Answer the following question given this paragraph: Cancer is a disease in which cells grow out of control and form abnormal masses of cells. It is generally caused by mutations in genes that regulate the cell cycle. Because of the mutations, cells with damaged DNA are allowed to divide without limits. Cancer genes can be inherited. You can learn more about hereditary cancer by watching the video at the following link: http://www. youtube. com/watch?v=LWk5FplsKwM (4:29). Q: What is the disease in which cells grow out of control and form abnormal masses? Choices: - bronchitis - diabetes - HIV - cancer A:
cancer
Answer the following question given this paragraph: Many species have a feeding structure, the radula , found only in mollusks. The radula can be thought of as a "tongue-like" structure. The radula is made mostly of chitin. Types of radulae range from structures used to scrape algae off of rocks to the beaks of squid and octopuses. Q: What is the radula made mostly of? Choices: - casein - chlorophyll - schist - chitin A:
chitin
Q: Answer the following question given this paragraph: The image above is one type of electrical fuse. This fuse has a specially designed wire inside glass housing. The wire inside the glass is made of a particular metal and with a particular thickness to give the wire an exact resistance. This resistance will allow passage of normal current plus a marginal percentage more. If, however, the current exceeds the allowed value, the wire in the fuse will heat and melt, thus interrupting current flow through the circuit. The fuse wire is placed in the glass housing and a fuse mount to insulate the melting wire from its surroundings. Any unintended increase in current, such as short circuits, overloading, mismatched loads, or device failure will cause the fuse to burn out protecting the other parts of the circuit from overheating and further damage. Q: What happens to the wire in a fuse if it's current rating is exceed? Choices: - disappears - ignites - sparks - it melts A:
A: it melts
Question: Answer the following question given this paragraph: The alveoli in the lungs are where gas exchange between the air and blood takes place. Each alveolus is surrounded by a network of capillaries. When you inhale, air in the alveoli has a greater concentration of oxygen than does blood in the capillaries. The difference in oxygen concentration causes oxygen to diffuse from the air into the blood. You can see how this occurs in Figure below . Q: Where in the lungs does gas exchange between the air and blood takes place? Choices: - ganglion - left lobe - bronchial tube - alveoli A:
Answer: alveoli

Answer the following question given this paragraph: Puberty is the stage of life when a child becomes sexually mature. Puberty lasts from about 10 to 16 years of age in girls and from about 12 to 18 years of age in boys. In both girls and boys, puberty begins when the pituitary gland signals the gonads (ovaries or testes) to start secreting sex hormones (estrogen in girls, testosterone in boys). Sex hormones, in turn, cause many other changes to take place. Q: What is the name of the stage of life when a child becomes sexually mature? Choices: - adolescence - growth spurt - maturity - puberty A:
**Answer**
puberty
Q: Answer the following question given this paragraph: The molecular mass is the sum of the masses of the atoms in a molecule. Q: What is the sum of the massess of the atoms in a molecule? Choices: - underlying mass - magnetic mass - nuclear mass - molecular mass A:
A: molecular mass
