Answer the following question given this paragraph: Antibodies also mark pathogens for destruction by phagocytic cells, such as macrophages or neutrophils, because phagocytic cells are highly attracted to macromolecules complexed with antibodies. Phagocytic enhancement by antibodies is called opsonization. In a process called complement fixation, IgM and IgG in serum bind to antigens and provide docking sites onto which sequential complement proteins can bind. The combination of antibodies and complement enhances opsonization even further and promotes rapid clearing of pathogens. Affinity, Avidity, and Cross Reactivity Not all antibodies bind with the same strength, specificity, and stability. In fact, antibodies exhibit different affinities (attraction) depending on the molecular complementarity between antigen and antibody molecules, as illustrated in Figure 42.25. An antibody with a higher affinity for a particular antigen would bind more strongly and stably, and thus would be expected to present a more challenging defense against the pathogen corresponding to the specific antigen. Q: Antibodies also mark pathogens for destruction by which cells? A:
OPTIONS:
- interferons
- leukocytes
- platelets
- phagocytic
phagocytic

Question: Answer the following question given this paragraph: Most digestive enzymes are secreted into the GI tract by organs of the GI tract or from a nearby gland named the pancreas. Figure below shows where the pancreas is located. The figure also shows the locations of the liver and gall bladder. These organs produce or store other digestive secretions. Q: What are secreted into the gi tract by organs of the gi tract or from a nearby gland named the pancreas? A:
OPTIONS:

- insulin and pepsin
- bile
- digestive enzymes
Answer: digestive enzymes

input with options: Answer the following question given this paragraph: 85 million sperm per day are produced. per testicle. That's 170,000,000 every day. This means that a single male may produce more than a quadrillion (1,000,000,000,000) sperm cells in his lifetime! But it only takes one to fertilize an egg. Q: How many sperm does it take to fertilize an egg? A:
OPTIONS:
- ten
- five
- two
- one
output: one

Problem: OPTIONS:
- stationary energy
- molecular energy
- thermal energy
- mechanical energy
Q: Answer the following question given this paragraph: Mechanical energy is the energy of an object that is moving or has the potential to move. It is the sum of an object's kinetic and potential energy. In Figure below , the basketball has mechanical energy because it is moving. The arrow in the same figure has mechanical energy because it has the potential to move due to the elasticity of the bow. What are some other examples of mechanical energy?. Q: What term describes the energy of an object that is moving or has the potential to move? A:
Answer:
mechanical energy
