Answer the following question given this paragraph: Ebola is a rare and deadly disease caused by infection with a strain of Ebola virus. The 2014 Ebola epidemic is the largest in history, affecting multiple countries in West Africa, including Guinea, Sierra Leone and Liberia. Ebola is spread through direct contact with blood and body fluids of a person infected by and already showing symptoms of Ebola. Ebola is not spread through the air, water, food, or mosquitoes. See Ebola virus disease at http://www. who. int/mediacentre/factsheets/fs103/en/ for additional information. Q: Ebola is an example of a disease spread by what kind of infectious agent? Choices: - bacteria - colds - flus - virus A:
virus

Answer the following question given this paragraph: Some samples of matter appear to have properties of solids, liquids, and/or gases at the same time. This can occur when the sample is composed of many small pieces. For example, we can pour sand as if it were a liquid because it is composed of many small grains of solid sand. Matter can also have properties of more than one state when it is a mixture, such as with clouds. Clouds appear to behave somewhat like gases, but they are actually mixtures of air (gas) and tiny particles of water (liquid or solid). The mass of an object is a measure of the amount of matter in it. One way to measure an object's mass is to measure the force it takes to accelerate the object. It takes much more force to accelerate a car than a bicycle because the car has much more mass. A more common way to determine the mass of an object is to use a balance to compare its mass with a standard mass. Although weight is related to mass, it is not the same thing. Weight refers to the force that gravity exerts on an object. This force is directly proportional to the mass of the object. The weight of an object changes as the force of gravity changes, but its mass does not. An astronaut's mass does not change just because she goes to the moon. But her weight on the moon is only one-sixth her earth-bound weight because the moon's gravity is only one-sixth that of the earth's. She may feel "weightless" during her trip when she experiences negligible external forces (gravitational or any other), although she is, of course, never "massless. " The law of conservation of matter summarizes many scientific observations about matter: It states that there is no detectable change in the total quantity of matter present when matter converts from one type to another (a chemical change) or changes among solid, liquid, or gaseous states (a physical change). Brewing beer and the operation of batteries provide examples of the conservation of matter (Figure 1.8). During the brewing of beer, the ingredients (water, yeast, grains, malt, hops, and sugar) are... Q: Some samples of matter appear to have properties of solids, liquids, and/or gases at the same time. this can occur when the sample is composed of many what? Choices: - turn pieces - large pieces - few pieces - small pieces A:
(Answer)
small pieces

Disaccharides contain two monosaccharide units, and polysaccharides contain many monosaccharide units. Q: A monosaccharide is the simplest carbohydrate and cannot be hydrolyzed to produce a smaller what? Choices: - amino acid - glucose atom - quark - carbohydrate molecule A:

Answer the following question given this paragraph: Classification of Joints on the Basis of Function The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses. A synarthrosis is a joint that is immovable. This includes sutures, gomphoses, and synchondroses. Amphiarthroses are joints that allow slight movement, including syndesmoses and symphyses. Diarthroses are joints that allow for free movement of the joint, as in synovial joints. Q: What category of joints is immovable? Choices: - amphiarthroses - sporozoans - diarthroses - synarthrosis A:
(A).
synarthrosis
Ques:Answer the following question given this paragraph: After Mendel's first set of experiments, Mendel wanted to see if the inheritance of characteristics were dependent, or were they independent events. Mendel asked if the segregation of the heritable factors (allele) for one characteristic (gene) had any effect of the segregation of the factors for another characteristic. For example, did the segregation of the flower color factors have any effect on the segregation of the seed shape factors? So Mendel performed crosses in which he followed the segregation of two genes. Mendel crossed pea plants that differed in two characteristics, such as seed color and shape. A dihybrid cross is a cross in which the inheritance of two characteristics are tracked at the same time. The offspring of such a cross are called dihybrids . Q: What is the term for a cross in which the inheritance of two characteristics are tracked at the same time? Choices: - fraternal - identical twin - Mendelian - dihybrid cross A:

Ans:dihybrid cross
Question: Answer the following question given this paragraph: Pressure is defined as the amount of force pushing against a given area. How much pressure a gas exerts depends on the amount of gas. The more gas particles there are, the greater the pressure. Q: What is the amount of force pushing against a given area? Choices: - inertia - power - energy - pressure A:
Answer:
pressure
