Answer the following question given this paragraph: Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition. Most matter consists of mixtures of pure substances, which can behomogeneous (uniform in composition) or heterogeneous (different regions possess different compositions and properties). Pure substances can be either chemical compounds or elements. Compounds can be broken down into elements by chemical reactions, but elements cannot be separated into simpler substances by chemical means. The properties of substances can be classified as either physical or chemical. Scientists can observe physical properties without changing the composition of the substance, whereas chemical propertiesdescribe the tendency of a substance to undergo chemical changes (chemical reactions) that change its chemical composition. Physical properties can be intensive or extensive. Intensive properties are the same for all samples; do not depend on sample size; and include, for example, color, physical state, and melting and boiling points. Extensive properties depend on the amount of material and include mass and volume. The ratio of two extensive properties, mass and volume, is an important intensive property called density. Q: What term describes anything that occupies space and has mass, and is generally divided into three states? Choices: - stuff - lquid - galaxy - matter A:
(Answer)
matter
Ques: Answer the following question given this paragraph: Magnetism is due to the movement of electrons within atoms of matter. When electrons spin around the nucleus of an atom, it causes the atom to become a tiny magnet, with north and south poles and a magnetic field. In most materials, the electrons orbiting the nuclei of the atoms are arranged in such a way that the materials have no magnetic properties. Also, in most types of matter, the north and south poles of atoms point in all different directions, so overall the matter is not magnetic. Examples of nonmagnetic materials include wood, glass, plastic, paper, copper, and aluminum. These materials are not attracted to magnets and cannot become magnets. Q: Magnetism is due to the movement of what within atoms? Choices: - neutrons - protons - magnetrons - electrons A:
Ans: electrons

(A).
east to west
Ques:Answer the following question given this paragraph: Fossils are a window into the past. They provide clear evidence that evolution has occurred. Scientists who find and study fossils are called paleontologists . How do they use fossils to understand the past? Consider the example of the horse, shown in Figure below . The fossil record shows how the horse evolved. Q: Scientists who find and study fossils are called what? Choices: - biologists - geologists - anthropologist - paleontologists A:

Ans:paleontologists
Answer the following question given this paragraph: Runoff causes more erosion if the land is bare. Plants help hold the soil in place. The runoff water pictured below ( Figure below ) is brown because it eroded soil from a bare, sloping field. Can you find evidence of erosion by runoff where you live? What should you look for?. Q: On what type of land does runoff cause more erosion? Choices: - grassy - metallic - mountainous - bare A:
bare
