Q: Answer the following question given this paragraph: Cleavage is the tendency of a mineral to break along certain planes. When a mineral breaks along a plane it makes a smooth surface. Minerals with different crystal structures will break or cleave in different ways, as in Figure below . Halite tends to form cubes with smooth surfaces. Mica tends to form sheets. Fluorite can form octahedrons. Q: What term means the tendency of a mineral to break along certain planes? A:

OPTIONS:
- cavity
- fault
- fracture
- cleavage

A: cleavage

input: OPTIONS:
- have
- drink
- eat
- lack Now, answer this question: Answer the following question given this paragraph: Plant cells have structures that animal cells lack. What important process takes place in plant cells but not in animal cells that might explain their differences?. Q: Plant cells have structures that animal cells? A:
A:
output: lack

Answer the following question given this paragraph: An example of a disaccharide is sucrose (table sugar), which consists of the monosaccharides glucose and fructose ( Figure below ). Other common disaccharides include lactose ("milk sugar") and maltose. Monosaccharides and disaccharides are also called simple sugars . They provide the major source of energy to living cells. Q: What are monosaccharides and disaccharides also called? A:

OPTIONS:
- simple chemicals
- basic sugars
- complex sugars
- simple sugars

Answer: simple sugars

Problem: OPTIONS:
- metallic bond
- ionic bond
- hydrogen bond
- covalent bond
Q: Answer the following question given this paragraph: Ionic bonding typically occurs when it is easy for one atom to lose one or more electrons and another atom to gain one or more electrons. However, some atoms won't give up or gain electrons easily. Yet they still participate in compound formation. How? There is another mechanism for obtaining a complete valence shell: sharing electrons. When electrons are shared between two atoms, they make a bond called a covalent bond. Let us illustrate a covalent bond by using H atoms, with the understanding that H atoms need only two electrons to fill the 1s subshell. Each H atom starts with a single electron in its valence shell:. Q: When electrons are shared between two atoms, they make a bond called a what? A:
Answer: covalent bond

Problem:OPTIONS:
- permeation
- absorption
- convection
- diffusion

Answer the following question given this paragraph: Small molecules can pass through the plasma membrane through a process called diffusion. Diffusion is the movement of molecules from an area where there is a higher concentration (larger amount) of the substance to an area where there is a lower concentration (lower amount) of the substance ( Figure below ). The amount of a substance in relation to the total volume is the concentration . During diffusion, molecules are said to flow down their concentration gradient , flowing from an area of high concentration to an area of low concentration. Molecules flowing down a concentration gradient is a natural process and does not require energy. Q: What is the process of small molecules passing through the plasma membrane called? A:
****
A: diffusion

Problem:OPTIONS:
- flammable
- geothermal
- reversible
- exothermic

Answer the following question given this paragraph: All combustion reactions are exothermic reactions. During a combustion reaction, a substance burns as it combines with oxygen. When substances burn, they usually give off energy as heat and light. Look at the big bonfire in the Figure below . The combustion of wood is an exothermic reaction that releases a lot of energy as heat and light. You can see the light energy the fire is giving off. If you were standing near the fire, you would also feel its heat. Q: All combustion reactions are what type of reactions? A:
****
A:
exothermic
