(B) Charle's lawAvogadro's lawEqual masses of methane and oxygen are mispressure exerted by oxygen isIIT -8111 273D) 3 298(C) 2/3 |
| Answer» <p>If x g of both oxygen and methane are mixed then : Mole of oxygen = x/32 Mole of methane = x/16 ⇒ mole fraction of oxygen = (x/32)/(x/32 + x/16) = 1/3 According to law of partial pressure Partial pressure of oxygen (po2) = mole-fraction × total pressure ⇒ 〖Po〗_2/p = 1/3</p><p>Option A is correct </p> | |

The experimental value of Poisson's ratio is between(A) 1 to -0.5(C) -1 to -0.5(B) 0.2 to 0.4(D) -1 to 0.5 |
| Answer» <p>(D) -1 to 0.5</p><p>Explanation:The Poisson's ratio of a stable, isotropic, linear elastic material cannot be less than −1.0 nor greater than 0.5 due to the requirement that Young's modulus, the shear modulus and bulk modulus have positive values. Most materials have Poisson's ratio values ranging between 0.0 and 0.5.</p> <p>thanks</p> | |

Explain the structure of heart with the help of a diagram and a flow chart. |
| Answer» <p>Parts of the Heart</p><p>As you can see in the above diagram, heart consists of various parts. So, as we discuss the various parts, you keep checking out the parts simultaneously in the above given labeled diagram of the human heart. This will help you to understand the functioning of its different parts.</p><p>PericardiumHuman heart is covered by a double layered structure which is known as pericardium. The outer layer is associated with the major blood vessels whereas the inner layer is attached to the cardiac muscles. These layers are separated by a pericardial fluid. This covering is like a membrane which holds all the parts of the heart.</p><p>ChambersHeart is divided into four chambers, left atrium, left ventricle, right atrium and right ventricle. Atriums are the upper chambers of the heart, whereas ventricles are the lower chambers of the heart. All these chambers are separated by a layer of tissues known as septum. Left side of the chamber is associated with the circulation of the oxygenated blood and the right side receives the deoxygenated blood from various parts of the body.</p><p>ValvesThere are four valves in the heart namely bicuspid valve, tricuspid valve, pulmonary valve and aortic valve. They help in preventing the back flow of the blood from one chamber to other. This maintains a proper one directional blood flow throughout the process. Bicuspid valve is present between the left atrium and left ventricle whereas tricuspid valve is present between the right atrium and right ventricle. Pulmonary valve behaves as a gate which stops the back flow of blood from right ventricle to the pulmonary artery which takes the deoxygenated blood to the lungs for purification. Lastly the aortic valve, this valve plays an important role in stopping the back flow of the blood from left ventricle to the aorta. Once the blood is transferred to the aorta it supplies the oxygenated blood to different parts of the body.</p><p>Blood VesselsBlood vessels are the blood carriers in a human body. These play a very vital role in the supply of blood to various parts of the body. Blood vessels can be of two types, veins and arteries. All the veins (except pulmonary vein) are involved in carrying the deoxygenated blood from various parts of the body to the heart whereas all the arteries (except pulmonary artery) are involved in supplying oxygenated blood from the heart to different parts of the body.</p> | |

Describe the physiology of urine formation. |
| Answer» <p>Glomerular Filtration</p><p>Glomerular filtration occurs as blood passes into the glomerulus producing a plasma-like filtrate (minus proteins) that gets captured by the Bowman’s (glomerular) capsule and funneled into the renal tubule. This filtrate produced then becomes highly modified along its route through the nephron by the following processes, finally producing urine at the end of the collecting duct.</p><p>Tubular Reabsorption</p><p>As the filtrate travels along the length of the nephron, the cells lining the tubule selectively, and often actively, take substances from the filtrate and move them out of the tubule into the blood. Recall that the glomerulus is simply a filter and anything suspended in the plasma that can fit through the holes in the filtration membrane can end up in the filtrate. This includes very physiologically important molecules such as water, sodium, chloride, and bicarbonate (along with many others) as well as molecules that the digestive system used a lot of energy to absorb, such as glucose and amino acids. These molecules would be lost in the urine if not reclaimed by the tubule cells. These cells are so efficient that they can reclaim all of the glucose and amino acids and up to 99% of the water and important ions lost due to glomerular filtration. The filtrate that is not reasbsorbed becomes urine at the base of the collecting duct.</p><p>Tubular Secretion</p><p>Tubular secretion occurs mostly in the PCT and DCT where unfiltered substances are moved from the peritubular capillary into the lumen of the tubule. Secretion usually removes substances from the blood that are too large to be filtered (ex: antibiotics, toxins) or those that are in excess in the blood (ex: H+, K+). These substances secreted into the tubule are destined to leave the body as components of urine.</p> | |
