Answer:
A factor of an experiment is a controlled independent variable; a variable whose levels are set by the experimenter. A factor is a general type or category of treatments. Different treatments constitute different levels of a factor
An experiment has several types of variables, including a control variable (sometimes called a controlled variable). ... A control variable is another factor in an experiment; it must be held constant. In the plant growth experiment, this may be factors like water and fertilizer levels.
Explanation:
Answer:
The unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
Explanation:
Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.
Therefore, the unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
<h2>Messenger RNA
</h2>
Explanation:
Messenger RNA results from the breakage and recombining of DNA strands that is known as transcription
- Transcription always starts at a specific site called promoter
- Promoter are specific sites on DNA where RNA Polymerase binds and initiates transcription
- Synthesis of RNA occurs in 5'-3' direction and continuous
- Only a strand of DNA act as template, template is also known as antisense strand or non coding strand
- The complementary strand is the sense strand or the coding strand
- Only a small segment of DNA is transcribed at a time generally called gene
