Answer the following question given this paragraph: Like Earth, the Moon has a distinct crust, mantle, and core. The crust is composed of igneous rock. This rock is rich in the elements oxygen, silicon, magnesium, and aluminum. On the near side, the Moon's crust is about 60 kilometers thick. On the far side, the crust is about 100 kilometers thick. The mantle is made of rock like Earth's mantle. The Moon has a small metallic core, perhaps 600 to 800 kilometers in diameter. The composition of the core is probably mostly iron with some sulfur and nickel. We learned this both from the rock samples gathered by astronauts and from spacecraft sent to the Moon. Q: Like earth, the moon has a distinct crust, mantle, and what else? Choices: - temperature - polarity - atmosphere - core A:
core

Ques: Answer the following question given this paragraph: Hemophilia is a group of diseases in which blood does not clot normally. Factors in blood are involved in clotting. When you bleed, your body begins a coagulation cascade of reactions, involving special proteins known as coagulation factors, to stop that bleeding. When one or more of these clotting factors are missing, there is a higher chance of having dificulties stoping the bleeding. Hemophiliacs lacking the normal Factor VIII are said to have Hemophilia A (or Factor VIII deficiency), the most common form. Hemophilia is a genetic disease, passed down through family. It is linked to the X-chromosome, so it mostly affects males. F8 is the gene for the Factor VIII protein. Mutations in the F8 gene lead to the production of an abnormal version of coagulation factor VIII, or reduce the amount of the protein. The altered or missing protein cannot participate effectively in the blood clotting process. Q: What is the term for diseases in which blood does not clot normally? Choices: - arthritis - diabetes - lymphoma - hemophilia A:
Ans: hemophilia

Answer the following question given this paragraph: Cooling and crystallization. Deep within the Earth, temperatures can get hot enough to create magma. As magma cools, crystals grow, forming an igneous rock. The crystals grow larger if the magma cools slowly, as it does if it remains deep within the Earth. If the magma cools quickly, the crystals will be very small. When crystals form from magma it is called crystallization . Q: What is it called when crystals form from magma? Choices: - sedimentation - transpiration - vulcanism - crystallization A:
(A).
crystallization
