Both species can grow to 3 ft 6 in ( 1. 07 m ) and can weigh up to 46 lb ( 21 kg ).

Both these species occur in a normal, a black and a rare white morph, confirming the view that simply dividing into species based on morph ( as had been done earlier ) is incorrect.

Both the lower pH and higher aluminium concentrations in surface water that occur as a result of acid rain can cause damage to fish and other aquatic animals.

Both aldoses and ketoses occur in an equilibrium ( starting with chain lengths of C4 ) cyclic forms.

Both reactions are catalysed by the same active site and occur via transesterification, without a covalent protein-DNA intermediate, in contrast to reactions catalysed by Ser and Tyr recombinases ( see site specific recombination ).

Both migrations occur at incisive periods, the Mycenaean at the transition to the Late Bronze Age and the Doric at the Bronze Age collapse.

Both may occur together in the same example, depending on the relevant point of view.

Both outcomes cannot occur for a single trial ( i. e., when a coin is flipped only once ).
