Answer the following question given this paragraph: Earth's gravity also affects the acceleration of objects that start out moving horizontally, or parallel to the ground. Look at Figure below . A cannon shoots a cannon ball straight ahead, giving the ball horizontal motion. At the same time, gravity pulls the ball down toward the ground. Both forces acting together cause the ball to move in a curved path. This is called projectile motion . Q: Which factor causes a cannon ball to move horizontally and then fall on the ground? Choices: - cone motion - fluid motion - downward motion - projectile motion A:
projectile motion

Answer the following question given this paragraph: In physics, resistance is opposition to the flow of electric charges in an electric current as it travels through matter. The SI unit for resistance is the ohm. Resistance occurs because moving electrons in current bump into atoms of matter. Resistance reduces the amount of electrical energy that is transferred through matter. That's because some of the electrical energy is absorbed by the atoms and changed to other forms of energy, such as heat. You can see an animation of resistance at the level of atoms and electrons at this URL: http://www. physics. org/explorelink. asp?id=1738&q=electricalresistance&currentpage=1&age=0&knowledge=0&item=3. Q: In physics, resistance is opposition to the flow of what? Choices: - temperature charges - capacitance - surface flow - electrical charges A:
(Answer)
electrical charges
Ques: Answer the following question given this paragraph: Some bacteria depend on other organisms for survival. For example, some bacteria live in the roots of legumes, such as pea plants ( Figure below ). The bacteria turn nitrogen-containing molecules into nitrogen that the plant can use. Meanwhile, the root provides nutrients to the bacteria. In this relationship, both the bacteria and the plant benefit, so it is known as a mutualism . Q: In biology, a relationship that benefits both entities is known as what? Choices: - naturalism - altruism - predatory - mutualism A:
Ans: mutualism

Answer the following question given this paragraph: Nuclear energy is released when the nucleus of an atom is split. Q: What kind of energy is released when the nucleus of an atom is split? Choices: - microwave - kinetic - atomic - nuclear A:
(A).
nuclear
Ques:Answer the following question given this paragraph: Another example of species loss due to habitat destruction happened on Madagascar's central highland plateau. From 1970 to 2000, slash-and-burn agriculture destroyed about 10% of the country's total native plants. The area turned into a wasteland. Soil from erosion entered the waterways. Much of the river ecosystems of several large rivers were also destroyed. Several fish species are almost extinct. Also, some coral reef formations in the Indian Ocean are completely lost. Q: What kind of agriculture destroyed about 10% of madagascar's native plants? Choices: - hybridization - crop rotation - fertilizer use - slash-and-burn A:

Ans:slash-and-burn
Ques: Answer the following question given this paragraph: Cellular respiration takes place in the stages shown here. The process begins with a molecule of glucose, which has six carbon atoms. What happens to each of these atoms of carbon?. Q: What type of molecule is first broken down in cellular respiration? Choices: - oxygen molecule - hydrogen molecule - fructose molecule - glucose molecule A:
Ans:
glucose molecule
