The _______________ community has low diversity with microorganisms primarily in the Leptospirillum groups II and III and from t
ExtremeBDS [4]

Answer:

The <u>Acidophilic Microbial</u> Community has low diversity with microorganisms primarily in Leptospirillum groups II and III and from Ferroplasma types I and II.

Explanation:

An acidophilic microorganism or plant is one which grows best in acidic conditions.

They are also referred to as microorganisms which occur in acidic natural (solfataric fields, sulphuric pools) and man-made (eg. Acid mine drainage) environments.

Acidophilic Microbes otherwise known as Acidophiles are an ecologically and economically important group.

They possess networked cellular adaptations for regulating intracellular pH. Several extracellular enzymes from acidophilic microbes are known to be functional at much lower pH than that inside the cells.

Acid stable enzymes have applications in several industries such as starch, baking, fruit juice processing, animal feed and pharmaceuticals, and some of them have already been commercialized. Acidophiles are widely used in bio-leaching of metals from low grade ores

Recent studies show that acidophiles are currently being considered to be utilized in bio-conversion and bio-remediation, as well as in microbial fuel cells to generate electricity.

Acidophilic microbes of similar characteristics are classifed in groups for ease of study and identification.

Leptospirillum Group II and II as well as Ferroplasma types I and II are groups of acidophilic microorganisms within the Acidophillic Microbial community.

Cheers!

What means RNA and it shape in the biology
MaRussiya [10]

The Answer is ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.

RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds.

I hope this helps you:)
