Peppered moth stimulation is an experimental setup that show the behavior of moth in relation to their environment. The objective of the setup is to stimulate changes in moth population as a result of pollution and predation.
Peppered moth stimulation relates to the survival of the fittest because the moth with the most adaptive ability will be able to survive despite the negative forces in the environment. The bright colored moth was able to survive the pollution in the environment and retains its colour while the black coloured moth change its colour to black due to the pollution int the environment.
During exercises, our muscles needed energy for contractions. The heart pumps more rapidly and more powerfully during this time for a few reasons.
First, more oxygen and nutrients like glucose can be transported to the heart. Muscle cells uses oxygen and glucose for aerobic respiration to generate energy.
Secondly, more carbon dioxide and waste can be transported away from the muscles. Waste products from aerobic respiration includes carbon dioxide or water etc. The faster the heart pumps, the faster the blood gets transported so more waste can be carried away.
Thirdly, lactic acid can be carried away too. When oxygen supply is not enough, the cells undergo anaerobic respiration to generate energy. This type of respiration does not require oxygen, but a waste product called lactic acid is produced. Lactic acid must be carried away from cells because they're harmful. Therefore, the faster the heart pumps, the more lactic acid gets carried away.
Last but not least, heat can be carried away too. Part of the energy generated is turned into heat. Therefore, in order to help us cool down, blood travels fast to carry heat away from the heat generating muscle cells.
Answer:
You can use a refractometer to measure sugar content in upripe and ripe bananas and evaluate how important the formation of sugars is in the ripening process. If other unripe fruits are available, expand this study to include these other fruits
False. Martin Luther King's Speech "I Have A Dream" was about his hopes for the equality in the American and African American Society. He was dreaming of a world where segregation is non-existent and all human beings are co-existing in society, functioning as equals.
