Answer the following question given this paragraph: Watch this animation (http://openstaxcollege. org/l/sintestine) that depicts the structure of the small intestine, and, in particular, the villi. Epithelial cells continue the digestion and absorption of nutrients and transport these nutrients to the lymphatic and circulatory systems. In the small intestine, the products of food digestion are absorbed by different structures in the villi. Which structure absorbs and transports fats?. Q: Which cells continue the digestion and absorption of nutrients and transport these nutrients to the lymphatic and circulatory systems? A:

OPTIONS:
- myocyte
- blood cells
- neurons
- epithelial cells

Answer: epithelial cells

Answer the following question given this paragraph: 42.3 | Antibodies By the end of this section, you will be able to: Explain cross-reactivity Describe the structure and function of antibodies Discuss antibody production An antibody, also known as an immunoglobulin (Ig), is a protein that is produced by plasma cells after stimulation by an antigen. Antibodies are the functional basis of humoral immunity. Antibodies occur in the blood, in gastric and mucus secretions, and in breast milk. Antibodies in these bodily fluids can bind pathogens and mark them for destruction by phagocytes before they can infect cells. Q: What protein is produced when a plasma cell is stimulated by antigens? A:
****
A: immunoglobulin

Q: Light from objects at different distances is focused by what part of the eye? A:
OPTIONS:
- iris
- pupil
- meniscus
- lens

Answer: lens

input with options: Answer the following question given this paragraph: A related process to diffusion is the effusion. Effusion is the process of a confined gas escaping through a tiny hole in its container. Effusion can be observed by the fact that a helium-filled balloon will stop floating and sink to the floor after a day or so. This is because the helium gas effuses through tiny pores in the balloon. Both diffusion and effusion are related to the speed at which various gas molecules move. Gases that have a lower molar mass effuse and diffuse at a faster rate than gases that have a higher molar mass. Q: Both diffusion and effusion are related to the speed at which what objects move? A:
OPTIONS:
- electricity
- copper molecules
- solids
- gas molecules
output:
gas molecules
