Q: Lymphatic capillaries are interlaced with the arterioles and venules of which system? A:
OPTIONS:
- skeletal systems
- circulatory system
- atmospheric system
- cardiovascular system
output: cardiovascular system

Q: Answer the following question given this paragraph: Q: Which carrier molecule becomes less effective at binding oxygen as temperature increases? A:

OPTIONS:
- water
- helium
- hydrogen
- hemoglobin

A: hemoglobin

input: OPTIONS:
- proteins
- membranes
- parasites
- antibodies Now, answer this question: Answer the following question given this paragraph: Plasma cells are activated B cells that secrete antibodies. Antibodies are large, Y-shaped proteins that recognize and bind to antigens. Plasma cells are like antibody factories, producing many copies of a single type of antibody. The antibodies travel throughout the body in blood and lymph. Each antibody binds to just one kind of antigen. When it does, it forms an antigen-antibody complex (see Figure below ). The complex flags the antigen-bearing cell for destruction by phagocytosis . Q: What do you call large, y-shaped proteins that recognize and bind to antigens? A:
A:
output: antibodies

Q: Answer the following question given this paragraph: Sound waves are mechanical waves, and mechanical waves can only travel through matter. The matter through which the waves travel is called the medium (plural, media). The Table below gives the speed of sound in several different media. Generally, sound waves travel most quickly through solids, followed by liquids, and then by gases. Particles of matter are closest together in solids and farthest apart in gases. When particles are closer together, they can more quickly pass the energy of vibrations to nearby particles. You can explore the speed of sound in different media at this URL:. Q: What is the matter through which sound waves travel? A:
Answer: medium
