Answer the following question given this paragraph: 4. Ions move through the membrane to maintain electrical neutrality in the cell. In the cell illustrated above, sulfate ions will move from the copper side to the zinc side to compensate for the decrease in Cu 2+ and the increase in Zn 2+ . Q: Ions move through what to maintain electrical neutrality in the cell? A:
OPTIONS:
- the plasma
- the substrate
- the protein
- the membrane
the membrane

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

Answer: ozone

Question: Answer the following question given this paragraph: Hemoglobin is the iron-containing oxygen-transport protein in the red blood cells of all vertebrates. The hemoglobin molecule is an assembly of four globular protein subunits, each tightly associated with a non-protein heme group. The heme group binds to the iron ion. The most common hemoglobin is hemoglobin A, a tetramer consisting of two alpha and two beta subunits, denoted as 22. Q: What is the name of the iron-containing oxygen-transport protein in the red blood cells of all vertebrates? A:
OPTIONS:
- plasma
- platelet
- ferric acid
- hemoglobin
Answer: hemoglobin

Answer the following question given this paragraph: A familiar example may help you understand the vibrating electric and magnetic fields that make up electromagnetic waves. Consider a bar magnet, like the one in the Figure below . The magnet exerts magnetic force over an area all around it. This area is called a magnetic field. The field lines in the diagram represent the direction and location of the magnetic force. Because of the field surrounding a magnet, it can exert force on objects without touching them. They just have to be within its magnetic field. Q: A magnet can exert force on objects without touching them, as long as they are within what? A:
OPTIONS:
- audio field
- molecular field
- gravitational field
- magnetic field
magnetic field
