Answer the following question given this paragraph: The stirrup in the middle ear passes the amplified sound waves to the inner ear through the oval window. When the oval window vibrates, it causes the cochlea to vibrate as well. The cochlea is a shell-like structure that is full of fluid and lined with nerve cells called hair cells. Each hair cell has many tiny "hairs," as you can see in the magnified image below . When the cochlea vibrates, it causes waves in the fluid inside. The waves bend the "hairs" on the hair cells, and this triggers electrical impulses. The electrical impulses travel to the brain through nerves. Only after the nerve impulses reach the brain do we hear the sound. Q: When the oval window vibrates, it causes what else to vibrate as well? Choices: - cilia - timpani - hammer and anvil - the cochlea A:
the cochlea

Answer the following question given this paragraph: There are other nerves in your body that are not found in the brain or spinal cord. The peripheral nervous system (PNS) ( Figure below ) contains all the nerves in the body that are found outside of the central nervous system. They include nerves of the hands, arms, feet, legs, and trunk. They also include nerves of the scalp, neck, and face. Nerves that send and receive messages to the internal organs are also part of the peripheral nervous system. Q: Nerves of the hands, arms, feet, legs, and trunk are part of what system? Choices: - urinary system - circulatory system - cardiovascular system - peripheral nervous system A:
(Answer)
peripheral nervous system
Ques: Answer the following question given this paragraph: The objects are at different temperatures, and heat flows from the hotter to the cooler object. This is always. Q: In which direction does heat always flow through objects? Choices: - from low to high - from cooler to hotter - from left to right - from hotter to cooler A:
Ans: from hotter to cooler
(Q).
Answer the following question given this paragraph: Band theory can explain virtually all the properties of metals. Metals conduct electricity, for example, because only a very small amount of energy is required to excite an electron from a filled level to an empty one, where it is free to migrate rapidly throughout the crystal in response to an applied electric field. Similarly, metals have high heat capacities (as you no doubt remember from the last time a doctor or a nurse placed a stethoscope on your skin) because the electrons in the valence band can absorb thermal energy by being excited to the low-lying empty energy levels. Finally, metals are lustrous because light of various wavelengths can be absorbed, causing the valence electrons to be excited into any of the empty energy levels above the highest occupied level. When the electrons decay back to low-lying empty levels, they emit light of different wavelengths. Because electrons can be excited from many different filled levels in a metallic solid and can then decay back to any of many empty levels, light of varying wavelengths is absorbed and reemitted, which results in the characteristic shiny appearance that we associate with metals. Q: What theory can explain virtually all the properties of metals? Choices: - property law theory - formation theory - bonding theory - band theory A:
(A).
band theory
Ques:Answer the following question given this paragraph: The marine west coast climate gets lots of rain from the nearby ocean. Q: The marine west coast climate gets lots of rain because of what being nearby? Choices: - the mountains - the Sun - highways - the ocean A:

Ans:the ocean
Ques: Answer the following question given this paragraph: The photos in Figure below show how farming practices can increase soil erosion. Plant roots penetrate the soil and keep it from eroding. Plowing turns over bare soil and cuts through plant roots. Bare soil is exposed to wind and water. In the past, farmers always plowed fields before planting. Some farmers now use no-till farming, which does not disturb the soil as much. Q: No-till farming is one effort to combat what, caused by typical farming practices? Choices: - habitat destruction - drought - pollution - soil erosion A:
Ans:
soil erosion
