Problem:OPTIONS:
- shell electrons
- positrons
- covalence electrons
- valence electrons

Answer the following question given this paragraph: Both fluorine and lithium are highly reactive elements because of their number of valence electrons. Fluorine will readily gain one electron and lithium will just as readily give up one electron to become more stable. In fact, lithium and fluorine will react together as shown in the Figure below . When the two elements react, lithium transfers its one "extra" electron to fluorine. Q: Both fluorine and lithium are highly reactive elements because of their number of what? A:
****
A: valence electrons

Answer the following question given this paragraph: All objects in the universe have an attraction to each other. This attraction is known as gravity ( Figure below ). The strength of the force of gravity depends on two things. One is the mass of the objects. The other is the distance between the objects. As an object's mass increases, the attraction increases. As the distance between the objects increases, the attraction decreases. Q: The attraction between all objects in the universe is known as ______. A:
OPTIONS:
- variation
- electricity
- magnetism
- gravity
gravity

Answer the following question given this paragraph: Transport vesicles are part of the endomembrane system. They are able to move molecules such as proteins between locations inside the cell. For example, transport vesicles move proteins from the rough endoplasmic reticulum to the Golgi apparatus. Q: Transport vesicles move what type of molecules from the rough endoplasmic reticulum to the golgi apparatus? A:
OPTIONS:
- acids
- lipids
- hormones
- proteins

Answer: proteins

Question: Answer the following question given this paragraph: The trillions of red blood cells in blood plasma carry oxygen. Red blood cells contain hemoglobin , a protein with iron that binds with oxygen. Red blood cells are made in the marrow of long bones, rib bones, the skull, and the vertebrae. These cells survive for about 120 days, and then they are destroyed. Mature red blood cells lack a nucleus and other organelles, allowing for more hemoglobin, and therefore more oxygen to be carried by each cell. Q: What is the protein that carries iron that binds with oxygen in red blood cells? A:
OPTIONS:
- keratin
- potassium
- insulin
- hemoglobin
Answer: hemoglobin

input with options: Answer the following question given this paragraph: Q: These types of cella support young, growing parts of a plant? A:
OPTIONS:
- pinworm cells
- epidermal cells
- angular cells
- collenchyma cells
output: collenchyma cells

Problem: OPTIONS:
- marble
- cortex
- stack
- mantle
Q: Answer the following question given this paragraph: A mantle , or fold of the outer skin lining the shell. The mantle often releases calcium carbonate, which creates an external shell, just like the ones you find on the beach. The shell is made of chitin , a tough, semitransparent substance. Q: What is a fold of the outer skin lining the shell called? A:
Answer:
mantle
