1. Who were the first to discover or alter the study of animal behavior?

Charles Henry Turner, a zoologist and scholar, was the first person to discover that insects can hear and alter behavior based on previous experience.

Explanation:

Charles Darwin is my guess

Explanation:

The origins of the scientific study of animal behaviour lies in the works of the  British naturalists John Ray, Charles Darwin and French naturalist Charles LeRoy.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
