Over time, some organisms have co-evolved so they mutually benefit and depend upon one another. many plants, for example, have developed adaptations in order to attract specific animals that can spread their pollen or seeds and ensure the plant's reproductive success. which of the following is an example of this type of co-evolution? a. a flower develops a musty odor and only opens at night to attract nocturnal bats with a similar odor. b. a flower develops a yellow and blue color, so it can be seen by bees which are attracted to these colors. c. a flower develops a large, flat surface to attract butterflies that prefer to perch as they feed. d. all of these

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
