Question 2<br> A carbohydrate energy storage molecule found in animal liver and muscle cells is:
Anna71 [15]

Answer:

Glycogen

Explanation:

Glycogen is a storage polysaccharide, which means it is made up of a chain of many monosaccharides. It is a storage polysaccharide because it is stored in the liver and muscle cells to be used as a source of energy later on.

Our body uses glucose for energy, but when it is not used up, it is stored in the liver and made into glycogen. When the body needs an extra boost of energy, it will use glycogen, especially when there is no other source like glucose, around.

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:

<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:
  1. No medication (natural drops; <em>e.g.</em> water; saline solution) - <em>Control group </em>
  2. Cough treatment - <em>Experimental group</em>
  • Data to be collected:

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.

  • Observations:

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>
