Frogs are amphibians and they undergo cutaneous respiration. Here the gaseous exchange occurs across the skin rather than gills or lungs. This... View Article
The process of digestion begins from the mouth or in the oral cavity, which later passes to the hollow tube-like organ the esophagus, then to the... View Article
The food, which is thoroughly mixed with the gastric juices in the stomach is moved further into the small intestine, where further digestion... View Article
Yes. Similar to humans and other living species, frogs do have a stomach and other specialized digestive organs, which are involved in digestion... View Article

Rotifers are multicellular animals, which undergo a sexual mode of reproduction. Rotifers are dioecious i.e. they comprise both male and female... View Article
Yes. Similar to humans and other animal species, rotifers have a digestive system, which comprises a mouth, ciliated buccal tube, pharynx,... View Article
Rotifers are called wheel animals because they are composed of several ciliated tufts around the mouth, which are involved in motion and resemble... View Article

Yes. Rotifers have a small brain with a simple nervous system. In rotifers, the brain is positioned exactly above the mastax, from which a number... View Article
Lactic acid fermentation occurs when oxygen is insufficient to carry out oxidative phosphorylation. Pyruvic acid is reduced to lactic acid and... View Article
No, alcohol fermentation does not require oxygen. It is an anaerobic process. Glucose is converted into ethanol and carbon dioxide by alcoholic... View Article
In fermentation, the first process is the same as aerobic respiration, which is the formation of pyruvic acid by glycolysis. Pyruvic acid can... View Article
No, alcohol fermentation is irreversible as CO2 produced at the end diffuses away. Lactic acid fermentation is reversible, when oxygen is... View Article
Alcoholic fermentation is a process by which sugar is converted into ethyl alcohol and CO2 by some bacteria and yeast. First, sugar is converted... View Article
Dehydrogenase is an oxidoreductase enzyme, which catalyses redox reactions. One substrate is oxidised and another gets reduced. E.g. pyruvate... View Article
Alcohol dehydrogenase catalyses the interconversion of alcohol to aldehyde or ketones with the reduction of NAD+ to NADH. In yeast and bacteria,... View Article
