List three changes of state during which energy is absorbed.
mote1985 [20]

The three changes of state during which energy is absorbed are:

1. Change from solid to liquid - Melting.

2. Change from liquid to gas - Vaporization

3. Change from solid to gas - Sublimation

All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.

Which of the following is true of rods?
Alex17521 [72]

Answer: A - Rods are more numerous than cones

Explanation: Rods are found everywhere in the retina except the fovea (a tiny pocket in the retina where just about all of the cones are located).

B. The macula lutea is another word for fovea, no rods are found there.

C. Rods are utilized in low-light conditions and are not <em>sensitive</em> to wavelengths of light.

D. Cones are responsible for perceiving color and not rods.

E. The main function of the rods is to help us see in low-light conditions (scotopic vision), so this answer would be incorrect.
