Q: Answer the following question given this paragraph: Reactivity is how likely an element is to react chemically with other elements. Some nonmetals are extremely reactive, whereas others are completely nonreactive. What explains this variation in nonmetals? The answer is their number of valence electrons. These are the electrons in the outer energy level of an atom that are involved in interactions with other atoms. Let's look at two examples of nonmetals, fluorine and neon. Simple atomic models of these two elements are shown in the Figure below . Q: The number of valence electrons determines variation of what property in nonmetals? A:

OPTIONS:
- permeability
- density
- turbidity
- reactivity

A: reactivity

input: OPTIONS:
- pulp
- cambium
- vascular tissue
- cellulose Now, answer this question: Answer the following question given this paragraph: Cellulose is another polymer of glucose, consisting of anywhere from hundreds to over ten thousand monomers. It is the structural component of the cell walls of green plants and is the single most common organic molecule on Earth. Roughly 33% of all plant matter is cellulose. The linkage structure in cellulose is different than that of starch, and cellulose is indigestible except by a few microorganisms that live in the digestive tracts of cattle and termites. The figure below shows a triple strand of cellulose. There is no branching and the fibers adopt a very stiff rod-like structure with numerous hydrogen bonds between the fibers adding to its strength. Cellulose is the main component of paper, cardboard, and textiles made from cotton, linen, and other plant fibers. Q: What is the main component of paper, cardboard, and textiles made from cotton, linen, and other plant fibers? A:
A:
output: cellulose

Answer the following question given this paragraph: Unlike ionic compounds, covalent compounds do not have freely moving electrons, so they cannot conduct electricity. Q: Unlike ionic compounds, covalent compounds do not have freely moving what? A:

OPTIONS:
- neutrons
- atoms
- Nuclei.
- electrons

Answer: electrons

Problem: OPTIONS:
- an ovum
- a sperm
- an egg
- an embryo
Q: Answer the following question given this paragraph: Pollination occurs when pollen is transferred from a male to female cone. If sperm then travel from the pollen to an egg so fertilization can occur, a diploid zygote results. The zygote develops into an embryo within a seed, which forms from the ovule inside the female cone. If the seed germinates, it may grow into a mature sporophyte tree, which repeats the cycle. Q: If pollination occurs, what does the zygote develop into? A:
Answer: an embryo

Problem:OPTIONS:
- energy
- precipitation
- friction
- temperature

Answer the following question given this paragraph: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. Q: What is the measure of kinetic energy of the particles in matter? A:
****
A: temperature

Problem:OPTIONS:
- middle
- upper
- outer
- inner

Answer the following question given this paragraph: Figure 14.5 Structures of the Ear The external ear contains the auricle, ear canal, and tympanic membrane. The middle ear contains the ossicles and is connected to the pharynx by the Eustachian tube. The inner ear contains the cochlea and vestibule, which are responsible for audition and equilibrium, respectively. Q: The cochlea and vestibul make up what part of the ear? A:
****
A:
inner
