Answer the following question given this paragraph: Air pollution is another significant cause of respiratory disease. The quality of the air you breathe can affect the health of your lungs. Asthma, heart and lung diseases, allergies, and several types of cancers are all linked to air quality. Air pollution is not just found outdoors; indoor air pollution can also be responsible for health problems. Q: Air pollution can cause disease of what system by affecting the health of your lungs? Choices: - excretory - digestive - cardiac - respiratory A:
respiratory
Q: Answer the following question given this paragraph: A genetic disorder that is caused by a mutation can be inherited. Therefore, people with a genetic disorder in their family may be concerned about having children with the disorder. Professionals known as genetic counselors can help them understand the risks of their children being affected. If they decide to have children, they may be advised to have prenatal ("before birth") testing to see if the fetus has any genetic abnormalities. One method of prenatal testing is amniocentesis . In this procedure, a few fetal cells are extracted from the fluid surrounding the fetus, and the fetal chromosomes are examined. Q: What measure is resorted to by people who wish to screen out genetic abnormalities in the fetus? Choices: - contraceptive use - in vitro fertilization - stem cell therapy - prenatal testing A:
A: prenatal testing
Question: Answer the following question given this paragraph: Q: What substances are secreted by specialized cells usually located in endocrine glands? Choices: - lipids - protein - acid - hormones A:
Answer: hormones

Answer the following question given this paragraph: Each separate substance in a medium, such as the extracellular fluid, has its own concentration gradient, independent of the concentration gradients of other materials. Additionally, each substance will diffuse according to that gradient. Several factors affect the rate of diffusion. Extent of the concentration gradient: The greater the difference in concentration, the more rapid the diffusion. The closer the distribution of the material gets to equilibrium, the slower the rate of diffusion becomes. Mass of the molecules diffusing: More massive molecules move more slowly, because it is more difficult for them to move between the molecules of the substance they are moving through; therefore, they diffuse more slowly. Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Solvent density: As the density of the solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. Q: In a medium, the closer the distribution of the material gets to what state, the slower the rate of diffusion becomes? Choices: - erosion - gas - elastic - equilibrium A:
**Answer**
equilibrium
