7. How do plants take in air?
8. Where does gaseous exchange occur in fish?
Answers
Answer:
- Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to bring in oxygen and flush out carbon dioxide.
- The respiratory rate is defined as the number of breaths a person takes during a one-minute period of time while at rest. The normal ranges are for people at rest. Respiratory rates normally increase during exercise.
- Tiny hairs called cilia (pronounced: SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air
- Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen)
Answer:
1) The process of taking air into and expelling it from the lungs.
2) the respiratory rate is the rate in which the breathing occurs this is usually measured in breaths per minute and is set and controlled by the respiratory centre.
3) tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract filtering out dust and other particles that enter the nose through the breathed air.
4) the respiration without oxygen called cellular respiration.
5) In order to respire bacteria and fungi need food.
6) carbon dioxide is a byproduct of aerobic respiration.
7)plants do breathe they give out carbon dioxide and absorb oxygen from the air that surrounds them.
8)water taken in continuously through the mouth passes backward between the Gill bars and over the Gill filaments, where the exchange of gasses takes place.
