Answer:

In compare to eukaryotes,prokaryotes are morphologically simpler,more evolutionary primitive,less sensitive to physical environment.

Explanation:

Prokaryotes are unicellular organism which don't possess cell organelle like nucleus,mitochondria,Endoplasmic reticulum,golgi body, etc.

They are the first living organism in the primitive earth and the genetic components are located in the cytoplasm which is enclosed by cell membrane.

prokaryotes contain 3 domains that are Archaea, bacteria and eukarya.

The cytoplasm is enclosed by cell membrane.

Molecular studies have reveal that eukaryotes are evolved from prokaryotes.

Some prokaryotes bear long projection which helps them for locomotion,called as flagellum.This is present in gram positive and gram negative bacteria.

Staphylococcus epidermis appears _________, whereas escherichia coli appears _________ after the gram stain.
BigorU [14]

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.

Staphylococcus is a Gram-Positive Bacteria i.e. it takes up the Gram stain.

Escherichia coli or E. coli is a Gram-Negative Bacteria i.e. it does not take up the Gram stain.

Gram Staining is done by immersing the bacterial sample in a solution of dye and then observing it under microscope after proper rinsing.

Gram Positive Bacteria are those bacteria that show a positive outcome on staining. Gram Positive Bacteria appear Stained after staining.

Gram Negative Bacteria are those bacteria that show a negative outcome on staining. Gram Negative Bacteria does not take up the stain and appear stainless.

The epidermis of Staphylococcus which is a Gram-Positive Bacteria appears to take up the stain whereas Escherichia coli which is a Gram-Negative Bacteria does not take up the stain.

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.

using the process of bacterial transformtion, a student reseacher inserted a plasmid containing a gene for antibiotic resistance
Elena-2011 [213]

Transfer of newly created plasmids to e coli. The bacteria that contains a plasmid with antibiotic resistance will grow in the presence of antibiotic concludes that the insertion was successful.

<h3><u>Explanation:</u></h3>

The plasmid DNA that contains the foreign DNA when integrated with the competent bacteria which is e coli and heated,  plasmid DNA will be entering into the bacteria by means of some smaller pores that are created in the  membranes of the cell.

The plasmid DNA will be copied many times with the help of the replicating mechanism of DNA of the bacteria. Bacteria will grow on a nutrient rich food called agar after the transformation process. Those bacteria that contains a plasmid containing antibiotic resistance only grow in the antibiotic presence. Transformed bacteria will then grow in larger quantity.
