Dark-colored mice from two different populations living hundreds of miles apart were examined and the mice looked nearly identical. The dark color fur in the two different populations of mice was caused by two different genes. What does
this tell you? (Note: More than one answer is correct.)
Dark color fur evolved only once in rock pocket mice
Under similar conditions, natural selection can favor similar adaptations
Different mutations in two different genes cannot generate the same phenotype
There are at least two genes involved in creating dark-colored mouse fur
Dark fur color evolved independently on each lava flow

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.
