The long term effects of competition on populations of two different species competing for the same source are as follows:
1. It becomes a situation of the survival of the fittest. For example, if two populations of plants compete for the same source, the stronger of the two species will overpower the weaker of the two species. Trees that grow taller will block out the sun and the smaller trees will die. In the animal kingdom, the strongest of the predators that compete for the same prey will survive.
In a typical ECG (Electrocardiogram) the first wave obtained is P wave; The P wave represents the depolarization of the atria. After this, the QRS complex is formed. The QRS wave represents the depolarization of the ventricles. During the depolarization phase, the ventricles contracts and pushes the blood into the atria. Hence, the correct answer is depolarization of the ventricles.
I believe that last one is true (photosynthesis of plants)
good luck
