If the length of the absolute refractory period in cardiac muscle cells was the same as it is for skeletal muscle cells,
a) it would be much longer before cardiac cells could respond to a second stimulation
b) contractions would last as long as the refractory period pacemaker cells would cease to spontaneously depolarize
c) tetanic contractions might occur, which would stop the heart's pumping action

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
