Answer the following question given this paragraph: 18.4 Leukocytes and Platelets Leukocytes function in body defenses. They squeeze out of the walls of blood vessels through emigration or diapedesis, then may move through tissue fluid or become attached to various organs where they fight against pathogenic organisms, diseased cells, or other threats to health. Granular leukocytes, which include neutrophils, eosinophils, and basophils, originate with myeloid stem cells, as do the agranular monocytes. The other agranular leukocytes, NK cells, B cells, and T cells, arise from the lymphoid stem cell line. The most abundant leukocytes are the neutrophils, which are first responders to infections, especially with bacteria. About 2030 percent of all leukocytes are lymphocytes, which are critical to the body's defense against specific threats. Leukemia and lymphoma are malignancies involving leukocytes. Platelets are fragments of cells known as megakaryocytes that dwell within the bone marrow. While many platelets are stored in the spleen, others enter the circulation and are essential for hemostasis; they also produce several growth factors important for repair and healing. Q: Which leukocytes are first to respond to bacterial infections? A:
OPTIONS:
- chemocytes
- erythrocytes
- microcytes
- neutrophils
neutrophils

Answer the following question given this paragraph: This teakettle is made of aluminum except for its handle, which is made of plastic. Aluminum is a good conductor of heat. It conducts heat from the flames on the range to the water inside the kettle, so the water heats quickly. Plastic, on the other hand, is not a good conductor of heat. It stays cool enough to touch even when the rest of the teakettle becomes very hot. Q: Why wouldn't a teakettle have an aluminum handle? A:
OPTIONS:
- it absorbs light
- it isn't washable
- it is magnetic
- it conducts heat

Answer: it conducts heat

Question: Answer the following question given this paragraph: Organ systems are organized into the organism. The different organ systems work together to carry out all the life functions of the individual. For example, cardiovascular and respiratory systems work together to provide the individual with oxygen and rid it of carbon dioxide. Q: The different types of what systems work together to carry out all the life functions of the individual? A:
OPTIONS:
- maturation systems
- digestive systems
- heartbeat systems
- organ systems
Answer: organ systems

input with options: Answer the following question given this paragraph: The urinary system controls the amount of water in the body and removes wastes. Any problem with the urinary system can also affect many other body systems. Q: Which human body system controls the amount of water in the body and removes wastes? A:
OPTIONS:
- lymphatic system
- mucous system
- digestive system
- urinary system
output: urinary system

Q: Answer the following question given this paragraph: Q: Which region is just posterior to the mouth? A:

OPTIONS:
- the esophagus
- the duodenum
- the diaphragm
- the pharynx

A: the pharynx

Answer the following question given this paragraph: Temperature is a measure of the average kinetic energy of molecules. Consider a mixture of hydrogen and oxygen gas at a certain temperature. Use the formula for kinetic energy to explain why the hydrogen molecules move faster than the oxygen molecules. Then explain why there's no hydrogen in the earth's atmosphere, and why the moon has no atmosphere at all. Q: What property is a measure of the average kinetic energy of molecules? A:
OPTIONS:
- mass
- velocity
- density
- temperature
