Explain the differences between eukaryotic and prokaryotic cells.

Andrei [34K]2 years ago

Explanation:

Comparing prokaryotes and eukaryotes

All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.

The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.

Hypertonic environment

<h3>How do salts and sugars preserve food?</h3>

Salts and sugars work to preserve foods by creating a hypertonic environment. Salt and sugar will remove the water from the bacteria or fungi and they will not be able to proliferate. Loss of water results in plasmolysis, or cytoplasmic shrinkage.

<h3>What is hypertonic solution and plasmolysis?</h3>

Compared to another solution, a hypertonic solution has a higher solute concentration.

Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction. The live protoplast violently separates from the cell wall as a result of the loss of turgor. The vacuole is primarily responsible for the plasmolytic process.

A client with suspected human immunodeficiency virus (HIV) has had two positive enzyme-linked immunosorbent assay (ELISA) tests.
victus00 [196]

Answer:

Western blot should be performed

Explanation:

Generally ELISA test is sensitive to elevated antibodies levels in the blood. Because HIV infection is characterise with increases in antibodies levels(HIV-antibodies levels)of the body, it is usually the first screening test for HIV,however it  is also sensitive to elevated antibody   from  any other infection apart from HIV. Therefore for confirmation, the procedure is to run a second ELISA test, to determine if the antibody rise was due to HIV or not. If the second test turns positive, then Western blot can be applied.

The Western blot through  secondary and primary antibodies binding , separates the  investigating antibodies, and  identity the specif HIV antibodies present  to give a positive HIV-antibody,  confirming ELISA positive test.

Thus for confirmation of HIV specific antibodies  of the blood; ELISA test followed by Western blot is  ideal
