds; the alkenes, which contain at least one carboncarbon double bond; the alkynes, which contain at least one carboncarbon triple bond; and the aromatic hydrocarbons, which usually contain rings of six carbon atoms that can be drawn with alternating single and double bonds. Alkanes are also called saturated hydrocarbons, whereas hydrocarbons that contain multiple bonds (alkenes, alkynes, and aromatics) are unsaturated. Q: The simplest class of organic compounds is the what? A:

OPTIONS:
- particles
- Phenols
- gas
- hydrocarbons

A: hydrocarbons

input: OPTIONS:
- reproductive system
- lymphatic system
- digestive system
- nervous system Now, answer this question: Answer the following question given this paragraph: CHAPTER SUMMARY 35.1 Neurons and Glial Cells The nervous system is made up of neurons and glia. Neurons are specialized cells that are capable of sending electrical as well as chemical signals. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues. There are four main types of neurons: unipolar, bipolar, multipolar, and pseudounipolar neurons. Glia are non-neuronal cells in the nervous system that support neuronal development and signaling. There are several types of glia that serve different functions. Q: What anatomical system is made up of neurons and glia? A:
A:
output: nervous system

Answer the following question given this paragraph: Figure below shows the role of the atmosphere in the water cycle. Water vapor rises from Earth's surface into the atmosphere. As it rises, it cools. The water vapor may then condense into water droplets and form clouds. If enough water droplets collect in clouds they may fall as rain. This how freshwater gets from the atmosphere back to Earth's surface. Q: What does water vapor in the atmosphere cool and condense into? A:

OPTIONS:
- puddles
- rain
- oceans
- clouds

Answer: clouds

Problem: OPTIONS:
- habit
- inclination
- trait
- innate
Q: Answer the following question given this paragraph: One of the few innate behaviors in human beings is the grasp reflex. It occurs only in babies. Q: The grasp reflex in humans is an example of what kind of behavior? A:
Answer: innate

Problem:OPTIONS:
- proteins
- fats
- vitamins
- carbohydrates

Answer the following question given this paragraph: Carbohydrates are the most common type of organic compound. A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are called monosaccharides. Carbohydrates contain only carbon, hydrogen, and oxygen. Q: What is the most common type of organic compound? A:
****
A: carbohydrates

Problem:OPTIONS:
- nervous system
- digestive system
- renal system
- urinary system

Answer the following question given this paragraph: Disorders of the urinary system include kidney stones, kidney failure, and urinary tract infections. Q: What system disorders include kidney stones, kidney failure, and urinary tract infections? A:
****
A:
urinary system
