Answer the following question given this paragraph: Air movement takes place in the troposphere. This is the lowest layer of the atmosphere. Air moves because of differences in heating. These differences create convection currents and winds ( Figure below ). Q: What is the lowest layer of the atmosphere called? Choices: - mesosphere - lithosphere - asthenosphere - troposphere A:
troposphere

Answer the following question given this paragraph: Animals often have gonads , organs that produce eggs or sperm. The male gonads are the testes , and the female gonads are the ovaries . Testes produce sperm; ovaries produce eggs. Sperm and egg, the two sex cells, are known as gametes , and can combine two different ways, both of which combine the genetic material from the two parents. Gametes have half the amount of the genetic material of a regular body cell; they are haploid cells. In humans, gametes have one set of 23 chromosomes. Gametes are produced through a special type of cell division known as meiosis . Normal human cells have 46 chromosomes. They are diploid cells, with two sets of 23 chromosomes (23 pairs). Q: What are female gonads normally called? Choices: - testes - tubules - glands - ovaries A:
(Answer)
ovaries
Ques: Answer the following question given this paragraph: Innate Behaviors: Movement and Migration Innate or instinctual behaviors rely on response to stimuli. The simplest example of this is a reflex action, an involuntary and rapid response to stimulus. To test the "knee-jerk" reflex, a doctor taps the patellar tendon below the kneecap with a rubber hammer. The stimulation of the nerves there leads to the reflex of extending the leg at the knee. This is similar to the reaction of someone who touches a hot stove and instinctually pulls his or her hand away. Even humans, with our great capacity to learn, still exhibit a variety of innate behaviors. Q: The "knee-jerk" motion that people involuntarily perform after being struck in the knee in a certain way is an example of what kind of behavior? Choices: - reaction - spasm - sensor - reflex A:
Ans: reflex
(Q).
Answer the following question given this paragraph: The central tendency of a sample can be represented by the mean, median, or mode. Q: What part of a sample can be represented by the mean, median, and mode? Choices: - present tendency - large tendency - outer tendency - central tendency A:
(A).
central tendency
Ques:Answer the following question given this paragraph: Fusion is the process in which two atomic nuclei fuse together to make a single nucleus. Energy is released in the form of nuclear particles, neutrons, and gamma-rays. Q: What is the term for the process in which two atomic nuclei fuse together to make a single nucleus? Choices: - absorption - fission - binding - fusion A:

Ans:fusion
Ques: Answer the following question given this paragraph: 19.5 Capacitors and Dielectrics A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.13. (Most of the time an insulator is used between the two plates to provide separationsee the discussion on dielectrics below. ) When battery terminals are connected to an initially uncharged capacitor, equal amounts of positive and negative charge, +Q and Q , are separated into its two plates. The capacitor remains neutral overall, but we refer to it as storing a charge. Q: What do we call a device used to store electric charge? Choices: - charger - amplifier - battery - capacitor A:
Ans:
capacitor
