Expain the process of nutrition takes place bud of hydra |
|
Answer» While feeding, Hydra extend their body to maximum length and then slowly extend their tentacles. DESPITE their SIMPLE construction, the tentacles of Hydra are extraordinarily extensible and can be four to five times the length of the body. Once FULLY extended, the tentacles are slowly manoeuvred around waiting for contact with a suitable prey animal. Upon contact, NEMATOCYSTS on the tentacle fire into the prey, and the tentacle itself coils around the prey. Within 30 seconds, most of the remaining tentacles will have already joined in the attack to subdue the struggling prey. Within two minutes, the tentacles will have surrounded the prey and moved it into the opened mouth aperture. Within ten minutes, the prey will have been engulfed within the body cavity, and digestion will have started. Hydra are able to stretch their body wall considerably in order to digest prey more than twice their size. After two or three days, the indigestible remains of the prey will be discharged through the mouth aperture VIA contractions. |

Explain the three ways in which glucose is broken down to get energy |
|
Answer» Answer:- break down of pyruvate takes place in different manners in different organisms. (i) Anaerobic respiration: This process takes place in absence of oxygen e.g., in YEAST during fermentation. In this case pyruvate is converted into ethanol and carbon dioxide. (ii) Aerobic respiration: In aerobic respiration break down of pyruvate takes place in PRESENCE of oxygen to give RISE 3 molecules of carbon dioxide and water. The release of energy in aerobic respiration is much more than anaerobic respiration. (iii) Lack of oxygen: Sometimes, when there is lack of oxygen, especially during vigorous activity, in our muscles, pyruvate is converted into LACTIC acid (3 carbon molecule compound). Formation of lactic acid in muscles causes cramp. |
