Answer the following question given this paragraph: The placenta permits a long period of fetal growth. As a result, the fetus can become relatively large and mature before birth. This increases its chances of survival. On the other hand, supporting a growing fetus may be difficult for the mother. She has to eat more while pregnant and may become less mobile as the fetus grows larger. Giving birth to a large infant is also risky. Q: The fetus becoming relatively large and mature before birth increases the chances of what? Choices: - disease - mutations - intelligence - survival A:
survival

Answer the following question given this paragraph: Q: Where can neurohormones act within the body? Choices: - nerve endings - digestive process - brain only - throughout A:
(Answer)
throughout
Ques: Answer the following question given this paragraph: Magnetic poles always occur in pairs of north and southit is not possible to isolate north and south poles. All magnetism is created by electric current. Ferromagnetic materials, such as iron, are those that exhibit strong magnetic effects. The atoms in ferromagnetic materials act like small magnets (due to currents within the atoms) and can be aligned, usually in millimeter-sized regions called domains. Domains can grow and align on a larger scale, producing permanent magnets. Such a material is magnetized, or induced to be magnetic. Above a material's Curie temperature, thermal agitation destroys the alignment of atoms, and ferromagnetism disappears. Electromagnets employ electric currents to make magnetic fields, often aided by induced fields in ferromagnetic materials. Q: Materials, such as iron, that exhibit strong magnetic effects are labeled what? Choices: - paramagnetic - superconducting - ultramagnetic - ferromagnetic A:
Ans: ferromagnetic
(Q).
Answer the following question given this paragraph: Cumulus clouds are white and puffy. Convection currents make them grow upward and they may grow very tall. When they produce rain, they are called cumulonimbus. Q: What causes cumulus clouds to grow upward? Choices: - moisture currents - gas currents - mantle currents - convection currents A:
(A).
convection currents
Ques:Answer the following question given this paragraph: Friction is the force that resists motion. In most beginning physics classes, friction is ignored. Concepts can be understood and calculations made assuming friction to be nonexistent. Whenever physics intersects with the real world, however, friction must be taken into account. Friction exists between two touching surfaces because even the smoothest looking surface is quite rough on a microscopic scale. Q: What type of force exists between two touching surfaces? Choices: - opposing - centrifugal - tension - friction A:

Ans:friction
Answer the following question given this paragraph: Q: What do some animals use to get a feel for their environment? Choices: - neuroreceptors - nociceptors - fibroblasts - mechanoreceptors A:
mechanoreceptors
