Sometimes, new but well-tested experimental result may go against commonly accepted scientific ideas. which statement best justifies the need to revise the existing ideas when this happens? a) scientific theories continually change over a period of time. b) a scientific theory must explain as many findings as possible. c) accepted scientific ideas are usually based on the latest experiments. d) the new results usually show that the accepted ideas were completely wrong.

The correct answer is A) Scientific theories continually change over a period of time.
Throughout the history of science, there have been numerous theories and experiments that were well-tested and explained but were contradicting the current scientific consensus. It is often very difficult for the scientific community to accept revolutionary ideas like Darwin's theory of natural selection, or Einstein's theory of relativity because those ideas challenge the common understanding of science. But, in order for science to progress and thrive, new ideas and findings should always be taken into consideration.

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.
