Answer the following question given this paragraph: All objects in the universe have an attraction to each other. This attraction is known as gravity ( Figure below ). The strength of the force of gravity depends on two things. One is the mass of the objects. The other is the distance between the objects. As an object's mass increases, the attraction increases. As the distance between the objects increases, the attraction decreases. Q: The attraction between all objects in the universe is known as ______. Choices: - variation - electricity - magnetism - gravity A:
gravity

Answer the following question given this paragraph: For the first 4 billion years of Earth history there is only a little evidence of life. Organisms were tiny and soft and did not fossilize well. But scientists use a variety of ways to figure out what this early life was like. Note that the period from Earth's origin to the beginning of the Phanerozoic is called the Precambrian. Q: What is the period from earth's origin to the beginning of the phanerozoic eon? Choices: - Paleolithic - Cenozoic - anatolian - precambrian A:
(Answer)
precambrian
Ques: Answer the following question given this paragraph: Q: All cells have voltages across their what? Choices: - display membranes - ribosomes - nuclei - plasma membranes A:
Ans: plasma membranes
(Q).
Answer the following question given this paragraph: Sunlight is turned into electricity at a solar power plant. These power plants use a large group of mirrors to focus sunlight on one place. This place is called a receiver ( Figure below ). At the receiver, a liquid such as oil or water is heated to a high temperature. The liquid transfers its heat by conduction . In conduction, energy moves between two objects that are in contact. The higher temperature object transfers heat to the lower temperature object. For example, when you heat a pot of water on a stove top, energy moves from the pot to its metal handle by conduction. At a solar power plant, the energy conducted by the heated liquid is used to make electricity. Q: When you heat a pot of water on a stove top, energy moves from the pot to its metal handle by what process? Choices: - induction - convection - thermal radiation - conduction A:
(A).
conduction
Ques:Answer the following question given this paragraph: Plate tectonic processes explain why we see many types of geological activity where we do. Stresses build up in some locations. These stresses may cause folding or faulting. Earthquakes strike along all three types of plate boundaries. The most damaging earthquakes are shallow focus. People in earthquake-prone regions must be aware of the potential damage from earthquakes. Seismologists have scales for measuring earthquake intensity and magnitude. Cities in earthquake zones must build safe structures. They also have guidelines for being safe in earthquakes. Earthquakes are often associated with volcanoes. Volcanoes erupt at all types of plate boundaries except transform. Volcanic eruptions can be quiet or explosive. Volcanoes have a variety of shapes. The shapes range from large shields, to classic peaks, to small cones. Supervolcano eruptions are rare but extremely deadly. Volcanic activity creates unique landforms. Hot springs and geysers result when water meets hot rock below ground. Some geological activity, both earthquakes and volcanic eruptions, is located away from plate boundaries. Q: What causes a lot of geological activity on the earth? Choices: - landslides - weather - natural selection - plate tectonics A:

Ans:plate tectonics
Question: Answer the following question given this paragraph: The peripheral nervous system (PNS) consists of all the nervous tissue that lies outside the central nervous system. It is shown in yellow in Figure below . It is connected to the central nervous system by nerves. A nerve is a cable-like bundle of axons. Some nerves are very long. The longest human nerve is the sciatic nerve. It runs from the spinal cord in the lower back down the left leg all the way to the toes of the left foot. Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. Q: Which nervous system consists of all the nervous tissue that lies outside the central nervous system? Choices: - auxiliary nervous system - significant nervous system - function nervous system - peripheral nervous system A:
Answer:
peripheral nervous system
