Why is poultry farming done? State the names of species for it and how new species are developed. |
|
Answer» (/ˈpoʊltri/) are domesticated birdskept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails, and turkeys).Poultry also includes other birds that are killed for their meat, such as the young of pigeons(known as SQUABS) but does not include similar wild birds hunted for sport or food and known as game. The word "poultry" comes from the French/Norman word poule, itself derived from the Latin word pullus, which means small animal.The domestication of poultry took place several thousand years ago. This may have originally been as a result of people hatching and rearing young birds from eggs collected from the wild, but later involved keeping the birds PERMANENTLY in captivity. Domesticated chickens may have been used for cockfightingat first and quail kept for their songs, but soon it was realised how useful it was having a captive-bred source of food.Selective breeding for fast growth, egg-laying ability, conformation, plumage and docility took place over the CENTURIES, and modern breeds often look very different from their wild ancestors. Although some birds are still kept in small flocks in extensive systems, most birds available in the market today are reared in intensive commercial enterprises.Together with pig meat, poultry is one of the two most widely eaten types of meat globally, with over 70% of the meat supply in 2012 between them;[1] poultry provides nutritionally BENEFICIAL food containing high-quality protein accompanied by a LOW proportion of fat. All poultry meat should be properly handled and sufficiently cooked in order to reduce the risk of food poisoning. |

Explain briefly the breathing cycle in the human being |
|
Answer» mary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe. The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled. In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs. Once in the lungs, oxygen is moved into the bloodstream. Blood CARRIES the oxygen through the body to where it is needed. Red blood cells collect carbon dioxide from the body’s cells and transports it BACK to the lungs. An exchange of oxygen and carbon dioxide TAKES place in the alveoli, small structures within the lungs. The carbon dioxide, a waste gas, is exhaled and the cycle begins again with the next breath. The DIAPHRAGM is a dome-shaped muscle below the lungs that controls breathing. The diaphragm flattens out and pulls FORWARD, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs. Adults normally take 12 to 20 breaths per minute. Strenuous exercise drives the breath rate up to an average of 45 breaths per minute. |

A student designs an experiment to test substances X, Y, and Z, to determine which one is a catalyst for the reaction: A + B ® C. Only one of the unknown substances is a catalyst, and the others are nonreactive with A, B, or C. When 10 mL of A is added to 10 mL of B, the reaction takes twenty seconds. Bubbles form when the product C is created. The student prepares three test tubes, each containing both reactants A and B. She adds unknowns X, Y, and Z to test tubes 1, 2, and 3, respectively. She then times the reaction in each test tube from the point when the unknown is added until bubbling stops. How can the student identify the catalyst? The test tube that stops bubbling first contains the catalyst. The test tube that produces the most bubbles contains the catalyst. The test tube that bubbles the longest contains the catalyst. The test tube that does not bubble contains the catalys |

Answer» nt designs an experiment to test substances X, Y, and Z, to determine which one is a catalyst for the reaction: A + B ® C. Only one of the unknown substances is a catalyst, and the others are nonreactive with A, B, or C. When 10 mL of A is added to 10 mL of B, the reaction takes twenty SECONDS. Bubbles form when the product C is created. The STUDENT prepares three test tubes, each containing both REACTANTS A and B. She adds unknowns X, Y, and Z to test tubes 1, 2, and 3, RESPECTIVELY. She then times the reaction in each test tube from the point when the unknown is added until bubbling stops. How can the student identify the catalyst? Answer: The test tube contains the catalyst. The test tube that bubbles out contains the catalystReason for the answer: The reaction would proceed only in the presence of the catalyst. So from the test tube where the bubbles came out contains the Catalyst. |
