Answer:

The pair's options needed to complete the question are

A. dog and cat

B. lion and dog

C. lion and cat

D. cat and mouse

E. they are all likely to be the same

D. CAT AND MOUSE IS THE ANSWER

Explanation:

Mass-specific basal metabolic rate (mass-specific BMR), is the resting energy expenditure per unit body mass per day.

mass-specific BMR mammals decreases as weight increases i.e

Metabolic rates of animals are allometric functions of body size

D. Cat and mouse is the answer

Answer:

The correct answer is option - C. The tomato yield at the end of the growing season

Explanation:

The dependent variable in research or an experiment is the factors that are being affected by the independent variables. The dependent variable is being tested or measures in an experiment and its measurement alter with the change in an independent variable.

In this research amount of the fertilizer is an independent variable that effect different dependent factors such as temperature, plant size, and sunlight but the tested variable that is tomato yield at the end of the growing season tested by weighing.

Thus, the correct answer is option - C The tomato yield at the end of the growing season.

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.
