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? Choices: - the plasma - the substrate - the protein - the membrane A:
(Answer)
the membrane
Ques: 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? Choices: - troposphere - smog - gases - ozone A:
Ans: ozone
(Q).
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? Choices: - plasma - platelet - ferric acid - hemoglobin A:
(A).
hemoglobin
Ques:Answer the following question given this paragraph: Female reproductive structures include the vagina, uterus, ovaries, and fallopian tubes. Q: What structures include the vagina, uterus, ovaries, and fallopian tubes? Choices: - respiration - digestion - skeletal - reproductive A:

Ans:reproductive
Ques:Answer the following question given this paragraph: from the atmosphere at sea level. As a diver descends, the increase in pressure causes the body's air pockets in the ears and lungs to compress; on the ascent, the decrease in pressure causes these air pockets to expand, potentially rupturing eardrums or bursting the lungs. Divers must therefore undergo equalization by adding air to body airspaces on the descent by breathing normally and adding air to the mask by breathing out of the nose or adding air to the ears and sinuses by equalization techniques; the corollary is also true on ascent, divers must release air from the body to maintain equalization. Buoyancy, or the ability to control whether a diver sinks or floats, is controlled by the buoyancy compensator (BCD). If a diver is ascending, the air in his BCD expands because of lower pressure according to Boyle's law (decreasing the pressure of gases increases the volume). The expanding air increases the buoyancy of the diver, and she or he begins to ascend. The diver must vent air from the BCD or risk an uncontrolled ascent that could rupture the lungs. In descending, the increased pressure causes the air in the BCD to compress and the diver sinks much more quickly; the diver must add air to the BCD or risk an uncontrolled descent, facing much higher pressures near the ocean floor. The pressure also impacts how long a diver can stay underwater before ascending. The deeper a diver dives, the more compressed the air that is breathed because of increased pressure: If a diver dives 33 feet, the pressure is 2 ATA and the air would be compressed to one-half of its original volume. The diver uses up available air twice as fast as at the surface. Q: As a diver descends, the increase in pressure causes the body's air pockets in the ears and lungs to do what? Choices: - heat up - expand - blow up - compress A:

Ans:
compress
