All mentioned complexes (receptor-hormone, antibody-antigen, enzyme-substate) are involved in a molecular recognition.The molecular recognition involves <span>non-covalent </span> interaction between molecules. To form complex, molecules must be complementary in shape and charges, and usually, they are compared to key and lock. This way, the selectivity and specificity of recognition between molecules are assured.
Well 1m = 100cm
so 6m = 600cm. 600cm > 63cm. Hence, 6m is greater.
Streams or rivers form when water that does not find an underground aquifer, drains off the land by either seeping through the soil or spilling over the surface into the river or stream bed.
The answer is interconnected. You will come to find that everything that makes life possible on earth is all interconnected. It is just like the way all the human activities and necessities for the everyday life are all interconnected to nature.
