Q: Answer the following question given this paragraph: Food allergies occur when the immune system reacts to substances in food as though they were harmful "foreign invaders. " Foods that are most likely to cause allergies are pictured in Figure below , and include nuts, eggs, grains and milk. Symptoms of food allergies often include vomiting and diarrhea. Symptoms of food allergies include itching and swelling of the lips and mouth. More serious symptoms include trouble breathing. In some instances, a food allergy can trigger anaphylaxis, which is an extremely severe reaction. Emergency medical treatment is critical for this condition, which left untreated, can lead to death. Q: What is an extremely severe food allergy reaction? A: | OPTIONS:
- sepsis
- apoptosis
- lymphocytes
- anaphylaxis
A: anaphylaxis

Q: Answer the following question given this paragraph: Compounds like sodium chloride form structures called crystals. A crystal is a rigid framework of many ions locked together in a repeating pattern. Ions are electrically charged forms of atoms. You can see a crystal of sodium chloride in the Figure below . It is made up of many sodium and chloride ions. Q: Compounds like sodium chloride form structures called what? A: | OPTIONS:
- ions
- microorganisms
- hydrocarbons
- crystals
A: crystals

Q: Answer the following question given this paragraph: After a star becomes a red giant, it will take one of several different paths to end its life. Which path is followed by a star after the red giant phase depends on its mass. During the fusion life of a star, its size is the result of a competition between fusion heat pushing the material out and gravity pulling the material in. At the end, gravity always wins. After the star has lived through its red giant stage, the fusion essentially ends (the star runs out of fuel) allowing gravity to collapse the star. Some of the outer layers of material will be blown away and the core becomes smaller and denser. The core will become either a neutron star, a white dwarf, a black dwarf, or a black hole. Q: After what life stage does the fusion inside a star end? A: | OPTIONS:
- blue giant
- yellow dwarf
- white dwarf
- red giant
A: red giant

Q: Answer the following question given this paragraph: An ammeter measures the current traveling through the circuit. They are designed to be connected to the circuit in series, and have an extremely low resistance. If an ammeter were connected in parallel, all of the current would go through the ammeter and very little through any other resistor. As such, it is necessary for the ammeter to be connected in series with the resistors. This allows the ammeter to accurately measure the current flow without causing any disruptions. In the circuit sketched above, the ammeter is . Q: An ammeter must be connected in series with what to allow it to accurately measure the current flow without causing any disruptions? A: | OPTIONS:
- insulators
- configurations
- capacitors
- resistors
A: resistors
