Answer:
A. A light burned out and "opened" the circuit
Explanation:
In a parallel circuit if a light bulb goes out the rest are fine because they each have independent routes to the battery. But in a series circuit when a light bulb goes out the rest goes out because the current is going in one pathway. To tell the difference of if it closed or opened the circuit, you have to know what they mean. Closing a circuit means a complete electrical connection, the light bulbs will light and electricity will flow. Opening a circuit means the opposite. If the all the light bulbs have stopped working then the circuit is not complete, therefore it's open.

A continents size may move in the way of a current. But most of those are what the average person calls waves on a beach.
Depending on the ecosystem, various things could happen. For example, if you introduced it to a forest/mountain area (Northern USA) a large cycle would change. Within 15 years, the mountain lions would prey on deer, mice and rabbits. The decrease in those populations would lead to an increase in plant wildlife. The variety in new plants could bring new animals like wild bison or even beavers.
Hope this helped.
Hello!!
-A local conservation issue would be endangered species/animals. With the amount of animals that are on the endangered/threatened species list decrease the amount of food that we can eat, such as fish. Fish produce calcium carbonate, which helps lower the amount of CO2 produced and keep the waters from becoming too acidic. If you save the fish, you could also help save the environment.
Reflect:
-I chose this topic because this is something that should be paid more attention to help save them.
-I can stop overfishing so the fish can help keep down the amount of carbon and acidity in the water.
-Explain how they help our oceans/waters. Persuade people to stop overfishing and depleting the amount of fish in our waters.
I hope I helped!! This was just to give you a couple of thoughts. Add more on if you want to. Have a great night, Pjj3!! :)
