Flowers of orchid species ophrys bombyliflora look and smell like female bumblebees. this attracts the male bumblebees flying nearby to the flowers. thus, pollen sticks to the head and abdomen of the bumblebee, which causes pollination. this orchid species is only pollinated by these bees, which is why the species is known as bumblebee orchids. what mode of evolution is represented by this example?

The mode of evolution that is represented by this example is called coevolution. Coevolution is the process in which two independent species influence the evolution of each other. This process involves natural selection. There is nothing working as a forcing agent. Since this orchid named bumblebee orchid is totally dependent on a single species named bumblebee for its pollination and this evolution process, so this process is called coevolution. Various other organisms also follow this method of pollination to continue their cycle of evolution.

Both prokaryotic and eukaryotic cells have ribosomes and cell membranes

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
