Imagine there was a campaign to wipe out all bacteria. Why would this not be a good
Sladkaya [172]

Answer:

If all the bacteria are removed from the earth, all the organisms are negatively affected.

Explanation: There are also some beneficial bacteria which helps in the nitrogen fixation called Nitrogen fixing bacteria such as Cyanobacteria and Azotobactor. These bacteria fixes atmospheric nitrogen into ammonium and nitrates form because plants are unable to use the atmospheric nitrogen, it only use nitrogen in ammonia and nitrates form. Plants absorb nitrates and form amino acid.

Why is it difficult to observe individual chromosomes with a light microscope during interphase?
asambeis [7]

Answer:

They have uncoiled to form long, thin strands.

Explanation:

Chromosomes are present in cell nucleus and consist of chromatin. Genes are present in linear order on chromosomes.  The chromosomes become visible under the microscope as distinct structures during cell division. When cells are not dividing, the chromosomes decondense to loose their individuality and make the mass of chromatin.  

Chromatin is complex of DNA and packing proteins. As the cells enter the prophase stage of cell division, condensation of chromatin occurs and individual chromosomes become visible under microscope. Before that (during interphase), chromosomes are not visible as they are present in decondensed form.

Explain the importance of essential oil metabolism in animals.
Volgvan
Plant essential oils (EOs) and their compounds have proven in vitro efficacy as antimicrobial, antioxidant, immunodulating and anti-inflammatory agents. These substances deserve an important place as feed additives that are generally considered as safe. The available in vivo data show that EOs could find use as natural growth promoters in animal diets. However, the available evidence on the possible positive effects of these substances on nutrient digestibility and the function of the gut is rather limited. Also, the benefits of EOs’ applications in animal’s diets depend on diverse parameters. These parameters can be, on the one hand, the unstable composition and the different levels of addition in the diet, and on the other hand, variable animal genetic factors. A better understanding of the gastrointestinal tract microflora composition and activity is needed in order to maximize the use of EOs and to manufacture effective products. Essential oils could find application in cases where approved drugs or chemical substances are unwanted, for example, biological farming. Hope this helps! Mark brainly please!
