Based on the equation

You are a scientist researching chemicals that affect corn plants. Among the chemicals that you have tested on your corn plants is one that, once applied to a plant, causes it to lose all of its chlorophyll, stop photosynthesizing, and eventually die. With a little more research, you are able to determine that its mode of action is to halt the production of carotenoids in the plant. (3 pts) a) Why are carotenoids important in plants?  b) Why would losing carotenoids cause the issues listed above? 

In a properly-wired 110-120-volt polarized and grounded household outlet, what is the shape of the grounded slot (neutral)?

Assuming correct color-coding of the wires, which outlet is wired correctly in the image?

Which term refers to an explosion of molten material caused by high-amperage arcs?

Which term refers to a single grounded wire (a.k.a. neutral, white or gray wire) that serves more than one ungrounded wire/conductor?

In the image, which wire should be used as the equipment grounding wire?

Which term refers to a device that disconnects voltage to a circuit manually (through a switch) and automatically (when a maximum current is exceeded)?

Which term refers to the voltage that a grounded part should have (i.e., zero volts relative to ground)?

Which term refers to an object or system of objects that create a direct connection to earth (e.g., a metal plumbing system, a re-bar system in concrete, a series of copper grounding rods, etc.)?
