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.
The pigment that traps energy is Chlorophyll.
Chlorophyll is a green pigment commonly found in almost all
plants, algae and cynobacteria. Leaves appear green because they contain this
pigment. This pigment absorbs the light energy from the sun to complete the
process of photosynthesis or food production of plants. Chlorophyll is said to
absorb light in the long wavelength and blue in the short wavelength regions of
the visible light spectrum. Green light is not absorbed, thus making the leaves
of some plants green. Chlorophyll is found at the plant’s chloroplasts, which
comes to have different structures.
There is no particular number, you have to find it through an equation: I.M.A. = Radius (wheel) / Radius (axle)
