During the process of steel production, the flaws in steel casting are detected by A. ultrasonic vibrations. Ultrasonic vibrations are sound waves that have a frequency higher than human hearing. These sound waves are sent through a steel casting such as a part of a machine engine. If there are any flaws in the casting, the quality controller will be able to pinpoint where the flaw is and to determine the flaw's shape and size. This technology is integral to the manufacture of structurally sound steel castings
Answer;
They are both explanations of the rate of evolutionary change.
Explanation;
Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur.
-Gradualism is selection and variation that happens more gradually. Over a short period of time it is hard to notice. Small variations that fit an organism slightly better to its environment are selected for: a few more individuals with more of the helpful trait survive, and a few more with less of the helpful trait die.
-In punctuated equilibrium, change comes in spurts. There is a period of very little change, and then one or a few huge changes occur, often through mutations in the genes of a few individuals. Mutations are random changes in the DNA that are not inherited from the previous generation, but are passed on to generations that follow.
