Answer the following question given this paragraph: Mollusks are invertebrates such as snails, scallops, and squids. They have a hard outer shell. There is a layer of tissue called the mantle between the shell and the body. Most mollusks have tentacles for feeding and sensing, and many have a muscular foot. Mollusks also have a coelom, a complete digestive system, and specialized organs for excretion. The majority of mollusks live in the ocean. Different classes of mollusks have different ways of obtaining food. Q: Snails, scallops, and squids are what type of invertebrate? A:

OPTIONS:
- crustacean
- algae
- arthropod
- mollusk

Answer: mollusk

Problem: OPTIONS:
- electron count
- atomic mass
- real number
- atomic number
Q: Answer the following question given this paragraph: The type of atom is determined by the atomic number (i. e. the number of protons). The atomic mass of an atom is approximately the number of protons plus the number of neutrons. Typically, the atomic mass listed in a periodic table is an average, weighted by the natural abundances of different isotopes. Q: Adding the number of protons plus the number of neutrons in an atom, decides it's approximate mass, what is another word for this value? A:
Answer: atomic number

Problem:OPTIONS:
- sublimation
- freezing
- melting
- vaporization

Answer the following question given this paragraph: The process in which a liquid boils and changes to a gas is called vaporization . The temperature at which a liquid boils is its boiling point. The boiling point of water is 100C (212F). Other types of matter may have higher or lower boiling points. For example, the boiling point of table salt is 1413C. The boiling point of nitrogen is -196C. Q: What is the process in which a liquid boils and changes to a gas? A:
****
A: vaporization

Answer the following question given this paragraph: Living things depend on catalysts to speed up many chemical reactions inside their cells. Catalysts in living things are called enzymes. Enzymes may be extremely effective. A reaction that takes a split second to occur with an enzyme might take billions of years without it!. Q: What speeds up chemical reactions inside cells? A:
OPTIONS:
- nucleus
- inhibitors
- electrodes
- catalysts
catalysts
