Answer the following question given this paragraph: Ammeters measure the current through a resistor. Q: What is used to measure current through a resistor? Choices: - thermometers - spectrographs - microscopes - ammeters A:
ammeters
Answer the following question given this paragraph: Texture indicates how the magma cooled. Magma that cools rapidly has small or no visible crystals. Magma that cools slowly has large crystals; reference the Table above for the type of rock, the amount of silica it has, and examples. Q: When magma cools slowly, what texture does it have? Choices: - large squares - large gases - small circles - large crystals A:
large crystals
Q: Answer the following question given this paragraph: There are three main ways that molecules can pass through a phospholipid membrane. The first way requires no energy input by the cell and is called passive transport. The second way requires that the cell uses energy to pull in or pump out certain molecules and ions and is called active transport. The third way is through vesicle transport, in which large molecules are moved across the membrane in bubble-like sacks that are made from pieces of the membrane. Q: How many different ways can molecules pass through a phospholipid membrane? Choices: - six - five - four - three A:
A: three
Question: Answer the following question given this paragraph: A given habitat may contain many different species, but each species must have a different niche. Two different species cannot occupy the same niche in the same place for very long. This is known as the competitive exclusion principle . If two species were to occupy the same niche, what do you think would happen? They would compete with one another for the same food and other resources in the environment. Eventually, one species would be likely to outcompete and replace the other. Q: What explains why two different species cannot occupy the same niche in the same place for very long? Choices: - evolution - natural selection - survival exclusion princple - competive exclusion princple A:
Answer: competive exclusion princple

Answer the following question given this paragraph: The place where the axon of one neuron meets the dendrite of another is called a synapse . Synapses are also found between neurons and other types of cells, such as muscle cells. The axon of the sending neuron does not actually touch the dendrite of the receiving neuron. There is a tiny gap between them, the synaptic cleft ( Figure below ). Q: What is the place called where the axon of one neuron meets the dendrite of another? Choices: - uptake - neurotransmitter - apoptosis - synapse A:
**Answer**
synapse

Answer the following question given this paragraph: A transverse wave can be characterized by the high and low points reached by particles of the medium as the wave passes through. This is illustrated in Figure below . The high points are called crests, and the low points are called troughs. Q: What are the high points of a transverse wave called? Choices: - peaks - troughs - ridges - crests A:
**Answer**
crests
