Answer the following question given this paragraph: Accuracy is how close a measurement is to the true value. For example, 66 mL is a fairly accurate measurement of the liquid in Figure above . Q: What is the term for how close a measurement is to the true value? Choices: - frequency - validity - correctness - accuracy A:
accuracy
Answer the following question given this paragraph: A: Some animals can see light in the infrared or ultraviolet range of wavelengths. For example, mosquitoes can see infrared light, which is emitted by warm objects. By seeing infrared light, mosquitoes can tell where the warmest, blood-rich areas of the body are located. Q: What type of light can mosquitoes see? Choices: - trichina - neon - spicule - infared A:
infared
Q: Answer the following question given this paragraph: No doubt you've had a sore throat before, and you've probably eaten cheese or yogurt. If so, then you've encountered the fascinating world of prokaryotes. Prokaryotes are single-celled organisms that lack a nucleus. They also lack other membrane-bound organelles. Prokaryotes are tiny and sometimes bothersome, but they are the most numerous organisms on Earth. Without them, the world would be a very different place. Prokaryotes are the simplest organisms. The first cells and organisms to evolve would be classified as prokaryotic. Q: What group of single-celled organisms lacking a nucleus comprises the most numerous organisms on earth? Choices: - eukaryotes - carbohydrates - fungi - prokaryotes A:
A: prokaryotes
Question: Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. They contain a material such as silicon that absorbs light energy and gives off electrons. The electrons flow and create electric current. Figure below and the animation at the URL below show how a solar cell uses light energy to produce electric current and power a light bulb. Many calculators and other devices are also powered by solar cells. Q: What do solar cells convert the energy in sunlight into? Choices: - free energy - experimental energy - subsequent energy - electrical energy A:
Answer: electrical energy

Answer the following question given this paragraph: After a star becomes a red giant, it will take one of several different paths to end its life. Which path is followed by a star after the red giant phase depends on its mass. During the fusion life of a star, its size is the result of a competition between fusion heat pushing the material out and gravity pulling the material in. At the end, gravity always wins. After the star has lived through its red giant stage, the fusion essentially ends (the star runs out of fuel) allowing gravity to collapse the star. Some of the outer layers of material will be blown away and the core becomes smaller and denser. The core will become either a neutron star, a white dwarf, a black dwarf, or a black hole. Q: After what life stage does the fusion inside a star end? Choices: - blue giant - yellow dwarf - white dwarf - red giant A:
**Answer**
red giant

Answer the following question given this paragraph: The cell walls in many species of fungi contain chitin. Chitin is tough carbohydrate found in the shells of animals such as beetles and lobsters. The cell wall of a plant is made of cellulose, not chitin. Q: Chitin is a substance that is found in what part of animals like beetles and lobsters? Choices: - brains - tails - eggs - shell A:
(Answer)
shell
