(a) “The breathing cycle is rhythmic whereas exchange of gases is a continuous process”.Justify this statement.(b) What happens if conducting tubes of circulatory system develops a leak? State in brief, how could this be avoided? |
Answer» ANSWER :(a) The breathing cycle involves inhalation and exhalation of air due to alternate expansion and contraction of thoracic cavity. THUS it is a rhythmic process. But exchange of gasesis a CONTINUOUS process as it takes place between the blood and each and every cell, by diffusion. (b) The circulatory system will become INEFFICIENT if it develops a LEAK. This could be avoided by maintaining a normal blood pressure. |

State two differences between arteries and veins. |
Answer» ANSWER:Arteries: Arteries carry oxygenated BLOOD, AWAY from the heart except pulmonary artery. These are thick-walled, HIGHLY muscular except arteries of cranium and vertebral column. Valves are ABSENT. Blood in arteries moves with pressure. Veins: Veins carry deoxygenated blood, towards the heart except pulmonary veins. These arethin-walled. Valves are present which provide unidirectional flow of blood.Blood in veins moves under very low pressure. |

What is an alloy? State the constituents of solder. Which property of solder makes itsuitable for welding electrical wires? |
|
Answer» Answer: What is an Alloy? An alloy is a combination of metals and of a metal or another element. Alloys are defined by a metallic bonding CHARACTER. An alloy may be a solid solution of metal elements or a mixture of metallic phases. Intermetallic compounds are alloys with a defined stoichiometry and crystal structure. The constituents of solder: The constituents which make up solder alloy are lead and tin. It has a low MELTING point but has excellent electrical conductivity, so it is used for soldering of electrical wires. Property of solder makes it suitable for welding electrical wires: Solder is an alloy of lead and tin. It is used for welding electric wires because of its low melting point. Solder is an alloy of lead and tin ( Pb and Sn ) and has low melting point. Therefore it is used for welding electrical wires together. ================================================== Hope My Answer Helps You! Please MARK me as BRAINLIEST and follow me also!!
