The rising phase of the AP is due to opening of voltage dependent Na channels. The falling phase of the AP is due to opening of voltage dependent Na channels. The rising phase of the AP is due to closing of transmitter-dependent K channels. The falling phase of the AP is due to closing of transmitter-dependent K channels. The rising phase of the AP is due to opening of voltage dependent channels other.than Na or K. 8.
Flight is a characteristic of all birds and some mammals.
Male 3 spined stickleback fish are highly aggressive, particularly during mating season. Each male sets up his own individual territory which he vigorously defends from other males. The following experiment was performed to assess aggression in these animals. Sticklebacks were presented with the models shown below. Next to each model is the percentage of sticklebacks which responded to the model with aggressive behavior.
