Answer the following question given this paragraph: As a child, you may have made suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water, known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible (or that can be seen with a magnifying glass). They are cloudy, and the suspended particles settle out after mixing. On the other hand, when we make a solution, we prepare a homogeneous mixture in which no settling occurs and in which the dissolved species are molecules or ions. Solutions exhibit completely different behavior from suspensions. A solution may be colored, but it is transparent, the molecules or ions are invisible, and they do not settle out on standing. A group of mixtures called colloids (or colloidal dispersions) exhibit properties intermediate between those of suspensions and solutions (Figure 11.30). The particles in a colloid are larger than most simple molecules; however, colloidal particles are small enough that they do not settle out upon standing. Q: Distinct from a suspension, a solution is considered what type of mixture? A:
OPTIONS:
- gaseous
- continuous
- heterogeneous
- homogeneous
homogeneous

Answer the following question given this paragraph: Because they cannot escape the container, the vapor molecules above the surface of the liquid exert a pressure on the walls of the container. The vapor pressure is a measure of the presure (force per unit area) exerted by a gas above a liquid in a sealed container. Vapor pressure is a property of a liquid based on the strength of its intermolecular forces. A liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. A liquid with stronger intermolecular forces does not evaporate easily and thus has a lower vapor pressure. For example, diethyl ether is a nonpolar liquid with weak dispersion forces. Its vapor pressure at 20C is 58.96 kPa. Water is a polar liquid whose molecules are attracted to one another by relatively strong hydrogen bonding. The vapor pressure of water at 20C is only 2.33 kPa, far less than that of diethyl ether. Q: What term describes a property of a liquid based on the strength of its intermolecular forces? A:
OPTIONS:
- analogous pressure
- cellular pressure
- tissue pressure
- vapor pressure

Answer: vapor pressure

Question: Answer the following question given this paragraph: Symptoms of chlamydia may include a burning sensation during urination and a discharge from the vagina or penis. Chlamydia can be cured with antibiotics , but often there are no symptoms, so people do not seek treatment. Untreated chlamydia can lead to more serious problems, such as pelvic inflammatory disease (PID) . This is an infection of the uterus, fallopian tubes, and/or ovaries. It can scar a woman's reproductive organs and make it difficult for her to become pregnant. Q: Untreated chlamydia can lead to pelvic inflammatory disease, which affects what organ system? A:
OPTIONS:
- endocrine system
- nervous system
- circulatory system
- female reproductive system
Answer: female reproductive system

input with options: Answer the following question given this paragraph: The kidneys are a pair of bean-shaped organs just above the waist. A cross-section of a kidney is shown in Figure below . The function of the kidney is to filter blood and form urine. Urine is the liquid waste product of the body that is excreted by the urinary system. Nephrons are the structural and functional units of the kidneys. A single kidney may have more than a million nephrons!. Q: What is the pair of bean-shaped organs situated just above the waist? A:
OPTIONS:
- pancreas
- aorta
- lungs
- kidneys
output: kidneys

Q: Answer the following question given this paragraph: Every moment of every day is a field trip to gravity. Gravity is everywhere! You have a gravitational attraction to your dog. You have one to your pencil. You even have one to your school principal! These gravitational attractions are very small compared with the most important one you have. This is your gravitational attraction to Earth. It's what keeps you from floating off into space. Gravity holds our planet together. Gravity keeps Earth orbiting the Sun. We wouldn't be here without gravity. Q: What keeps the earth orbiting the sun? A:

OPTIONS:
- variation
- inertia
- speed
- gravity

A: gravity

Answer the following question given this paragraph: There are two types of cellular respiration (see Cellular Respiration concept): aerobic and anaerobic. One occurs in the presence of oxygen ( aerobic ), and one occurs in the absence of oxygen ( anaerobic ). Both begin with glycolysis - the splitting of glucose. Q: What type of cellular respiration occurs in the presence of oxygen? A:
OPTIONS:
- hyperbaric
- anaerobic
- extracellular
- aerobic
aerobic
