Answer the following question given this paragraph: Compounds that contain mainly the elements carbon and hydrogen are called organic compounds . This is because they are found mainly in living organisms. Most organic compounds are held together by covalent bonds. An example of an organic compound is glucose (C 6 H 12 O 6 ), which is shown in Figure below . Glucose is a simple sugar that living cells use for energy. All other compounds are called inorganic compounds. Water is an example of an inorganic compound. Q: Compounds that contain mainly the elements carbon and hydrogen are called what kind of compounds? A:

OPTIONS:
- microscopic compounds
- reactive compounds
- natural compounds
- organic compounds

Answer: organic compounds

Problem: OPTIONS:
- kinetic mutation
- biochemical mutation
- muscular mutation
- chromosomal mutation
Q: Answer the following question given this paragraph: A mutation that changes all or a large part of a chromosome is called a chromosomal mutation. This type of mutation tends to be very serious. Sometimes chromosomes are missing or extra copies are present. An example is the mutation that causes Down syndrome. In this case, there is an extra copy of one of the chromosomes. Q: What is a mutation that changes all or much of a particular chromosome? A:
Answer: chromosomal mutation

Problem:OPTIONS:
- charger
- amplifier
- battery
- capacitor

Answer the following question given this paragraph: 19.5 Capacitors and Dielectrics A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.13. (Most of the time an insulator is used between the two plates to provide separationsee the discussion on dielectrics below. ) When battery terminals are connected to an initially uncharged capacitor, equal amounts of positive and negative charge, +Q and Q , are separated into its two plates. The capacitor remains neutral overall, but we refer to it as storing a charge. Q: What do we call a device used to store electric charge? A:
****
A: capacitor

Answer the following question given this paragraph: Because energy is a product, energy is given off by the reaction. Therefore, this reaction is exothermic. Because energy is a reactant, energy is absorbed by the reaction. Therefore, this reaction is endothermic. Q: In an endothermic reaction, what is absorbed by the reaction? A:
OPTIONS:
- food
- fuel
- atoms
- energy
energy

Answer the following question given this paragraph: 12.7 Molecular Transport Phenomena: Diffusion, Osmosis, and Related Processes 62. You can smell perfume very shortly after opening the bottle. To show that it is not reaching your nose by diffusion, calculate the average distance a perfume molecule moves in one second in air, given its diffusion constant D to be 1.0010 6 m 2 /s . What is the ratio of the average distances that oxygen will diffuse in a given time in air and water? Why is this distance less in water (equivalently, why is D less in water)? 64. Oxygen reaches the veinless cornea of the eye by diffusing through its tear layer, which is 0.500-mm thick. How long does it take the average oxygen molecule to do this? 65. (a) Find the average time required for an oxygen molecule to diffuse through a 0.200-mm-thick tear layer on the cornea. 3 (b) How much time is required to diffuse 0.500 cm of oxygen to the cornea if its surface area is 1.00 cm 2 ? 66. Suppose hydrogen and oxygen are diffusing through air. A small amount of each is released simultaneously. How much time passes before the hydrogen is 1.00 s ahead of the oxygen? Such differences in arrival times are used as an analytical tool in gas chromatography. Q: Oxygen reaches what veinless part of the eye by diffusing through its tear layer? A:
OPTIONS:
- retina
- pupil
- membranes
- cornea

Answer: cornea

input with options: Answer the following question given this paragraph: Most of the energy used by living things comes either directly or indirectly from the sun. That's because sunlight provides the energy for photosynthesis. This is the process in which plants and certain other organisms synthesize glucose (C 6 H 12 O 6 ). The process uses carbon dioxide and water and also produces oxygen. The overall chemical equation for photosynthesis is:. Q: Most of the energy used by living things comes either directly or indirectly from what? A:
OPTIONS:
- plants
- the moon
- the soil
- the sun
output:
the sun
