Answer:
Ultraviolet radiation does not influence photosynthesis
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>
Mendel was the first person to succeed in predicting how traits are inherited from generation to generation.
Out of the following given choices;
contain ribose
consist of two strands
made of nucleotides
have an R group
The answer is 'made of nucleotides'. This is because out of the choices, DNA and RNA share the similarity of being made of nucleotides. However, while DNA is made of deoxyribose nucleotides, RNA is composed of ribose nucleotides. This difference is that in deoxyribose nucleotide, the 2nd carbon has a hydroxyl group while ribose nucleotide has hydrogen.
Answer:
limiting factor
Explanation:
In an ecosystem, certain factors hinder the growth or abundance of the population of organisms. These factors are called LIMITING FACTORS. Limiting factors, which can be biotic, food, drought, predation, disease etc, are factors that inhibits a population of organism from becoming enlarged. There are two types of limiting factors viz: density dependent (depends on size) and density independent (not dependent on size).
This is the case of a drought that dries up the stream that inhabits a population of salamanders. The drought causes the unavailability of water, which will ultimately have an effect on the growth of the salamander population. Hence, the DROUGHT is considered a LIMITING FACTOR.
