Explanation:
Regular reflection happens when light reflects off an awfully smooth surface and forms a clear picture.
Diffuse reflection happens when light reflects off a unpleasant surface and forms a hazy picture or no picture at all.
Answer:
The population has evolved because there was a change in allele frequencies.
Explanation:
The evolution may be defined as the process of the change of the species characteristics with the passage of the time. The natural selection, mutation and the genetic drift might cause the evolution.
The population might have evolved as the allele frequencies has changed from the generation to the generation. Although the variation among the population is quite less but the variation is still enough for the evolution of the elephant seals.
Thus, the correct answer is option (D).

along the same direction the wave travels
Answer:
The force of air resistance clearly depends on the velocity of an object moving through the air: the larger the speed, the larger the drag force.
Explanation:
As learned above, the amount of air resistance depends upon the speed of the object. ... Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.
