Sound travel fast in cold air or hot air |
|
Answer» Sound travel faster in hot air because kinetic energy in hot air is high Sound travel fast in cold air bcoz molecules give space to sound to travel The speed of sound is greater in hot air than it is in cold air. This is because the molecules of air are moving faster and the vibrations of the sound wave can therefore be transmitted faster. |

Explain the process of formation of urine in humans |
| Answer» Urine is formed in the nephron of kidneys. Nephron is the structural and functional unit of the kidney. Blood at high pressure travels into these tubules by the tuft of blood capillaries called glomerulus contained in Bowman\'s capsule.The following steps are involved in the process:\t\xa0Filtration: Blood enters the glomerulus through the afferent arterioles It passes under high pressure that results in the filtration of blood. Water and small molecules are forced out of glomerular capillary walls and Bowman’s capsule. Large molecules remain in the blood of the glomerulus.\tSelective reabsorption: Some molecules are selectively reabsorbed into the blood. The glomerular filtrate flows through the proximal convoluted tubule, the U-shaped Henle’s loop and distal convoluted tubule. The useful substances such as glucose, amino acids and salts which require energy are reabsorbed by a process called selective reabsorption. Hence, the filtrate now contains urea, some salts and water. Reabsorption of solutes increases the water concentration of the filtrate. Water is then reabsorbed into the blood by osmosis.\tTubular secretion: Some nitrogenous waste products like creatinine and some other substances like K+ are removed from the blood by DCT (Distal Convoluted Tubule) and are passed to blood. The urine thus formed is collected in the urinary bladder. | |

Advantages and disadvantages of corrosion |
| Answer» Corrosion is a degradation process applicable mostly for metals. Just like we call rust for Iron. Unlike plastics, corrosion helps disposed metals to get back into the bio-cycle.Advantages:i. Protection : Surface corrosion forms an oxide layer which further protects the inner metal form corrosion.ii. Corrosion prevents corrosion: Some metals like zinc are used as sacrificial anodes to prevent corrosion to other metal.iii. Galvanic corrosion: The principle on which primary batteries work. In which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte.Disadvantages Of Corrosion:1. Weakens material due to prolonged corrosive action.2. Loss, contamination, and deterioration of the appearance of a material.3. Safety, health and environmental risks due to corrosion, especially in manufacturing plants.4. Corrosion tends to vent in technical malfunctions in machines. | |

Define reflex action. State its significance. How do plants respond to external stimuli |
| Answer» Reflex action : It is defined as an unconscious, automatic and involuntary response of effectors, i.e. muscles and glands, to a stimulus, which is monitored through the spinal cord.\xa0Significance : The deep tendon reflexes provide information on the integrity of the central and peripheral nervous system. Generally, decreased reflexes indicate a peripheral problem, and lively or exaggerated reflexes a central one.\xa0Plants produce hormones and respond to external stimuli, growing towards sources of water and light, which they need to survive. A tropism is a growth in response to a stimulus and an auxin is a plant hormone produced in the stem tips and roots, which controls the direction of growth.\xa0 | |
