PATTERNS OF EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bees don’t see red, but do see yellow, blue, and ultra-violet light. Thus, bee-pollinated flowers are mostly yellow or blue with UV nectar guides (landing patterns) to guide the bee. They usually have a small, narrow floral tube to fit the tongue-length of that species of bee.
A
Convergent Evolution
B
Divergent Evolution
C
Coevolution
Explanation: 

Detailed explanation-1: -The Role of The Flower Flowers rely on bees to cross-pollinate their female plants. When bees feed on the pollen, their body picks up excess via their pollen-collecting hairs, which is then released when they land. Pollen act as the flower’s seed, which is mandatory for the survival of that flower species.

Detailed explanation-2: -As the bees enter the flower to collect the nectar, the pollen grains stick to its body and get transferred to the stigma as the bee approaches another flower. Therefore, bees pollinate the plants producing nectar as it needs the nectar for producing honey.

Detailed explanation-3: -When they land in a flower, the bees get some pollen on their hairy bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating* the plant. This benefits the plants. In this mutualistic relationship, the bees get to eat, and the flowering plants get to reproduce.

Detailed explanation-4: -The Galpagos tortoises share a common ancestor, but have necks of different lengths to best reach the food they need in their environment. This kind of evolution is proven by DNA analysis and results in organisms with different ancestors becoming more alike as they adapt to similar environments.
