Suppose the sub-hypothesis that wing waving alone reduces predation by jumping spiders was supported by the Zonosemata experimen
Sliva [168]

Answer:

The correct answer is: <em>Zonosemata flies with housefly wings are attacked less frequently</em>

Explanation:

The Zonosemata experiment is a scientific experiment that was conducted to investigate how zonosemata flies are able to protect themselves from predation by jumping spiders. In this study, housefly wings were transplanted onto zonosemata flies. This made zonosemata flies protected from attack by jumping spiders. On the other hand, when zonosemata wings were transplanted onto houseflies, they were easy targets for jumping spiders. Therefore, if the sub-hypothesis that wing waving alone reduces predation by jumping spiders is proven, the logical result would be that:  Zonosemata flies with housefly wings are attacked less frequently.

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>

Butoxors [25]

Answer: Earth's rotation is slowing slightly with time,thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation. Atomic clocks show that a modern-day is longer by about 1.7 milliseconds than a century ago.
