Answer the following question given this paragraph: Behind every fart is an army of gut bacteria undergoing some crazy biochemistry. These bacteria break down the remains of digested food through fermentation, creating gas in the process. Learn what these bacteria have in common with beer brewing at http://youtu. be/R1kxajH629A?list=PLzMhsCgGKd1hoofiKuifwy6qRXZs7NG6a . Q: Which process helps bacteria in the gut break down the remains of the digested food? Choices: - synthesis - decomposition - oxidation - fermentation A:
fermentation

Answer the following question given this paragraph: Objects that are launched into the air are called projectiles . The path followed by a projectile in motion is called a trajectory . The image of the snowboarder in the chapter introduction showed his trajectory; every object has a trajectory even when we cannot see it. Projectile motion , or the object's trajectory, is described in terms of position, velocity, and acceleration. Even with only an object's current location, velocity, and acceleration, we can calculate when and where the object will land. Our knowledge that perpendicular components of vectors do not affect each other allow us to easily analyze the motion of projectiles. Q: What are objects that are launched into the air called? Choices: - booms - stones - shoots - projectiles A:
(Answer)
projectiles
Ques: Answer the following question given this paragraph: Bacteria lack many of the structures that eukaryotic cells contain. For example, they don't have a nucleus. They also lack membrane-bound organelles, such as mitochondria or chloroplasts. The DNA of a bacterial cell is also different from a eukaryotic cell. Bacterial DNA is contained in one circular chromosome, located in the cytoplasm. Eukaryotes have several linear chromosomes. Bacteria also have two additional unique features: a cell wall and flagella. Q: Bacterial dna is contained in one circular chromosome, located where? Choices: - neuron - mucus - cerebellum - cytoplasm A:
Ans: cytoplasm
(Q).
Answer the following question given this paragraph: A scuba diver, like the one in Figure below , releases air bubbles when he breathes under water. As he gets closer to the surface of the water, the air bubbles get bigger. Boyle's law explains why. The pressure of the water decreases as the diver gets closer to the surface. Because the bubbles are under less pressure, they increase in volume even though the amount of gas in the bubbles remains the same. Q: A diver's air bubbles increase in size as he approaches the surface because what decreases? Choices: - water direction - water weight - water energy - water pressure A:
(A).
water pressure
Ques:Answer the following question given this paragraph: With logistic growth, the population starts out growing slowly, and then the rate of growth increasesbut only to a point. The rate of growth tapers off as the population size approaches its carrying capacity. Carrying capacity is the largest population size that can be supported in an area without harming the environment. This type of growth characterizes many populations. Q: With logistic growth, how does population growth start out? Choices: - exponentially - rapidly - steadily - slowly A:

Ans:slowly
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
