Answer the following question given this paragraph: 5.3 Active Transport The combined gradient that affects an ion includes its concentration gradient and its electrical gradient. A positive ion, for example, might tend to diffuse into a new area, down its concentration gradient, but if it is diffusing into an area of net positive charge, its diffusion will be hampered by its electrical gradient. When dealing with ions in aqueous solutions, a combination of the electrochemical and concentration gradients, rather than just the concentration gradient alone, must be considered. Living cells need certain substances that exist inside the cell in concentrations greater than they exist in the extracellular space. Moving substances up their electrochemical gradients requires energy from the cell. Active transport uses energy stored in ATP to fuel this transport. Active transport of small molecular-sized materials uses integral proteins in the cell membrane to move the materials: These proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action. In co-transport (or secondary active transport), energy from primary transport can be used to move another substance into the cell and up its concentration gradient. Q: The combined gradient that affects an ion includes its concentration gradient and its what? A:
****
A: electrical gradient

Answer the following question given this paragraph: Q: Red-green color blindness is an example of a sex-linked condition caused by what? A:
OPTIONS:
- phenotype
- dominant gene
- genetic disorder
- recessive allele
recessive allele

Answer the following question given this paragraph: Long-term or high-dose exposure to radiation can harm both living and nonliving things. Radiation knocks electrons out of atoms and changes them to ions. It also breaks bonds in DNA and other compounds in living things. One source of radiation that is especially dangerous to people is radon. Radon is a radioactive gas that forms in rocks underground. It can seep into basements and get trapped inside buildings. Then it may build up and become harmful to people who breathe it. Long-term exposure to radon can cause lung cancer. Q: This knocks electrons from atoms and turns them into ions? A:
OPTIONS:
- convection
- chemical reactions
- evaporation
- radiation

Answer: radiation

Question: Answer the following question given this paragraph: Type 2 diabetes is much more common than type 1 diabetes. Type 2 diabetes occurs when body cells no longer respond normally to insulin. The pancreas still makes insulin, but the cells of the body can't use it. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes. This type of diabetes usually develops in adulthood. However, it is becoming more common in teens and children because more young people are overweight now than ever before. Q: Which type of diabetes is more common? A:
OPTIONS:
- gestational diabetes
- juvenile diabetes
- type 1
- type 2
Answer: type 2

input with options: Answer the following question given this paragraph: A concave lens is thicker at the edges than it is in the middle. You can see the shape of a concave lens in the Figure below . From the diagram, it's clear that the lens causes rays of light to diverge, or spread apart, as they pass through it. Note that the image formed by a concave lens is on the same side of the lens as the object. It is also smaller than the object and right-side up. However, it isn't a real image. It is a virtual image. Your brain "tricks" you into seeing an image there. The light rays actually pass through the glass to the other side and spread out in all directions. You can explore the formation of images by a concave lens at this URL: http://phet. colorado. edu/sims/geometric-optics/geometric-optics_en. html. Q: A lens of what shape causes rays of light to diverge, or spread apart, as they pass through it? A:
OPTIONS:
- convex
- flat
- elongated
- concave
output: concave

Problem: OPTIONS:
- experiment
- conclusion
- theory
- hypothesis
Q: Answer the following question given this paragraph: After doing the research, the farmer will try to answer the question. She might think, "If I don't plow my fields, I will lose less soil than if I do plow the fields. Plowing disrupts the soil and breaks up roots that help hold soil in place. " This answer to her question is a hypothesis . A hypothesis is a reasonable explanation. A hypothesis can be tested. It may be the right answer, it may be a wrong answer, but it must be testable. Once she has a hypothesis, the next step is to do experiments to test the hypothesis. A hypothesis can be proved or disproved by testing. If a hypothesis is repeatedly tested and shown to be true, then scientists call it a theory . Q: What is another name for a reasonable explanation for something that might be formed near the beginning of a scientific inquiry into a problem? A:
Answer:
hypothesis
