Question: Answer the following question given this paragraph: Leaf Structure and Function The outermost layer of the leaf is the epidermis; it is present on both sides of the leaf and is called the upper and lower epidermis, respectively. Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). The epidermis helps in the regulation of gas exchange. It contains stomata (Figure 30.24): openings through which the exchange of gases takes place. Two guard cells surround each stoma, regulating its opening and closing. Q: The outermost layer of the leaf is the epidermis; it is present on both sides of the leaf and is called the upper and lower epidermis, respectively. botanists call the upper side the adaxial surface (or adaxis) and the lower side this? A:
OPTIONS:
- dorsal surface
- posterior surface
- anterior surface
- abaxial surface (or abaxis)
Answer: abaxial surface (or abaxis)

input with options: Answer the following question given this paragraph: Ecologists look at many factors that help to describe a population. First, ecologists can measure the number of individuals that make up the population, known as population size . They can then determine the population density , which is the number of individuals of the same species in an area. Population density can be expressed as number per area , such as 20 mice/acre, or 50 rabbits/square mile. Q: How is population density expressed? A:
OPTIONS:
- per arable land
- number per household
- arable land per capita
- number per area
output: number per area

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

input: OPTIONS:
- nitrogen
- sulfur
- carbon monoxide
- carbon dioxide Now, answer this question: Answer the following question given this paragraph: Carbon dioxide is the main greenhouse gas causing global warming. There are several possible ways to reduce carbon dioxide emissions. They include cap-and-trade systems, carbon taxes, and carbon sequestration. Q: What is the main greenhouse gas causing global warming? A:
A:
output: carbon dioxide

OPTIONS:
- fertilization
- pregnancy
- copulation
- ovulation

Answer: ovulation

Q: Answer the following question given this paragraph: Bundles of vascular tissue run through the ground tissue of a stem and transport fluids. Plants may vary in how these bundles are arranged. Q: What population on earth is already harming the environment due to less resources to go around? A:

OPTIONS:
- whales
- rats
- insects
- humans

A:
humans
