- tissue
- collagen
- dendrites
- cilia
Q: Answer the following question given this paragraph: Mucous membranes provide a mechanical barrier at body openings. They also line the respiratory, GI, urinary, and reproductive tracts. Mucous membranes secrete mucus , a slimy substance that traps pathogens. The membranes also have hair-like cilia. The cilia sweep mucus and pathogens toward body openings where they can be removed from the body. When you sneeze or cough, pathogens are removed from the nose and throat (see Figure below ). Tears wash pathogens from the eyes, and urine flushes pathogens out of the urinary tract. You can watch the sweeping action of cilia at the following link: http://mcdb. colorado. edu/courses/2115/units/Other/mucus%20animation. swf . Q: The tiny hair present on mucus membranes is known as? A:
Answer: cilia

Problem:OPTIONS:
- layers
- density
- mass
- dimensions

Answer the following question given this paragraph: The volume of a regularly shaped solid can be calculated from its dimensions. For example, the volume of a rectangular solid is the product of its length, width, and height. Q: The volume of a regularly shaped solid can be calculated from its what? A:
****
A: dimensions

Answer the following question given this paragraph: An electromagnetic wave is a transverse wave that can travel across space as well as through matter. When it travels through space, it doesn't lose energy to a medium as a mechanical wave does. Q: When traveling through space what do mechanical waves lose? A:
OPTIONS:
- Mass
- Speed
- Force
- energy
energy

Answer the following question given this paragraph: Let's briefly review the basics of covalent bonding as they pertain to carbon. Carbon has four valence electrons, which have a 2s 2 2p 2 configuration in isolated carbon atoms. These four electrons allow carbon to form four covalent bonds, which can mean four single bonds or some combination of single, double, and triple bonds. Q: How many valence electrons can be found in a carbon atom? A:
OPTIONS:
- five
- three
- One
- four

Answer: four

Question: Answer the following question given this paragraph: Mammals generate heat mainly by maintaining a high rate of metabolism. Compared with the cells of other animals, the cells of mammals have more mitochondria. Mitochondria are the cell organelles that generate energy. Mammals may also produce little bursts of heat by shivering. Shivering occurs when many muscles all contract slightly at the same time. The muscle contractions generate a small amount of heat. Q: How do mammals generate heat? A:
OPTIONS:
- running around fast
- eating spicy foods
- maintaning low metabolism
- maintaining high metabolism
Answer: maintaining high metabolism

input: OPTIONS:
- cell tube
- occular tube
- peripheral tube
- neural tube Now, answer this question: Answer the following question given this paragraph: called growth factors signal some cells at the edge of the ectoderm to become epidermis cells. The remaining cells in the center form the neural plate. If the signaling by growth factors were disrupted, then the entire ectoderm would differentiate into neural tissue. The neural plate undergoes a series of cell movements where it rolls up and forms a tube called the neural tube, as illustrated in Figure 43.28. In further development, the neural tube will give rise to the brain and the spinal cord. Q: The neural plate undergoes a series of cell movements where it rolls up and forms a tube called what? A:
A:
output:
neural tube
