Antibiotics that kill large numbers of gram-negative bacteria are primarily aminoglycosides and some higher generation cephalosporins. The major medical concern in antibiotic usage is antimicrobial resistance which can arise with improper use of antibiotics. On the other hand, higher generation antibiotics that are proven bactericidal can have more detrimental adverse effects for the patient.
Answer:
Basically the translation of CK-B protein is inhibited in the U937D cells, despite the fact that the CK-B protein is bounded to the ribosomes. This is because(<u>mechanisms)</u> the translation is inhibited by the binding of translational repressors to the 3’UTR of the CK-B mRNA rather than the actual CK-B mRNA 3'UTR.
Furthermore, the soluble protein inhibitions is due to the reaction of the U937 cells to the short RNA sequences with the 3’UTR.
<u>The introduction of these sequences(shot segement of RNA) </u>into the U937D cells leads to CK-B synthesis. This makes 3’UTR sequences to bind to the translational repressor proteins, thus preventing them from binding to the CK-B mRNA

A common feature of many eukaryotic mRNAS is the presence of a rather long 3' UTR, which often contains consensus sequences. Creatine kinase B (CK-B) is an enzyme important in cellular metabolism. Certain cells—termed U937D cells—have lots of CK-B mRNA, but no CK- B enzyme is present. In these cells the 5’ end of the CK-B mRNA is bound to ribosomes, the mRNA is apparently not translated. Something inhibits the translation of the CK-B mRNA in these cells. Researchers introduced numerous short segments of RNA containing only 3’UTR sequences into U937D cells. As result, the U937D cells began to synthesize the CK-B enzyme, but the total amount of CK-B mRNA did not increase. The introduction of short segments of other RNA sequences did not stimulate the synthesis of CK-B; only the 3’UTR sequences turned on the translation of the enzyme. Based on these results, <u>purpose a mechanism for how CK-B translation is inhibited in U937D cells. Explain how the introduction of short segments of RNA containing the 3'UTR sequences might remove the inhibition.</u>

Explanation:
Diarrhea can be caused by indigestion, a raw meal, or little bacterias found in almost anything we swallow, but if it doesn´t stop in a 12 hours period, it may be caused by some infection or a worse condition that need to be seen by a doctor, is this case, the nurse is concerned because Aidan is severely weakened, signal that is dehydrating very fast and that could cause him a worse condition such as hypotension, hypoglycemy or even losing consciouness.
Answer:
The correct answer is option C, that is, emotional.
Explanation:
According to Gardner's theory of multiple intelligences, all the individuals exhibit different types of intelligences. The different kinds of intelligences included in Gardner's theory of multiple intelligences are musical, naturalist, existential, logical-mathematical, bodily-kinesthetic, intrapersonal, spatial intelligence, linguistic, and interpersonal. Thus, emotional is not the type of intelligence included in Gardner's theory of multiple intelligences.
