The isolation and therapy of suggestive individuals, joined with the detaining of individuals that have a great chance of having been tainted, establish two commonly used pandemic control measures. Although retirement is apparently always a acceptable public fitness measure, quarantine is more debatable. Mass quarantine can inflict important social, psychological, and economic values without appearing in the exposure of many infected individuals.

A television advertisement claims that a certain brand of cough drop reduces coughing for 8 hours. Describe an investigation tha

Liono4ka [1.6K]

Answer:

See explanation below.

Explanation:

Study Design - Partially double-blinded study

The cohort study will be composed of 80 adults (aged ≥18 years) with a clinical diagnosis of constant coughing present as a result of a cold, which would be measured by semiautomated ambulatory cough monitor.

This study will be divided into an experimental group and a control group:

No medication (natural drops; e.g. water; saline solution) - Control group
Cough treatment - Experimental group

Data to be collected:

Participant cough will be recorded every hour (until 8 hours are reached) for two consecutive days (for repetitions) in both groups using semiautomated ambulatory cough monitor and analyzed statistically.

Observations:

Experimental group: If coughing is significantly (statistical analysis) reduced within the 8 hours (after repetitions) and a symptom improvement is observed, the hypothesis that cough drops are effective is valid.

Control group: To determine that cough drops treatment is effective, the no-treatment group should score worst and participant should not show significant improvement.

*In scientific experiments, repetitions are important to prevent bias and error.

If the sequence of bases on the mrna codon is auu what would be the sequence of bases on the trna anticodon

Klio2033 [76]

Answer:

uaa

Explanation:

An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.
