How does fish breathe under water?
2. What happens when breathed air is passed through lime water?
3. What is inhalation?
4. What are the functions of hair and mucus inside the nose?
5. What is breathing?
6. What is cellular respiration and where does it take place?
7. Write the names of various organs found in our respiratory system.​

Answer 1

Answer:fish breathes with help of gills.

Lime water turn milky a inhaled air has co2.

Process of taking in gases (o2) in body is inhalation

Hair and mucus help to trap dust particle entering through inhaled air.

Inhaling of o2 and exhaling of co2 is breathing

Lungs nose trachea are various organs

Explanation:

Answer 2

$\huge\red{ANSWER:-}$

1. Through the Gills
2. When exhaled air is blown through Lime Water which is also known as calcium hydroxide, the carbon dioxide present in the exhaled air reacts with the Lime water and turns it into a milky solution, since the the CO2 reacts with Ca(OH)2 and forms CaCO or Calcium Carbonate, which is insoluble and white in colour
3. the action of inhaling or breathing in.
4. the hair and mucus prevents dust, durt and germs from getting into the lungs. to trap any dust and dirt. the nose hair is also referred to "cilia." also, mucus traps dust and durt.
5. the process of taking air into and expelling it from the lungs.
6. Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
7. The organs of the respiratory system include the lungs, pharynx, larynx, trachea, and bronchi.
