input: OPTIONS:
- consistent atoms
- hydrogen atoms
- liquid atoms
- carbon atoms Now, answer this question: Answer the following question given this paragraph: Figure 10.43 Diamond is extremely hard because of the strong bonding between carbon atoms in all directions. Graphite (in pencil lead) rubs off onto paper due to the weak attractions between the carbon layers. An image of a graphite surface shows the distance between the centers of adjacent carbon atoms. (credit left photo: modification of work by Steve Jurvetson; credit middle photo: modification of work by United States Geological Survey) You may be less familiar with a recently discovered form of carbon: graphene. Graphene was first isolated in 2004 by using tape to peel off thinner and thinner layers from graphite. It is essentially a single sheet (one atom thick) of graphite. Graphene, illustrated in Figure 10.44, is not only strong and lightweight, but it is also an excellent conductor of electricity and heat. These properties may prove very useful in a wide range of applications, such as vastly improved computer chips and circuits, better batteries and solar cells, and stronger and lighter structural materials. The 2010 Nobel Prize in Physics was awarded to Andre Geim and Konstantin Novoselov for their pioneering work with graphene. Q: Diamond is extremely hard because of the strong bonding between ______ in all directions? A:
A:
output: carbon atoms

Answer the following question given this paragraph: Proteins are nutrients made up of smaller molecules called amino acids . Recall that there are 20 different amino acids arranged like "beads on a string" to form proteins. These amino acid chains then fold up into a three-dimensional molecule, giving the protein a specific function. Proteins have several important roles in the body. For example, proteins make up antibodies, muscle fibers and enzymes that help control cell and body processes. You need to make sure you have enough protein in your diet to obtain the necessary amino acids to make your proteins. Q: How many amino acids are arranged like "beads on a string" to form proteins? A:

OPTIONS:
- 15
- 35
- 25
- 20

Answer: 20

Problem: OPTIONS:
- collective
- urban
- social
- municipal
Q: Answer the following question given this paragraph: "Municipal" refers to the community. Households and businesses in a community can pollute the water supply. Municipal pollution comes from sewage, storm drains, septic tanks, boats, and runoff from yards. For example:. Q: What type of pollution comes from sewage, storm drains, septic tanks, boats, and runoff from yards? A:
Answer: municipal

Problem:OPTIONS:
- Aids
- gonorrhea
- syphilis
- herpes

Answer the following question given this paragraph: This lip blister, or cold sore, is caused by a herpes virus. The virus is closely related to the virus that causes genital herpes. The genital herpes virus causes similar blisters on the genitals. If you've ever had a cold sore, you know how painful they can be. Genital herpes blisters are also painful. Q: What type of virus can cause painful sores on the mouth and genitals? A:
****
A: herpes

Answer the following question given this paragraph: The frequency of sound waves is measured in hertz (Hz), or the number of waves that pass a fixed point in a second. Human beings can normally hear sounds with a frequency between about 20 Hz and 20,000 Hz. Sounds with frequencies below 20 hertz are called infrasound . Infrasound is too low-pitched for humans to hear. Sounds with frequencies above 20,000 hertz are called ultrasound . Ultrasound is too high-pitched for humans to hear. Q: The frequency of sound waves is measured in what unit? A:
OPTIONS:
- watt
- rads
- decibel
- hertz
hertz

Answer the following question given this paragraph: Science is a process for developing knowledge. Change in knowledge about the natural world is expected because there is often room for new observations which may challenge current views. No matter how well one theory explains a set of observations, it is possible that a different theory may explain them just as well or better, or may also encompass a wider range of observations. Scientists are always testing and attempting to improve theories. Scientists know that even if there is no way to gain complete knowledge about something, an increasingly accurate understanding of nature will develop over time. Q: What is the process for developing knowledge called? A:
OPTIONS:
- evolution
- theory
- creationism
- science

Answer:
science
