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:
Genetically modified crops are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.
It should be a food web, because there are various producers and consumers, and the bears and humans eat each other
Answer:
C. The enzyme changes shape and is no longer able to bind the substrate.
Explanation:
The change in heat changed the size of the enzyme. The enzyme changed size and shape which made it incapable of bonding with the substrate.
