Question

Salt is dangerous to land snails. It will rapidly kill them. However, some populations of aquatic, freshwater snail have adapatations that allow them to live in a mix of salt and fresh water. This allows them to live in different parts of a river system. A group of scientists monitored salt concentrations in the habitats of two freshwater snail populations. They recorded the salt level as follows (in ppt, parts per thousand):Location 1 (Day 1): 0.1 ppt (morning), 0.0 ppt (afternoon), 0.1 ppt (evening)Location 2 (Day 1): 0.3 ppt (morning), 0.5 ppt (afternoon), 0.2 ppt (evening)In 3–5 sentences, describe in which population you'd expect to see more adaptations for salt water. Make sure to also explain how such adaptations would become more common in this population.(4 points) make this 4 sentences sound like a 6th grader and do NOT plagiarize

Answer 1

I would expect to see more adaptations for salt water in the snails from Location 2 because they live in an environment with higher salt levels. The higher salt concentration, like 0.3 and 0.5 ppt, means the snails have to deal with more salt, so they might develop traits that help them survive in salty water. Over time, the snails that can handle the salt better will live longer and have more babies. This means those helpful traits will get passed down, and the population will have more snails that are good at living in salt water.
