A runner has two pairs of running shoes. To find out which pair will allow her to run faster, she puts on the first pair and runs around the track once in exactly 2 minutes. She puts on the second pair and runs around the track again, this time, making it in 2 minutes and 10 seconds. She decides the first pair is better, and heads to the store to return the second pair. What are some constants in this experiment? (choose all that apply) (1 Punto) Type of shoe Track the runner is running on Distance the runner runs for each trial Time it takes to run around the track

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.
