Answer:
B
Explanation:
Natural selection deals with adaptation to environment to survive better than less adapted and how their environment changes them.
1) variation in traits.
population of beetles: equal brown and green numbers in population.
2) differential reproduction.
Natural habitat is in trees. Green leaves hide green beetles.
The brown beetles are noticed by birds in the area.
Birds eat brown beetles.
More green beetles survive than brown beetles
3) heredity
Green beetles reproduce in greater numbers than brown beetles
4) end result
Beetle population changes from brown and green to mostly green beetles.
After leaving the source of emf, an electron's potential energy is lower.
<h3>Describe electromotive force.</h3>
The voltage or potential difference of a battery or other electrical energy source is known as the electromotive force. A resistor is where the emf is coming from. The potential energy of an electron will now be higher than the potential energy of an electron before it leaves the source emf.
Now, the potential energy of an electron before leaving the source of electric current will be greater than the potential energy of an electron after leaving the source of electric current because the resistor connected to the source of electric current will reduce the potential energy by converting some of the energy to heat.
