Answer:
D. trait formation due to behaviors
Explanation:
It is obvious to see that the three animals, cat, whale, and bat, have the same basic structure of their forelimbs, but also that they have developed differently and have taken a new shape. The reason for this is a trait formation due to behavior. The cats ancestors were terrestrial, and the cats have remained terrestrial, walking on their four legs, and having the same shape and function as their ancestors. The whales had similar forelimbs, but their ancestors started to move more and more in water. As they did, they needed more muscle power, but also greater width of the forelimb so that they can move more easily and more efficiently in the water. This behavior has gradually resulted in a flat, strong, peddle like forelimb. The bat too had similar forelimbs to that of the cat, but its ancestors started to try to fly. The process was gradual, and it started with jumping, then longer jumps, development of skin between the fingers, elongation of the fingers, thus provide more area for development of wider skin area. This has resulted in developing a light, wide, skin dominated forelimb with elongated fingers, providing flight for the bat.

Answer: The wavelength of light increases.
Explanation:
As we proceed outward from the innermost band of the rainbow the wavelength of light increases.
when light travels through a prism, the wavelengths separate into different colors (which are colors of the rainbow). These colors are Red, Orange, Yellow, Green, Blue, Indigo and Violet. Each color has a different wavelength. Violet has the shortest wavelength of about 380 nanometers and red has the longest of about 700 nanometers. When you look at a rainbow, the innermost portion has a violet coloration while the outer most is red, hence the wavelength of light increases from the innermost band to the outermost. That is, from about 380 nanometers to about 700 nanometers.
