Answer:

Anaerobes

Explanation:

Those organisms who live and reproduce in the absence of oxygen are termed as anaerobes. Those anaerobes that can not manage the presence of oxygen and harmed by even small quantity of oxygen are called obligate anaerobe, for example, <em>Clostridium botulinum</em>.

Those organisms which have the ability to grow in the absence of oxygen but utilize oxygen when oxygen is present are called facultative anaerobes for example in human intestine <em>E.coli </em>and other bacteria of Enterobacteriaceae family are facultative anaerobe.

There is one other category that contains anaerobe and called aerotolerant organisms which grow in the absence of oxygen and are tolerant towards oxygen. Therefore the correct answer is anaerobes.

Answer:Transcriptional Regulation

Explanation:

Eukaryotic gene expression can be regulated during the time of transcription and RNA processing, which takes place in the nucleus of the cell and then during the time of protein translation in the cytoplasm.

Further regulation is being carried during the time of post transnational modification. The conservation of energy is very important because it saves the overall energy and space in the body.

Hence, the most important point for the regulation would be transcriptional regulation.

Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the glucose molecules in cellulose. how then do cow

Andrei [34K]

Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.

Cellulose- The stable formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide. The fibrils (bundles of microfibrils) and microfibrils (bundles of polysaccharide) made up of cellulose chains make up the plant cell wall.

Glucose- The primary form of sugar in the blood, glucose serves as the body's cells' principal source of energy. Glucose may be produced by the body from other chemicals or it can be obtained from the meals we eat. The circulation carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.
