Biology
1 answer:
Vikentia [17]3 years ago
5 0

Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. Viruses can infect animals, plants, and even other microorganisms.

Why might a scientist want to disrupt the plasma membrane and how might they do this experimentally?
kupik [55]

It is possible to disrupt the plasma membrane by using enzymes and/or detergent agents.

<h3>What is the plasma membrane?</h3>

The plasma membrane is a lipid bilayer that is mainly composed of phospholipids and cholesterol.

In laboratory conditions, it is possible to disrupt this lipid bilayer by using detergent and proteins (enzymes) that break the bonds binding phospholipids.

For example, enzymes can break down the double bonds that bind fatty acids in the lipid bilayer.

In conclusion, the plasma membrane can be break down by applying enzymes and detergents.

After performing a gram stain of a mixed culture of gram positive and gram negative cells, you shout: "oops, i forgot the iodine
zalisa [80]

Gram's staining is a differential staining technique that employs a primary stain like crystal violet and a counter stain like safranin along with the decolourizing agent alcohol and a mordant called the Gram's iodine.

Iodine is a mordant added after the primary stain. It fixes the stain by combining with it to enchance the staining ability. This forms an insoluble crystal violet iodine complex appearing purple under the microscope. These microorganisms are classified as Gram positive.

If addition of iodine is skipped, crystal violet is not fixed on the slide and the insoluble complex is not formed. The cells are decolourized by alcohol and are stained by the counter stain safranin making the Gram positive cells wrongly indentified as Gram negative due to its pink colouration. Thus, the slide will show all the cells as pink coloured Gram negative cells.
