Which is the best definition of directional selection?

a process by which two species can no longer reproduce

a process by which one of the extreme variations of a trait is favored

a process by which individuals with either extreme of a trait are favored

a process by which average individuals in a population are favored

question 1:

senate and house of representatives

i would try to answer the second question but i’m not 100% positive but i hope i

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.
