Answer:

B. a light bulb burned out and "closed" the circuit.

Explanation:

Unscrew one bulb. If the other bulbs turn off, it is a series circuit. A light bulb glows when electrons flow through it. As the electron flow increases, the brightness increases.

When lights are attached in parallel, each light is on its own circuit to the power source. If one filament burns out, it has no effect on the remaining lights, as they each continue to be in a closed circuit with the power source.

Which of the following is digested first?<br><br> protein<br> starch<br> fat<br> sugar
Reika [66]
Answer:
Starch

Explanation:
Digestion begins in the mouth. The teeth break down food from chewing through mechanical digestion.

Chemical digestion also begins in the mouth. Saliva moistens food, but it contains an important enzyme called amylase. This enzyme breaks down starch into simple sugars.

So, the first compounds that are digested are starch.
