Many flowering plants have a color pattern known as a UV bullseye. When viewed under ultraviolet (UV) light, the bullseye shows up as a dark spot in the center of the flower, close to the nectar and the pollen. The bullseye also absorbs UV radiation from the sun and protects the plant, similar to how melanin in humans protects against sunburn. a. Many bees have UV light receptors in their eyes. Describe the advantage of this adaptation to the bee AND to the flower. b. Flowering plants that live in hotter environments tend to have larger UV bullseyes. In fact, some UV bullseyes are so large that the entire flower looks dark under UV light. Describe the tradeoff of having a large UV spot. Note that "tradeoff" means one advantage and one disadvantage.

Pakicetus is an ancient wolf-like organism that lived 50 million year ago. It had wolf-like ears and nostrils on the front of its skull. Modern whales have a similar ear structure, but their nostrils are on the back of their skull. Aetiocetus lived 25 million years ago, had the same ear structure as both Pakicetus and modern whales, but nostrils in the middle of its skull. According to this information, the most likely conclusion that biologists could draw about the relationship of Aetiocetus to the other organisms is that Aetiocetus is a transitional form between Pakicetus and modern whales. evolved as whale ancestors lost their forward-placed nostrils through disuse. is the ancestor of both Pakicetus and modern whales. is not related to either Pakicetus or modern whales.
