The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution. Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."
Answer: True?? or is it false?
Answer:
To prevent or limit bacterial contamination of the collected blood
Explanation:
The first few milliliters of blood have been reported to have a high probability of bacterial contaminant from the skin. Several studies have shown that diverting the first 10 to 30 milliliters of blood from a donor into a special pouch is effective in limiting the chances of collected blood being contaminated with bacteria.
<em>Hence, the purpose of the procedure is to limit the bacterial contaminant that will enter the blood collection bag.</em>
