3 different type of blood cell and their function |
|
Answer» od is made up of three main component CELLS:Red Blood Cells Red blood cells, called erythrocytes, comprise about 40 to 50 percent of the overall blood volume. Levels vary for males and females, with men having 5 to 6 million erythrocytes per cubic millimeter of entire blood and women having 4 to 5 million per cubic millimeter. Red blood cells live for approximately 120 days prior to being changed by new cells produced in the bone marrow. The red color originates from a pigmented particle, called hemoglobin, inside red blood cells. Red blood cells carry oxygen throughout the body and provide carbon dioxide from tissues to the lungs to be exhaled.White Blood CellsWhite blood cells, also called leukocytes, are much fewer in number than red blood cells. There are 5 different types of white blood cells that collaborate to protect the body by attacking foreign intruders, consisting of bacteria, viruses and tumors. The most typical type of white blood cells are called neutrophils. All types of white blood cells are produced in the bone marrow.PlateletsPlatelets, also called thrombocytes, are cell fragments instead of entire cells. They clump TOGETHER and form blood clots after an injury. Clots FUNCTION as plugs to stop bleeding and function as a base for new tissue growth and recovery in the injured area. Certain blood-thinning medications reduce the risk of abnormal blood clots by interfering with platelet function. |

An electric oven consumes 1 kW electric power when operated at 220 v write the capacity of the fuse suitable for ur device .give reason for ur answer |
|
Answer» 5 AStep by step explanation:It is given that:P = 1 KWV = 220 VIt is REQUIRED to know the capacity of the fuse; which is the current.P = I*V1000 = I*220Therefore, the current FLOWING in the device; I = 1000/220 = 4.54 A Therefore, the fuse MUST be higher than 4.54 A because the function of the fuse is to protect a system from SHORT circuit current or HIGH currents.Therefore, I would suggest the fuse capacity to be 5 A. |

The TOP of the tongue, also called the dorsum, is covered with papillae, tiny nodes that contain the taste buds and the serous glands.The serous glands secrete some of the fluid found in saliva, while the taste buds taste food through receptors that send information to the brain. Receptors are nerve endings that have a chemical reaction to the food that is being eaten. There are DIFFERENT REACTORS for different types of flavors, and there are AROUND 50 to 150 taste receptor cells inside each taste bud, according to Encyclopedia Britannica. |
