Trimethoprim-sulfamethoxazole (TMP-SMX) are a class of antibiotics used in the treatment of bacterial infections due to their inhibitory actions in the folic acid biosynthesis pathway of bacteria.

<h3>What is TMP-SMX?</h3>

Trimethoprim-sulfamethoxazole (TMP-SMX), otherwise known as co-trimoxazole, is a combination of two antimicrobial agents that work synergistically to inhibit the enzyme systems involved in the bacterial synthesis of tetrahydrofolic acid.

They are used in the treatment of urinary tract infections, respiratory tract infections, cholera, etc.

They can be administered intravenously or orally.

Therefore, Trimethoprim-sulfamethoxazole (TMP-SMX) are antibiotics used in the treatment of bacterial infections.

Classify each description as true of introns only, exons only, or both.A-present in eukaryotic genomesB-generally absent from ba
maxonik [38]

The right answers are:

A-present in eukaryotic genomes ==> Both exons and introns

B-generally absent from bacterial genomes ==> Introns

C-part of the final mRNA strand ==> Exons

D-code for an amino acid sequence ==> Exons

E-removed from initial mRNA strand prior to translation ==> Introns

F-present in the DNA used as the template for transcription ==> Both exons and introns

In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.

Which of the following occurred because of Flint's water crisis? Select the three correct answers.
STatiana [176]

1, 2, 3

Because of Flint's water crisis;

  1. The number of children with lead poisoning doubled.
  2. General Motors stopped using Flint's water due to corrosion of their machinery.
  3. Dozens of people contracted a form of pneumonia known as Legionnaires' disease.

Explanation:

In a bid to save money, Flint City Council resolved to switch its water supply to the city in 2014 and also switching from the Detroit Water and Sewerage Department (DWSD) as a provider to Karegnondi Water Authority (KWA). During the process of switching, water from Flint River was used as a temporary source of water for the residents. This water was however not treated and caused corrosion of supply pipes which led to the leakage of lead into the water supply. The water was also filled with other mineral contaminants that made the water hard and later high levels of chlorine were detected. This also caused General Motors to stop using the water because it corroded its machines.

The levels of lead caused lead poisoning especially to children while dozens of adults suffered Legionnaires' disease a form of atypical pneumonia caused by<em>  Legionella </em>bacteria in the water. The city officials did not warn residents in time even after com0lanit of foul smell and redness of the water supply.

<span>Plant cells will also change with the degree of specialization. It means that when is is a higher developed organism then it will have a higher degree of specialization. For the second question,Somatic cells of animal callus are most common to the plant cell. It is because just like a callus, the tissue of the plant cells are thick and it serves them as protection from friction.</span>
