To explain: The way in which tobacco smoking problem can be solved.
Introduction: Smoking affects respiration as they damage alveoli when cigarette smoke is inhaled for prolonged time period. As a result, the alveoli are unable to take part in gas exchange. There are approximately 300 million alveoli that provide large surface area for performing gas exchange. So, if alveoli are damaged due to smoking, the surface area for gas exchange would be decreased, which would cause problems in the breathing process.
To explain: The way in which smoking problem in young people should be targeted.

- How can we save our planet? Give different ways we can save planet Earth.arrow_forwardQuestion 3 of 190 FINAL - Science The question based on the following passage. The science of producing and transmitting sound waves in materials has become widespread with many practical applications. Ultrasonics was first developed during World War II as a method of detecting enemy submarines. Today ultrasonics has many applications. When the waves used are of a low amplitude, ultrasonics can be used to map the ocean's depths, detect flaws in materials, locate cancers in the human body, and scan fetuses for deformities. Higher-amplitude waves are used in cleaning, manufacturing materials, and determining fatigue tests for metals. The destruction of bacteria and the use of tightly focused ultrasound as a surgical knife are biological applications of high-amplitude waves. According to the passage, what is a low amplitude ultrasonic scanning of the human body able to do? A. remove bacteria painlessly B. give a clear picture of interior body details C. remove cancerous materials without…arrow_forwardA&P Practice Question 66arrow_forward
