Answer:
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.[1][2] In 1978 Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."[3][4]
The dark-coloured or melanic form of the peppered moth (var. carbonaria) was not known before 1811. After field collection in 1848 from Manchester, an industrial city in England, the frequency of the variety was found to have increased drastically. By the end of the 19th century it almost completely outnumbered the original light-coloured type (var. typica), with a record of 98% in 1895.[5] The evolutionary importance of the moth was only speculated upon during Darwin's lifetime. It was 14 years after Darwin's death, in 1896, that J.W. Tutt presented it as a case of natural selection.[6] Due to this, the idea widely spread, and more people believed in Darwin's theory.
Explanation:
<h3><u>Answer;</u></h3>
Conditioning
<h3><u>Explanation;</u></h3>
- This was an example of classical conditioning. Classical conditioning is when two stimuli are linked together to produce a new learned response in a person or an animal.
- <em><u>An experiment done by Pavlov demonstrated classical conditioning in dogs. Such that; there was a neutral stimulus (the bell), which by itself will not produce a response, like salivation and also there was a non-neutral or unconditioned stimulus (the food), which will produce an unconditioned response.</u></em>
Answer: Since it's the DOMINANT allele that means that it will take over reccesive allele that's why it's shown.
Explanation: A heterozygous individual is an individual where the have both the dominant and reccesive allele for a trait. The dominant allele will always be stronger than the reccesive allele. This results in the dominant allele being shown.
