Question

Anaerobic respiration is seen in
1) Wasp
2) hydra
3) Cray fish
4)tapeworm ​

Answer 1

Answer:

4.Tapeworm

Explanation:

• Tapeworm respire in absence of water and produce lactic acid, ethanol, and a very less amount of energy. 
• Respiration in Hydra also occurs by diffusion through the epidermis surrounding the Hydra and carbon dioxide is also released in the same way. Hence hydra respire by aerobic mode of respiration.
• Wasps breathe discontinuously up to high temperatures despite a high resting metabolism.
• Crayfish, like all large crustaceans, use gills to gather oxygen. Found in the sides of the body and at the base of each leg.

Answer 2

Answer:

OPTION (4) Tapeworm

Explanation:

1. The anaerobic form of respiration leads to the incomplete breakdown of glucose into ethanol and $CO_{2}$ in some microorganisms, commonly observed in yeast.
2. A few species are found living in the intestines of human beings, for example, parasitic tapeworms.
3. Parasitic tapeworms rely on anaerobic respiration for their survival as it is not exposed to oxygen in the atmosphere.
4. Taenia solium is a facultative anaerobe.
5. It releases energy by decomposing glycogen into fatty acids.

Hence, anaerobic respiration is seen in tapeworms.
