Why are non-covalent interaction between substrate and active site important?

The active site and the substrate interaction is transient and non covalent. The distribution of charge of the active site and the substrate must be complementary of one another. The meaning of the complementary is that the postive and negative charge of should be cancelled out by one another or there will be repulsion in active and the substrate. This repulsive force will separate the site and substrate.

The non covalent bond such as vander walls, hydrogen bond and other interaction allow the the active site to get free after the reaction as these bonds are easy to separated after the reaction.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
