Answer the following question given this paragraph: Earth gets its energy from the Sun. The Sun gives off photons of energy that travel in waves. All the wavelengths of the Sun's energy make up the electromagnetic (EM) spectrum. Q: Where does the earth gets its energy from? Choices: - decomposers - precipitation - heat - sun A:
sun

Answer the following question given this paragraph: You generally can't see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below. Q: What does the geiger counter detect? Choices: - vibration - convection - moisture - radiation A:
(Answer)
radiation
Ques: Answer the following question given this paragraph: Facts are true. Data, gathered correctly, is factual. Facts and data are not subject to opinion or bias. Q: Refraction happens when light bends from doing what in a new medium? Choices: - changing brightness - changing color - changing trajectory - changing speed A:
Ans: changing speed
(Q).
Answer the following question given this paragraph: Polar tundra climates occur near the poles. Tundra climates have permafrost. Permafrost is layer of ground below the surface that is always frozen, even in the summer. Only small plants, such as mosses, can grow in this climate. Q: What is the layer of ground below the surface that is always frozen, even in the summer? Choices: - tundra - bedrock - upper crust - permafrost A:
(A).
permafrost
Ques:Answer the following question given this paragraph: No physical object can travel faster than the speed of light in a vacuum. (Maximum speed is finite). Q: Genetic variation helps ensure that some organisms will survive if what happens? Choices: - they get eaten - there's an earthquake - they die - their environment changes A:

Ans:their environment changes
Ques:Answer the following question given this paragraph: Sympatric speciation occurs when groups from the same species stop mating because of something other than physical or geographic separation. The behavior of two groups that live in the same region is an example of such separation. The separation may be caused by different mating seasons, for example. Sympatric speciation is more difficult to identify. Q: What occurs when groups from the same species stop mating because of something other than physical or geographic separation? Choices: - extinction - complementary speciation - invasive speciation - sympatric speciation A:

Ans:
sympatric speciation
