Answer:
See explanation below.
Explanation:
<em>Study Design - Partially double-blinded study</em>
- The <u>cohort study </u>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; <em>e.g.</em> water; saline solution) - <em>Control group </em>
- Cough treatment - <em>Experimental group</em>
Participant cough will be recorded <u>every hour</u> (until 8 hours are reached) for two consecutive days (for repetitions) in both groups using semiautomated ambulatory cough monitor and analyzed statistically.
Experimental group: <u>If coughing is significantly (statistical analysis) reduced within the 8 hours </u>(<em>after repetitions</em>) and a symptom improvement is observed, <u>the hypothesis that cough drops are effective is valid</u>.
Control group: To determine that cough drops treatment is effective, the no-treatment group should score worst and participant should not show significant improvement.
*<em>In scientific experiments, repetitions are important to prevent bias and error.</em>

Explanation:
Smaller cells, with a larger surface area to volume ratio, are more efficient for diffusing materials in and out because, as a cell grows, the volume grows faster than the surface area.
