In the context of scientific approach, the role of data is central as well as fundamental when scientists search for observations which would either verify or reject their ideas regarding the world.

The scientific approach follows a systematic order in which theories or hypotheses are tested through experiments and observations are recorded. These observations are in the form of raw data which are then analyzed by scientists.

Analysis of the data leads to the generation of information which can be utilized suitably to develop an insight about the subject of interest. This information is helpful in determining whether an idea or theory is substantial or not.

In which statements regarding medications taken by a client diagnosed with copd do the the drug name and the drug category corre

emmainna [20.7K]

There are choices for this question namely:

a) Ciprofloxacin is an antibiotic.
b) Decadron is an antibiotic.
c) Bactrim is a bronchodilator.
d) Albuterol is a bronchodilator.
<span>e) Prednisone is a corticosteroid.
</span>
The correct answers are "ciprofloxacin is an antibiotic", "albuterol is a bronchodilator", and "prednisone is a corticosteroid". Ciprofloxacin is an antibiotic in the class of fluoroquinolones, effective against respiratory infections since patients with COPD has mucus hypersecretion which predisposes the patient to respiratory infections. Other antibiotics include respiratory fluoroquinolones such as levofloxacin and moxifloxacin, cephalosporins such as cefuroxime and ceftriaxone, and beta-lactams such as co-amoxiclav. Albuterol is a short acting beta-agonist (SABA) which actions as a bronchodilator by relaxing bronchial smooth muscles. Other popular SABA is salbutamol. Prednisone is a corticosteroid which actions to prevent inflammation by blocking the arachidonic acid pathway and therefore block the formation of inflammatory mediators.

Decadron is dexamethasone which is a steroid. Bactrim is TMP/SMX which is an antibiotic.

The histone proteins are among the most slowly evolving proteins. For example, a histone protein called histone H4 in cows and p

juin [17]

The statement is true, histones are proteins that are high in the amino acids lysine and arginine, making them extremely basic in their structure.

Histones control the degree of packaging of DNA during the processes of gene expression, replication or repair of hereditary material, among many others.

Histones H2A, H2B, H3 and H4 are small and basic proteins that are highly conserved in evolution and are composed of a globular domain at the carboxy-end, and by regions known as "tails", which are found at the amino-terminal end.

These tails are high in the amino acids lysine and arginine, which give them a positive charge.

This region is the site of numerous post-translational modifications that, it has been proposed, would modify the histone charge, altering the accessibility of the DNA and the protein / protein interactions with the nucleosome.

Chromatin compaction occurs due to the interaction between the negative charges of DNA and the positive charges of amino acids, mainly located on the tails of histones H3 and H4.

Therefore, we can conclude that the modifications on the amino acids lysine and arginine that form the basic part of the histone structure alter their functions.

Using the receptors on their surface and through the facilitation by immunoglobulins that attach to the foreign matter, macrophages 'hold' the foreign bodies in the body and 'ingest' them through phagocytosis. Lysozymes in the cells then in 'digest' the foreign matter.
