Answer the following question given this paragraph: Metal exposed to the outside elements will usually corrode if not protected. The corrosion process is a series of redox reactions involving the metal of the sculpture. In some situations, the metals are deliberately left unprotected so that the surface will undergo changes that may enhance the esthetic value of the work. Q: What process typically occurs to metal exposed to outside elements? Choices: - shrinkage - extraction - explosion - corrosion A:
(Answer)
corrosion
Ques: Answer the following question given this paragraph: The marsupial embryo is nourished inside the uterus with food from a yolk sac instead of through a placenta. The yolk sac stores enough food for the short period of time the embryo remains in the uterus. After the embryo is born, it moves into the mother's pouch, where it clings to a nipple. It remains inside the pouch for several months while it continues to grow and develop. Even after the offspring is big enough to leave the pouch, it may often return to the pouch for warmth and nourishment ( Figure below ). Eventually, the offspring is mature enough to remain outside the pouch on its own. Q: A yolk sac replaces what structure for nourishing a marsupial embryo? Choices: - uterus - glucose - Stomach - placenta A:
Ans: placenta
(Q).
Answer the following question given this paragraph: During metamorphism a rock may change chemically. Ions move and new minerals form. The new minerals are more stable in the new environment. Extreme pressure may lead to physical changes like foliation . Foliation forms as the rocks are squeezed. If pressure is exerted from one direction, the rock forms layers. This is foliation. If pressure is exerted from all directions, the rock usually does not show foliation. Q: Foliation, which forms layers in rocks during metamorphism, is caused by what? Choices: - Pulling - power - push - pressure A:
(A).
pressure

Choices: - melting point - transformation point - vapor point - boiling point A:
Answer:
