input with options: Answer the following question given this paragraph: With less ozone in the stratosphere, more UV rays reach the ground. More UV rays increase skin cancer rates. Just a 1 percent loss of ozone causes a 5 percent increase in skin cancer. More UV rays also harm plants and phytoplankton. As a result, they produce less food. This may affect entire ecosystems. Q: More uv rays reach the ground due to a decrease in what layer in the stratosphere? A:
OPTIONS:
- troposphere
- smog
- gases
- ozone
output: ozone

Q: Answer the following question given this paragraph: Normally, electric charge is transferred when electrons leave the outer orbits of the atoms of one body (leaving it positively charged) and move to the surface of another body (causing the new surface to gain a negative net charge). In a plasma all electrons are stripped from the atoms, leaving positively charged ions and free electrons. Q: What do extensive properties depend on the amount of? A:

OPTIONS:
- experimental controls
- sample temperature
- independent variables
- matter in a sample

A: matter in a sample

input: OPTIONS:
- phosphorus
- weathering
- acid
- stress Now, answer this question: Answer the following question given this paragraph: The amount of stress on a rock may be greater than the rock's strength. In that case, the rock will change and deform ( Figure below ). Deep within the Earth, the pressure is very great. A rock behaves like a stretched rubber band. When the stress stops, the rock goes back to its original shape. If more stress is applied to the rock, it bends and flows. It does not return to its original shape. Near the surface, if the stress continues, the rock will fracture and break. Q: What is applied to a rock to make it bend and flow? A:
A:
output: stress

Answer the following question given this paragraph: Prokaryotic cells are extremely small and have a variety of shapes. Most have flagella and a cell wall. They have several other cell structures as well. Their DNA exists as large and small loops. Some prokaryotes form biofilms, which are colonies of cells stuck to a surface. Q: What are colonies of cells stuck to a surface called? A:

OPTIONS:
- membranes
- cellular coating
- membranes
- biofilms

Answer: biofilms

Problem: OPTIONS:
- mitochondria
- vacuoles
- plasma membrane
- microfilaments
Q: Answer the following question given this paragraph: Figure 4.22 Microfilaments thicken the cortex around the inner edge of a cell; like rubber bands, they resist tension. Microtubules are found in the interior of the cell where they maintain cell shape by resisting compressive forces. Intermediate filaments are found throughout the cell and hold organelles in place. Q: What thickens the cortex around the inner edge of a cell? A:
Answer: microfilaments

Answer the following question given this paragraph: Q: What evolutionary concept characterizes a species by body shape and other structural features? A:

OPTIONS:
- geologic species concept
- spontaneous evolution theory
- primary speciation
- morphological species concept

Answer:
morphological species concept
