The molecular reaction to produce methanol from iodomethane and sodium hydroxide is shown below. Q: The reaction of an alkyl halide with an inorganic hydroxide base at elevated temperature produces what? Choices: - blood - methane - yeast - an alcohol A:

Q: Answer the following question given this paragraph: Hazardous waste is material that is toxic, chemically active, corrosive, or flammable. Q: Hazardous waste is material that is toxic, chemically active, corrosive, or what? Choices: - inactive - decomposed - organic - flammable A:
A: flammable
Question: Answer the following question given this paragraph: Each Volvox , shown in Figure above , is a colonial organism. It is made up of between 1,000 to 3,000 photosynthetic algae that are grouped together into a hollow sphere. The sphere has a distinct front and back end. The cells have eyespots, which are more developed in the cells near the front. This enables the colony to swim towards light. Q: What do the cells in the front of a volvox typically develop to help swim towards light? Choices: - tumors - sunspots - vertebrates - eyespots A:
Answer: eyespots

Answer the following question given this paragraph: Autoimmune diseases occur when the immune system fails to recognize the body's own molecules as "self," or belonging to the person. Instead, it attacks body cells as though they were dangerous pathogens. There are more than 80 known autoimmune diseases. Recall that regulatory T cells help regulate the immune system. When autoimmune disorders occur, these regulatory T cells fail in their function. This results in damage to various organs and tissues. The type of autoimmune disorder depends on the type of body tissue that is affected. Q: What type of disease occurs when the immune system fails to recognize the body's own molecules? Choices: - gastrointestinal - cardiac - congenital - autoimmune A:
**Answer**
autoimmune

Answer the following question given this paragraph: Monatomic ions form when a single atom gains or loses electrons. For the main group elements, cations are generally formed by removing all of the valence electrons from the atom. Since the numbers of valence electrons for the representative elements are constant within a particular group, all we need is the group number of a given element to know its charge when it becomes a cation. Group 1 elements form ions with a 1+ charge, Group 2 metal ions have a 2+ charge, and the ions of Group 13 elements tend to have a 3+ charge. Heavier p-block metals such as tin and lead are special cases and will be discussed with the transition metal ions. The name of a monatomic cation is the same as the name of the neutral element. For example, the sodium atom (Na) loses a single electron to form the sodium ion (Na + ), while Al 3+ is an aluminum ion. Q: What form when a single atom gains or loses electrons? Choices: - fusional ions - vacuoles ions - carbon atoms - monatomic ions A:
**Answer**
monatomic ions
