Answer the following question given this paragraph: The skin is the major organ of the integumentary system , which also includes the nails and hair. In fact, the skin is the body's largest organ, and a remarkable one at that. Consider these skin facts. The average square inch (6.5 cm 2 ) of skin has 20 blood vessels, 650 sweat glands, and more than a thousand nerve endings. It also has an incredible 60,000 pigment-producing cells. All of these structures are packed into a stack of cells that is just 2 mm thick, or about as thick as the cover of a book. Q: What organ system consists of the skin, nails and hair? A:

OPTIONS:
- nervous system
- digestive system
- endocrine system
- integumentary system

Answer: integumentary system

Problem: OPTIONS:
- hydrocarbon
- sulfur
- base
- acid
Q: Answer the following question given this paragraph: An acid is an ionic compound that produces positive hydrogen ions when dissolved in water. Acids taste sour and turn blue litmus paper red. Q: What is the term for an ionic compound that produces positive hydrogen ions when dissolved in water? A:
Answer: acid

Problem:OPTIONS:
- erosion
- volcanoes
- storms
- earthquakes

Answer the following question given this paragraph: When an earthquake will occur is much more difficult to predict. Stress on a fault builds up at the same rate over time. So earthquakes should occur at regular intervals. But, so far, scientists cannot predict when quakes will occur even to within a few years. Around Parkfield, California, an earthquake of magnitude 6.0 or higher occurs about every 22 years. So seismologists predicted that one would strike in 1993. But that quake came in 200411 years late ( Figure below ). Q: Stress building up at the same rate over time at a fault causes what phenomenon? A:
****
A: earthquakes

Answer the following question given this paragraph: Pathways of Hormone Action The message a hormone sends is received by a hormone receptor, a protein located either inside the cell or within the cell membrane. The receptor will process the message by initiating other signaling events or cellular mechanisms that result in the target cell's response. Hormone receptors recognize molecules with specific shapes and side groups, and respond only to those hormones that are recognized. The same type of receptor may be located on cells in different body tissues, and trigger somewhat different responses. Thus, the response triggered by a hormone depends not only on the hormone, but also on the target cell. Once the target cell receives the hormone signal, it can respond in a variety of ways. The response may include the stimulation of protein synthesis, activation or deactivation of enzymes, alteration in the permeability of the cell membrane, altered rates of mitosis and cell growth, and stimulation of the secretion of products. Moreover, a single hormone may be capable of inducing different responses in a given cell. Q: Receptors for what chemical messengers recognize molecules with specific shapes and side groups, and respond only to those that are recognized? A:
OPTIONS:
- acids
- chromosomes
- enzymes
- hormones
hormones

Answer the following question given this paragraph: The branch of biology that studies animal behavior is called ethology. Ethologists usually study how animals behave in their natural environment. They try to determine the cause of behaviors, how behaviors develop, and how and why behaviors evolve. Q: Which branch of biology studies animal behavior? A:
OPTIONS:
- microbiology
- anthropology
- embryology
- ethology

Answer:
ethology
