For a given antibiotic, is there a difference in susceptibility between the gram-positive and gram-negative bacteria due to the structure of their cell wall.

The cell wall of gram-positive bacteria consists of a single thick layer composed of peptidoglycans. On the other hand, the cell wall of gram-negative bacteria is made up of three layers.

The first layer is the outer membrane, the second layer is the peptidoglycan layer and the third layer is the inner membrane made of phospholipid bilayer.

The outer membrane of Gram-negative bacteria is the mainly responsible for resistance to a wide range of antibiotics including β-lactams and other antibiotics.

A G:T base pair in DNA suggests that _____
Elan Coil [88]

Answer:

(A) The T was originally a cytosine, which was deaminated to a T

Explanation:

Adenine and guanine are found in both DNA and RNA.

Cytosine is found in both DNA and RNA.

Thymine is normally found in DNA.

In a CpG site (5'—C—phosphate—G—3') , that is, Cytosine and Guanine separated by only one phosphate group; phosphate links any two nucleosides together in DNA.

In a G:T base pair in DNA, Adenine pair with Thymine and Guanine pair with Cytosine.

Here in the question, The G:T base pair in DNA suggests that the T was originally a cytosine, which was deaminated to a T.

How methylation of CpG sites followed by spontaneous deamination leads to a lack of CpG sites in methylated DNA.

A  Cytosine base followed immediately by a Guanine base (a CpG) is rare in vertebrate DNA because the Cytosine in such an arrangement tend to be methylated. This methylation helps to distinguish the newly synthesized DNA strand from the parent strand, which aids in the final stages of DNA proofreading after duplication. However, over time methylated cytosines tend to turn into Thymine because of spontaneous deamination.

Which of the following is an example of an eukaryotic organism?
solong [7]

Just about every living organism on Earth can be placed in one of two classes: prokaryotes and eukaryotes. A prokaryote is a cell without a nucleus and eukaryotes are cells that contain nuclei. There's one quick test to distinguish prokaryotes from eukaryotes: if you can see a single organism, it's a eukaryote.

A resident needs isolation precautions. Which will meet the person’s basic needs? Visiting the person as little as possible to p
malfutka [58]

The person’s basic needs Visiting the person as little as possible to prevent transmission. Thus, option "A" is correct.

<h3>What can you do to help meet the psychosocial needs of a resident in transmission-based?</h3>

Provide as much mental stimulation as possible by offering activities that the residents enjoy.

The people who are ensuring transmission-based precautions are required to feel mental peace. Mental anxiety, fear of infection, and stress can be some of the reasons for mental disturbances.

For such people, mental stimulation is necessary by allowing them to participate in recreational activities like fun indoor games.

Such activities will divert their mind from all the reasons for mental anxiety and people will feel relaxed.

Thus, option "A" is correct.
