Answer the following question given this paragraph: Proteins are nutrients made up of smaller molecules called amino acids. The digestive system breaks down proteins in food to amino acids, which are used for protein synthesis. Proteins synthesized from the amino acids in food serve many vital functions. They make up muscles, control body processes, fight infections, and carry substances in the blood. Q: What is the name of the smaller molecules that make up proteins? Choices: - fundamental acids - DNA acids - rna acids - amino acids A:
amino acids

Answer the following question given this paragraph: The depression that allows water to collect to form a lake may come about in a variety of ways. The Great Lakes, for example, are glacial lakes. A glacial lake forms when a glacier scrapes a large hole in the ground. When the glacier melts, the water fills the hole and forms a lake. Over time, water enters the lake from the sources mentioned above as well. Q: What forms when a glacier scrapes a large hole in the ground? Choices: - frozen lake - drift lake - melting lake - glacial lake A:
(Answer)
glacial lake
Ques: Answer the following question given this paragraph: Kidneys: The Main Osmoregulatory Organ The kidneys, illustrated in Figure 41.4, are a pair of bean-shaped structures that are located just below and posterior to the liver in the peritoneal cavity. The adrenal glands sit on top of each kidney and are also called the suprarenal glands. Kidneys filter blood and purify it. All the blood in the human body is filtered many times a day by the kidneys; these organs use up almost 25 percent of the oxygen absorbed through the lungs to perform this function. Oxygen allows the kidney cells to efficiently manufacture chemical energy in the form of ATP through aerobic respiration. The filtrate coming out of the kidneys is called urine. Q: The kidneys are a pair of bean-shaped structures that are located just below and posterior to the liver in this? Choices: - stomach cavity - cerebral cavity - mantle cavity - peritoneal cavity A:
Ans: peritoneal cavity
(Q).
Answer the following question given this paragraph: Spinal Cord Development While the brain is developing from the anterior neural tube, the spinal cord is developing from the posterior neural tube. However, its structure does not differ from the basic layout of the neural tube. It is a long, straight cord with a small, hollow space down the center. The neural tube is defined in terms of its anterior versus posterior portions, but it also has a dorsalventral dimension. As the neural tube separates from the rest of the ectoderm, the side closest to the surface is dorsal, and the deeper side is ventral. As the spinal cord develops, the cells making up the wall of the neural tube proliferate and differentiate into the neurons and glia of the spinal cord. The dorsal tissues will be associated with sensory functions, and the ventral tissues will be associated with motor functions. Q: The spinal cord develops, cells making up the wall of the neural tube proliferate and differentiate into what? Choices: - membrane and glia - muscles and glia - jelly and glia - neurons and glia A:
(A).
neurons and glia
Ques:Answer the following question given this paragraph: Geothermal energy uses heat from magma within the Earth to heat homes or produce steam that turns turbines. Q: What kind of energy used heat from magma within the earth to heat homes or produce steam that turns turbines? Choices: - thermal energy - robust energy - renewable energy - geothermal energy A:

Ans:geothermal energy
Answer the following question given this paragraph: Pangaea has been breaking apart since about 250 million years ago. Divergent plate boundaries formed within the continents to cause them to rift apart. The continents are still moving apart. The Pacific is shrinking as the Atlantic is growing. The Appalachians ( Figure below ) are now on a passive margin. The mighty mountains have weathered and eroded to what they are today. Q: How many millions of years ago did pangaea begin breaking apart? Choices: - 600 - 400 - 500 - 250 A:
250
