Non-disjunction is the failure of homologous chromosomes to separate during meiosis i, or the failure of sister chromatids to separate during meiosis ii or mitosis. as a result, both homologous chromosomes or both sister chromatids migrate to the same pole of the cell. this produces daughter cells with an imbalance of chromosomes. if 22 pairs of homologous chromosomes segregate normally during meiosis i in humans (n=23) but we have non-disjunction of 1 pair, then at the end of meiosis ii we will have

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.
