6. What is produced when human cells respire aerobically?
7. How do plants take in air?
8. Where does gaseous exchange occur in fish? answer in one sentence
Answers
Answer:
6. Carbon dioxide is a byproduct of aerobic respiration in humans. Yes. When humans and other animals lack sufficient oxygen, they'll create ATP through a form of anaerobic respiration that produces lactic acid as a byproduct. Cells produce ATP through lactic acid fermentation only under when they lack sufficient oxygen.
7. Plants do breathe - they give out carbon dioxide and absorb oxygen from the air that surrounds them. Their tissues respire just as animal tissues do. ... The parts above the soil get their oxygen directly from the air through pores. The pores in the leaves are called stomata (singular: stoma).
8. Water taken in continuously through the mouth passes backward between the gill bars and over the gill filaments, where the exchange of gases takes place. The gills are protected by a gill cover in teleosts and many other fishes but by flaps of skin in sharks, rays, and some of the older fossil fish groups.
Answer:
CO2
by stomata
gills
