Answer the following question given this paragraph: Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles. All of these cell parts must be duplicated and then separated when the cell divides. A chromosome is a molecule of DNA, and will be the focus of a subsequent concept. Q: What important organelle (that would otherwise be centrally located and crucial to the cell's survival) do prokaryotic cells lack? Choices: - electrons - molecules - protons - nucleus A:
(Answer)
nucleus
Ques: Answer the following question given this paragraph: Two factors influence the pressure of fluids. They are the depth of the fluid and its density. Q: What two factors influence the pressure of fluids? Choices: - depth and gravity - time and temperature - temperature and density - depth and density A:
Ans: depth and density

Answer the following question given this paragraph: Gasoline and oils are complex chemical mixtures designed to burn in a way that will efficiently produce energy while emitting a minimal amount of air pollution. The refining of gasoline has improved engine performance but is much more complicated than simply using the crude products extracted from oil wells, as was common in the late 1800s. Most gasoline contained lead at one time, because this additive helped the engine run more smoothly. However, this caused lead contamination in the environment, so new "unleaded" formulations were created that could be burned smoothly without the addition of poisonous heavy metals. Oils for lubrication have special additives that reduce engine wear. Some special fuel blends have also been created to generate more power in race car engines. Q: Why did people stop adding lead to gasoline? Choices: - bad smell - to expensive - explosions - environmental pollution A:
(A).
environmental pollution
Ques:Answer the following question given this paragraph: Most protists consist of a single cell. Some are multicellular but they lack specialized cells. Q: Trash that gets into fresh and saltwater waterways is called what type of debris? Choices: - pollution - ocean - water - aquatic A:

Ans:aquatic
Ques: Answer the following question given this paragraph: Look at the wheelbarrow in the Figure below . It is used to carry heavy objects. It consists of two simple machines: a lever and a wheel and axle. Effort is applied to the lever by picking up the handles of the wheelbarrow. The lever, in turn, applies upward force to the load. The force is increased by the lever, making the load easier to lift. Effort is applied to the wheel of the wheelbarrow by pushing it over the ground. The rolling wheel turns the axle and increases the force, making it easier to push the load. Q: What simple machine works with a wheel and axle in a wheelbarrow? Choices: - pulley - hammer - blade - lever A:
Ans:
lever
