Ques:Q: What paired organs together receive about 25 percent of cardiac output and are protected in the retroperitoneal space by the renal fat pad and overlying ribs and muscle? Read this paragraph and choose the correct option from the provided answers: 25.3 Gross Anatomy of the Kidney As noted previously, the structure of the kidney is divided into two principle regionsthe peripheral rim of cortex and the central medulla. The two kidneys receive about 25 percent of cardiac output. They are protected in the retroperitoneal space by the renal fat pad and overlying ribs and muscle. Ureters, blood vessels, lymph vessels, and nerves enter and leave at the renal hilum. The renal arteries arise directly from the aorta, and the renal veins drain directly into the inferior vena cava. Kidney function is derived from the actions of about 1.3 million nephrons per kidney; these are the "functional units. " A capillary bed, the glomerulus, filters blood and the filtrate is captured by Bowman's capsule. A portal system is formed when the blood flows through a second capillary bed surrounding the proximal and distal convoluted tubules and the loop of Henle. Most water and solutes are recovered by this second capillary bed. This filtrate is processed and finally gathered by collecting ducts that drain into the minor calyces, which merge to form major calyces; the filtrate then proceeds to the renal pelvis and finally the ureters. Choices: - hands - lungs - brain - kidneys A:

Ans:kidneys

Ques:Q: Sugars are simple types of what biochemical compounds and possess relatively small molecules? Read this paragraph and choose the correct option from the provided answers: Carbohydrates are biochemical compounds that include sugar, starch, glycogen, and cellulose. Sugars are simple carbohydrates with relatively small molecules. Glucose is one of the smallest sugar molecules. Its chemical formula is C 6 H 12 O 6 . This means that a molecule of glucose contains 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen. Plants and some other organisms make glucose in the process of photosynthesis. Living things that cannot make glucose can obtain it by consuming plants or organisms that consume plants. Choices: - proteins - vegetables - lipids - carbohydrates A:

Ans:carbohydrates

Ques:Q: During which stage of development do all the major organs begin to form? Read this paragraph and choose the correct option from the provided answers: After cells differentiate, all the major organs begin to form during the remaining weeks of embryonic development. A few of the developments that occur in the embryo during weeks 4 through 8 are listed in Figure below . As the embryo develops, it also grows in size. By the eighth week of development, the embryo is about 30 millimeters (just over 1 inch) in length. It may also have begun to move. Choices: - third trimester - nascent - transgenic - embryonic A:

Ans:embryonic

Ques:Q: What is igneous rock created from? Read this paragraph and choose the correct option from the provided answers: Igneous rocks cool from magma. The appearance of the rock is created by the composition of the magma. It is also determined by the rate that the magma cools. If the magma cools deep underground, it cools slowly. If the magma cools at or very near the surface, it cools quickly. This results in two different rock types. The rock types can be told apart by the size of their crystals. The size of the crystals creates the texture of the rock. Choices: - magma aging - volcanic ash - carbon dioxide - magma cooling A:

Ans:
magma cooling
