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:
kidneys

Answer the following question given this paragraph: In order to absorb oxygen from the water, fish use gills ( Figure below ). Gills take dissolved oxygen from water as the water flows over the surface of the gill. Q: What part of the body do fish use to absorb oxygen? Choices: - dorsal fin - tail fin - under belly - gills A:
(Answer)
gills
Ques: Answer the following question given this paragraph: Eleutherozoa are the echinoderms that can move. This group includes the starfish and most other echinoderms. Q: Like other bryophytes, moss plants spend most of their life cycle as what? Choices: - zygotes - copepods - protozoa - gametophytes A:
Ans: gametophytes
(Q).
Answer the following question given this paragraph: A volcano is a vent through which molten rock and gas escape from a magma chamber. Volcanoes differ in many features, such as height, shape, and slope steepness. Some volcanoes are tall cones, and others are just cracks in the ground ( Figure below ). As you might expect, the shape of a volcano is related to the composition of its magma. The three types of volcanoes are composite, shield, and cinder cones. Q: What are the 3 types of volcanoes? Choices: - composite , atop , cinder cones - composite, seismic, fault - crude , shield , cinder cones - composite, shield, cinder cones A:
(A).
composite, shield, cinder cones
Ques:Answer the following question given this paragraph: Creep is the very slow movement of rock and soil down a hillside. Creep occurs so slowly you can't see it happening. You can only see the effects of creep after years of movement ( Figure below ). The slowly moving ground causes trees, fence posts, and other structures on the surface to tilt downhill. Q: What is the apt term for the very slow movement of rock and soil down a hillside? Choices: - glide - landslide - drop - creep A:

Ans:creep
Question: Answer the following question given this paragraph: A lymphocyte is the type of white blood cell involved in an immune system response. You can see what a lymphocyte looks like, greatly magnified, in Figure below . Lymphocytes make up about one quarter of all white blood cells, but there are trillions of them in the human body. Usually, fewer than half of the body's lymphocytes are in the blood. The majority are in the lymph, lymph nodes, and lymph organs. Q: A lymphocyte is the type of which cell involved in an immune system response? Choices: - red blood cell - white immunity cell - white brain cell - white blood cell A:
Answer:
white blood cell
