Ques:Answer the following question given this paragraph: A composite volcano forms the tall cone shape you usually think of when you think of a volcano. Shield volcanoes are huge, gently sloping volcanoes. Cinder cones are small, cone-shaped volcanoes. Q: What is the type of volcano with a tall cone shape that you picture when picturing a volcano? Choices: - advanced - active - inactive - composite A:

Ans:composite

Ques:Answer the following question given this paragraph: The name silicon dioxide implies one silicon atom and two oxygen atoms, so the formula is SiO2. We have a name that has numerical prefixes on both elements. Tri- means three, and tetrameans four, so the formula of this compound is Si3N4. Q: How many atoms of oxygen does silicon dioxide contain? Choices: - three - six - one - two A:

Ans:two

Ques:Answer the following question given this paragraph: The moment magnitude scale is the favored method of measuring earthquake magnitudes. It measures the total energy released by an earthquake. Moment magnitude is calculated by two things. One is the length of the fault break. The other is the distance the ground moves along the fault. Q: What scale measures the total energy released by an earthquake? Choices: - moment radiation scale - direct magnitude scale - moment identification scale - moment magnitude scale A:

Ans:moment magnitude scale

Ques:Answer the following question given this paragraph: 25.10 The Urinary System and Homeostasis The effects of failure of parts of the urinary system may range from inconvenient (incontinence) to fatal (loss of filtration and many others). The kidneys catalyze the final reaction in the synthesis of active vitamin D that in turn helps regulate Ca++. The kidney hormone EPO stimulates erythrocyte development and promotes adequate O2 transport. The kidneys help regulate blood pressure through Na+ and water retention and loss. The kidneys work with the adrenal cortex, lungs, and liver in the reninangiotensinaldosterone system to regulate blood pressure. They regulate osmolarity of the blood by regulating both solutes and water. Three electrolytes are more closely regulated than others: Na+, Ca++, and K+. The kidneys share pH regulation with the lungs and plasma buffers, so that proteins can preserve their three-dimensional conformation and thus their function. Q: What paired organs help regulate blood pressure through sodium ion and water retention and loss? Choices: - lungs - tissues - lymph nodes - kidneys A:

Ans:
kidneys
