1. Which of the following is an example of a primary sex characteristic?
emotionality
testes
breasts
body hair

The correct option is b) testes

Explanation:

Primary sex organs can be described as the organs which are directly involved in reproduction. These organs include the male and female gonads  i,e testes and ovaries, external genitalia.

On the other hand, secondary sex characteristics can be described as the features that appear during puberty in humans, and at sexual maturity in other animals. Breasts, facial and body hair, body fat deposits, vocal change all are secondary characteristics.

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.
