Which of the following will allow for the greatest reduction in an individual’s carbon footprint?
goldfiish [28.3K]

The carbon footprint can be decreased by a great amount if the incandescent bulbs are replaced with the compact fluorescent bulbs. The compact fluorescent bulbs uses approximately seventy five percent less energy than the incandescent bulbs as they do not use heating mechanism to light. This leads  to less emission of the green house gases and thereby reducing the carbon footprint.

Hence, the correct answer is 'option a - replacing incandescent bulbs with compact fluorescent bulbs'.

nikdorinn [45]

Answer:

Motor nerves

Explanation:

Pulling the leg quickly from the sharp object is an example of reflex action. It includes sensory receptors, sensory neurons, interneurons, the control center (spinal cord), motor neurons and effector.

As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.
