input: OPTIONS:
- nostrils
- lungs
- pores
- gills Now, answer this question: Answer the following question given this paragraph: Amphibian skin contains keratin, a protein that is also found in the outer covering of most other four-legged vertebrates. The keratin in amphibians is not too tough to allow gases and water to pass through their skin. Most amphibians breathe with gills as larvae and with lungs as adults. However, extra oxygen is absorbed through the skin. Q: Most amphibians breathe with these as larvae? A:
A:
output: gills

Answer the following question given this paragraph: Ground type. Solid bedrock vibrates less than soft sediments, so there is less damage on bedrock. Sometimes sediments become saturated with water. They then undergo liquefaction and become like quicksand ( Figure below ). Soil on a hillside may become a landslide. Q: Solid bedrock vibrates less and therefore does less of what to bedrock? A:

OPTIONS:
- block
- dampen
- butress
- damage

Answer: damage

Problem: OPTIONS:
- veins
- capillaries
- cilia
- arteries
Q: Answer the following question given this paragraph: The blood vessels are an important part of the cardiovascular system. They connect the heart to every cell in the body. Arteries carry blood away from the heart, while veins return blood to the heart ( Figure below ). Q: In the cardiovascular system, what blood vessels carry blood away from the heart? A:
Answer: arteries

Problem:OPTIONS:
- magnetic force
- humidity
- water
- air

Answer the following question given this paragraph: 11.4 Variation of Pressure with Depth in a Fluid If your ears have ever popped on a plane flight or ached during a deep dive in a swimming pool, you have experienced the effect of depth on pressure in a fluid. At the Earth's surface, the air pressure exerted on you is a result of the weight of air above you. This pressure is reduced as you climb up in altitude and the weight of air above you decreases. Under water, the pressure exerted on you increases with increasing depth. In this case, the pressure being exerted upon you is a result of both the weight of water above you and that of the atmosphere above you. You may notice an air pressure change on an elevator ride that transports you many stories, but you need only dive a meter or so below the surface of a pool to feel a pressure increase. The difference is that water is much denser than air, about 775 times as dense. Consider the container in Figure 11.10. Its bottom supports the weight of the fluid in it. Let us calculate the pressure exerted on the bottom by the weight of the fluid. That pressure is the weight of the fluid mg divided by the area A supporting it (the area of the bottom of the container):. Q: At the earth's surface, the air pressure exerted on you is a result of the weight of what above you? A:
****
A: air

Answer the following question given this paragraph: A Mendelian trait is a trait that is controlled by a single gene that has two alleles. One of these alleles is dominant and the other is recessive. Many inheritable conditions in humans are passed to offspring in a simple Mendelian fashion. Medical professionals use Mendel's laws to predict and understand the inheritance of certain traits in their patients. Also, farmers, animal breeders, and horticulturists who breed organisms can predict outcomes of crosses by understanding Mendelian inheritance and probability. Q: A trait controlled by a single gene that has two alleles is given what name, after the scientist who studied inheritance? A:
OPTIONS:
- darwinian trait
- rosilin trait
- carlinian trait
- mendelian trait
mendelian trait

Answer the following question given this paragraph: Matter has both physical and chemical properties. Physical properties can be measured or observed without matter changing to a different substance. Q: What are the two types of properties that matter has? A:
OPTIONS:
- nature and purpose
- composition and weight
- size and shape
- physical and chemical

Answer:
physical and chemical
