Answer the following question given this paragraph: The fovea is the region in the center back of the eye that is responsible for acute vision. The fovea has a high density of cones. When you bring your gaze to an object to examine it intently in bright light, the eyes orient so that the object's image falls on the fovea. However, when looking at a star in the night sky or other object in dim light, the object can be better viewed by the peripheral vision because it is the rods at the edges of the retina, rather than the cones at the center, that operate better in low light. In humans, cones far outnumber rods in the fovea. Q: What is the region in the center back of the eye that is responsible for acute vision? Choices: - cornea - lens - pupil - fovea A:
fovea
Answer the following question given this paragraph: Jupiter has lots of moons. As of 2012, we have discovered over 66 natural satellites of Jupiter. Four are big enough and bright enough to be seen from Earth using a pair of binoculars. These four moons were first discovered by Galileo in 1610. They are called the Galilean moons . The figure below shows the four Galilean moons and their sizes relative to each other ( Figure below ). These moons are named Io, Europa, Ganymede, and Callisto. The Galilean moons are larger than even the biggest dwarf planets, Pluto and Eris. Ganymede is the biggest moon in the solar system. It is even larger than the planet Mercury!. Q: The four moons of jupiter are collectively named after what 17th century astronomer, who discovered them? Choices: - Linnaeus - copernicus - darwin - galileo A:
galileo
Q: Answer the following question given this paragraph: Did you know that blood is a tissue? Blood is a fluid connective tissue that is made up of red blood cells, white blood cells, platelets, and plasma. The cells that make up blood are pictured below ( Figure below ). The different parts of blood have different roles. Q: Blood is made up of red blood cells, white blood cells, platelets, and what else? Choices: - pathogens - hemoglobin - potassium - plasma A:
A: plasma
Question: Answer the following question given this paragraph: Most aquatic organisms do not have to deal with extremes of temperature or moisture. Instead, their main limiting factors are the availability of sunlight and the concentration of dissolved oxygen and nutrients in the water. Q: Besides the concentration of dissolve oxygen and nutrients in the water, what other factor limits aquatic organisms? Choices: - rainfall - temperature - lake size - availability of sunlight A:
Answer: availability of sunlight

Answer the following question given this paragraph: When an atomic nucleus decays, it does so by releasing one or more particles. The atom often (but not always) turns into a different element during the decay process. The amount of radiation given off by a certain sample of radioactive material depends on the amount of material, how quickly it decays, and the nature of the decay product. Big, rapidly decaying samples are most dangerous. Q: The atom often (but not always) turns into a different what during the decay process? Choices: - concept - reaction - aspect - element A:
**Answer**
element

Answer the following question given this paragraph: Today, evolution is still questioned by some people. Often, people who disagree with the theory of evolution do not really understand it. For example, some people think that the theory of evolution explains how life on Earth first began. In fact, the theory explains only how life changed after it first appeared. Some people think the theory of evolution means that humans evolved from modern apes. In fact, the theory suggests humans and modern apes have a common ancestor that lived several million years ago. These and other misconceptions about evolution contribute to the controversy that still surrounds this fundamental principle of biology. Q: Misconceptions about what theory contribute to the controversy that still surrounds this fundamental principle of biology? Choices: - darwin on evolution - brain of evolution - cycle of evolution - theory of evolution A:
**Answer**
theory of evolution
