Punctuated equilibrium is defined as a theory in the evolutionary biology in which it states that when one specie appears in the fossil record they will become stable, and that it will only show little evolutionary change for most of their geological history. Therefore, the option that cannot be the result of punctuated equilibrium is extinction and coevolution. The correct answer is option A.
<u>Answer:</u>
<em>Instantaneous velocity is equal to speed of the object at that particular instant.</em>
<u>Explanation:</u>
Instantaneous velocity is the velocity of the object at that particular instant. It is also equal to speed of the object at that instant. It can be calculated by drawing a tangent to the position-time graph at that point and finding the tangent’s slope.
The first option ‘The ratio of change in position to the time interval during that change’ gives the average velocity of an object and not speed. Similarly the second option ‘the absolute value of the slope of position time graph’ gives the average speed.
