The main responsible for the delay among the atrial and
ventricular contractions is the action potential conduction velocity of the AV
node cells. If the atria and ventricles contract simultaneously, atria cannot
give any help in filling the ventricles, which is needed, especially in those
with stiff ventricles as in the elderly. Hence atria have to contract first and
then the ventricles.
They can be described through GENOTYPE because dominant always shows through phenotype.
Answer:
True
Explanation:
The formula for density is
p = m/v
density = mass ÷ volume
The answer is transverse wave
