We have to find the force of gravity of an object that has a mass of 20 kg and then to choose the correct answer. The formula for the force of gravity is: F = m * g, where m is the mass of an object and g is the acceleration of the gravity ( on Earth : g = 9.81 m/s^2 ). F = 20 kg * 9.81 m/s^2 = 196.2 N, or approximately 196 N. Answer: A. 196 N<span>.</span>
Answer:
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.
