Answer:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... The denser cold liquid or gas falls into the warm areas.
Answer: The correct answer is-
C. a species evolves at a slow, steady pace.
Gradualism can be describesd as a pattern/ theory of evolution by which already existing species give rise to new species by means of slow/ gradual and steady changes instead of major and abrupt changes.
Over long period of time, the small changes (that are beneficial for their survival) result in new species.
Example- Tiger that is evolved pattern of stripes ( which give them better advantage to hide in tall grass).
Thus, option C) a species evolves at a slow, steady pace. is the right answer.
