Answer the following question given this paragraph: until all atoms have octets. Because some atoms will lose electrons and some atoms will gain electrons, there is no overall change in the number of electrons, but individual atoms acquire a nonzero electric charge. Those that lose electrons become positively charged, and those that gain electrons become negatively charged. Charged atoms are called ions. Because opposite charges attract (while like charges repel), these oppositely charged ions attract each other, forming ionic bonds. The resulting compounds are called ionic compounds and are the primary subject of this chapter. The second way for an atom to obtain an octet of electrons is by sharing electrons with another atom. These shared electrons simultaneously occupy the outermost shell of more than one atom. The bond made by electron sharing is called a covalent bond. Covalent bonding and covalent compounds will be discussed in Chapter 4 "Covalent Bonding and Simple Molecular Compounds". Q: Because opposite charges attract, oppositely charged ions attract each other to form what? A:
OPTIONS:
- nuclear bonds
- particle bonds
- soluble bonds
- ionic bonds

Answer: ionic bonds

Question: Answer the following question given this paragraph: A desmosome is a cell junction specialized for cell-to-cell adhesion. They are found in simple and stratified squamous epithelium, and in muscle tissue where they bind muscle cells to one another. These junctions are composed of complexes of cell surface adhesion proteins and linking proteins. These proteins have both an intracellular and extracellular region. Inside the cell, they attach to intracellular filaments of the cytoskeleton. Outside the cell, they attach to other adhesion proteins. Q: Where are the desmosome found in a cell? A:
OPTIONS:
- epithelial
- neuron
- coating
- epithelium
Answer: epithelium

input with options: Answer the following question given this paragraph: The problem doesn't stop with plowing. Crops are usually planted in rows, with bare soil in between the rows. In places where crops grow only during part of the year, the land may be bare for a few months. Q: In places where crops grow only during part of the year, the land may be bare for a few? A:
OPTIONS:
- days
- weeks
- minutes
- months
output: months

Q: Answer the following question given this paragraph: Before catalytic converters were required, cars spewed a lot of pollutants into the air. On the left is a car without a catalytic converter. The car on the right has one. Q: What are the winds that occur in belts that encircle the planet? A:

OPTIONS:
- global rains
- new winds
- galactic winds
- global winds

A: global winds

input: OPTIONS:
- smoke
- rain
- hail
- fog Now, answer this question: Answer the following question given this paragraph: Rock bands often use special stage effects, like the fake fog in this picture. Real fog forms when water vapor in the air condenses into tiny droplets of water. The fake fog shown here formed when solid carbon dioxide changed directly to carbon dioxide gas. Q: What is formed when water vapor in the air condenses into tiny droplets? A:
A:
output: fog

Question: Answer the following question given this paragraph: Nucleic acids are one of four classes of biochemical compounds. (The other three classes are carbohydrates, proteins, and lipids. ) Nucleic acids include RNA (ribonucleic acid) as well as DNA (deoxyribonucleic acid). Both types of nucleic acids contain the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus. Q: Rna and dna are types of what biochemical compounds containing the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus? A:
OPTIONS:
- hormones
- nitrous acids
- amino acids
- nucleic acids
Answer:
nucleic acids
