Jumping Jack Flash is a champion racehorse. A special diet and daily exercise have made him the fastest horse in the country. In
the wild, Jumping Jack Flash would survive longer than other horses because of his speed. Is this an example of natural selection? a. Yes, because he is very well adapted to his environment.
b. Yes, because his speed is the result of a random event.
c. No, because his speed is a result of diet and exercise, not a genetic trait.
d. No, because slower horses are better adapted to the environment.
c. No, because his speed is a result of diet and exercise, not a genetic trait.
Explanation:
Natural selection is the differential survival and reproductive success of some individuals of a population. This is attributed to the presence of beneficial genetic variations in them. Natural selection always targets the adaptive genetic traits. In the given example, a specific diet and exercise led to increased fitness and survival chances of Jumping Jack Flash. Diets and exercises are not genetic traits on which natural selection can be operative. Therefore, it is not an example of natural selection.
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
