Q: Answer the following question given this paragraph: Group 16 of the periodic table is also called the oxygen group. The first three elementsoxygen (O), sulfur (S), and selenium (Se)are nonmetals. They are followed by tellurium (Te) ( Figure below ), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive. Oxygen is a gas at room temperature, and the other elements in the group are solids. Q: What is group 16 of the periodic table referred to? A:

OPTIONS:
- sulfur group
- dioxide group
- acid group
- oxygen group

A: oxygen group

input: OPTIONS:
- nucleus
- cell wall
- golgi apparatus
- cell membrane Now, answer this question: Answer the following question given this paragraph: The cell membrane also decides what may enter or leave a cell. The membrane is said to be semipermeable or selectively permeable, allowing only certain ions and organic molecules to cross the membrane. The plasma membrane contain many proteins, as well as other lipids called sterols. The proteins have various functions, such as channels (channel proteins) that allow certain molecules into the cell, and receptors (receptor proteins) that bind to signal molecules. In Figure above , the smaller (green) molecules shown between the phospholipids are cholesterol molecules. Cholesterol helps keep the plasma membrane firm and stable over a wide range of temperatures. At least ten different types of lipids are commonly found in plasma membranes. Each type of cell or organelle will have a different percentage of each lipid, protein and carbohydrate. Q: What decides what may enter or leave a cell? A:
A:
output: cell membrane

Answer the following question given this paragraph: An example of a chemical reaction is the burning of methane. In this chemical reaction, the reactants are methane (CH 4 ) and oxygen (O 2 ), and the products are carbon dioxide (CO 2 ) and water (H 2 O). A chemical reaction involves the breaking and forming of chemical bonds. When methane burns, bonds break in the methane and oxygen molecules, and new bonds form in the molecules of carbon dioxide and water. Q: Burning of methane is a type of what, which involves the breaking and forming of bonds? A:

OPTIONS:
- liquid reaction
- physical reaction
- toxic reaction
- chemical reaction

Answer: chemical reaction

Problem: OPTIONS:
- a rainbow
- an element
- the molecule
- the atom
Q: Answer the following question given this paragraph: The emission spectrum of hydrogen is discontinuous. The spectrum is made up of discrete lines representing transitions of the hydrogen electron between specific energy levels within the atom. Q: The spectrum is made up of discrete lines representing transitions of the hydrogen electron between specific energy levels within what? A:
Answer: the atom

Problem:OPTIONS:
- gas
- animal
- fossil
- renewable

Answer the following question given this paragraph: New technologies can be developed. Renewable energy sources emit fewer or no greenhouse gases. These sources are discussed in the chapter Natural Resources . Q: What type energy sources emit fewer or no greenhouse gases? A:
****
A: renewable

Problem:OPTIONS:
- producers
- chimeras
- viruses
- heterotrophs

Answer the following question given this paragraph: Types of organisms that make glucose by photosynthesis are pictured in Figure below . They include plants, plant-like protists such as algae, and some kinds of bacteria. Living things that make glucose are called autotrophs ("self feeders"). All other living things obtain glucose by eating autotrophs (or organisms that eat autotrophs). These living things are called heterotrophs ("other feeders"). Q: What are living things that obtain glucose by eating self feeders called? A:
****
A:
heterotrophs
