Answer the following question given this paragraph: Chemical cells are found in batteries. They produce voltage by means of chemical reactions. Chemical cells have two electrodes, which are strips of different materials, such as zinc and carbon. The electrodes are suspended in an electrolyte. This is a substance that contains free ions, which can carry electric current. The electrolyte may be either a paste, in which case the cell is called a dry cell, or a liquid, in which case the cell is called a wet cell. Flashlight batteries contain dry cells. Car batteries contain wet cells. Q: Batteries produce voltage through what type of reaction? A:
OPTIONS:
- liquid
- non-chemical
- thermal
- chemical

Answer: chemical

Question: Answer the following question given this paragraph: In the health sciences, the concentration of a solution is typically expressed asparts per thousand (ppt), indicated as a proportion. For example, adrenalin, the hormone produced in high-stress situations, is available in a 1:1000 solution, or one gram of adrenalin per 1000 g of solution. The labels on bottles of commercial reagents often describe the contents in terms of mass percentage. Sulfuric acid, for example, is sold as a 95% aqueous solution, or 95 g of H2SO4 per 100 g of solution. Parts per million and parts per billion are used to describe concentrations of highly dilute solutions. These measurements correspond to milligrams and micrograms of solute per kilogram of solution, respectively. For dilute aqueous solutions, this is equal to milligrams and micrograms of solute per liter of solution (assuming a density of 1.0 g/mL). Q: What is the hormone produced in high-stress situations? A:
OPTIONS:
- testosterone
- thyroxine
- somatostatin
- adrenalin
Answer: adrenalin

input with options: Answer the following question given this paragraph: The arrow in Figure above shows that the reaction goes from left to right, from hydrogen and oxygen to water. The reaction can also go in the reverse direction. If an electric current passes through water, water molecules break down into molecules of hydrogen and oxygen. This reaction would be represented by a right-to-left arrow in Figure above . Q: If an electric current passes through water, water molecules break down into molecules of what? A:
OPTIONS:
- carbon and oxygen
- hydrogen and carbon
- oxygen and methane
- hydrogen and oxygen
output: hydrogen and oxygen

Q: Answer the following question given this paragraph: 20.3 | Terrestrial Biomes By the end of this section, you will be able to: Identify the two major abiotic factors that determine the type of terrestrial biome in an area Recognize distinguishing characteristics of each of the eight major terrestrial biomes Earth's biomes can be either terrestrial or aquatic. Terrestrial biomes are based on land, while aquatic biomes include both ocean and freshwater biomes. The eight major terrestrial biomes on Earth are each distinguished by characteristic temperatures and amount of precipitation. Annual totals and fluctuations of precipitation affect the kinds of vegetation and animal life that can exist in broad geographical regions. Temperature variation on a daily and seasonal basis is also important for predicting the geographic distribution of a biome. Since a biome is defined by climate, the same biome can occur in geographically distinct areas with similar climates (Figure 20.18). There are also large areas on Antarctica, Greenland, and in mountain ranges that are covered by permanent glaciers and support very little life. Strictly speaking, these are not considered biomes and in addition to extremes of cold, they are also often deserts with very low precipitation. Q: Terrestrial and aquatic are the two basic categories of what, on earth? A:

OPTIONS:
- substrates
- atmospheres
- dendrites
- biomes

A: biomes

input: OPTIONS:
- windpipe
- nose
- mouth
- lungs Now, answer this question: Answer the following question given this paragraph: Q: Some terrestrial species breathe through their skin and oral cavity because they lack what? A:
A:
output: lungs

Question: Answer the following question given this paragraph: Recall that the only required ingredients needed for photosynthesis are sunlight, carbon dioxide (CO 2 ), and water (H 2 O). From these simple inorganic ingredients, photosynthetic organisms produce the carbohydrate glucose (C 6 H 12 O 6 ), and other complex organic compounds. Essentially, these producers are changing the energy from the sunlight into a usable form of energy. They are also making the oxygen that we breathe. Oxygen is a waste product of photosynthesis. Q: For photosynthesis to begin, the inputs required are sunlight, water, and what? A:
OPTIONS:
- phosphorus dioxide
- methane
- sulfur dioxide
- carbon dioxide
Answer:
carbon dioxide
