Answer the following question given this paragraph: Hair serves many functions such as acting as a filter and keeping the body warm. Q: What mammalian feature serves functions such as filtration and keeping the body warm? A:
OPTIONS:
- shivering
- sensory organs
- sweat
- hair
hair

Answer the following question given this paragraph: Catalysts interact with reactants so the reaction can occur by an alternate pathway that has a lower activation energy. Activation energy is the energy needed to start a reaction. When activation energy is lower, more reactant particles have enough energy to react so the reaction goes faster. Many catalysts work like the one in the Figure below . (You can see an animated version at the following URL. ) The catalyst brings the reactants together by temporarily bonding with them. This makes it easier and quicker for the reactants to react together. Notice how the catalyst is released by the product molecule at the end of the reaction. Q: What is the energy needed to start a reaction between catalysts and reactants called? A:
OPTIONS:
- reaction energy
- decomposition energy
- conductivity energy
- activation energy

Answer: activation energy

Question: Answer the following question given this paragraph: Milk and other dairy foods are not the only sources of calcium. This important nutrient is also found in green leafy vegetables, broccoli, and intact salmon and canned sardines with their soft bones. Nuts, beans, seeds, and shellfish provide calcium in smaller quantities. Except for fatty fish like salmon and tuna, or fortified milk or cereal, vitamin D is not found naturally in many foods. The action of sunlight on the skin triggers the body to produce its own vitamin D (Figure 6.22), but many people, especially those of darker complexion and those living in northern latitudes where the sun's rays are not as strong, are deficient in vitamin D. In cases of deficiency, a doctor can prescribe a vitamin D supplement. Q: The action of sunlight on the skin triggers the body to produce what vitamin? A:
OPTIONS:
- Vitamin A
- metabolic d
- tissue d
- vitamin d
Answer: vitamin d

input with options: Answer the following question given this paragraph: Channel proteins provide an open channel or passageway through the cell membrane for molecules to move across. Many channel proteins allow the diffusion of ions. Ions are charged atoms. The charge makes it difficult to cross the cell membrane without assistance. Channel proteins are specific for the molecule they transport. For example a sodium ion crosses the membrane through a channel protein specific for sodium ions. Q: Ions are charged what? A:
OPTIONS:
- molecules
- protons
- isotopes
- atoms
output: atoms

Q: Answer the following question given this paragraph: Immovable joints allow no movement because the bones at these joints are held securely together by dense collagen. The bones of the skull are connected by immovable joints. Q: The bones of the skull are connected by what type of joints? A:

OPTIONS:
- semi-mobile
- pivoting
- adjustable
- immovable

A: immovable

Answer the following question given this paragraph: To balance a nuclear reaction. The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements. The resulting daughter nuclei have a lower mass and are lower in energy (more stable) than the parent nucleus that decayed. In contrast, in anuclear transmutation reaction, a nucleus reacts with a subatomic particle or another nucleus to form a product nucleus that is more massive than the. Q: When an unstable nucleus emits radiation and is transformed into the nucleus of other elements this is called? A:
OPTIONS:
- naturally decay
- explosive decay
- fusion decay
- radioactive decay
radioactive decay
