Salt is notoriously dangerous to land snails; however, some populations of aquatic, freshwater snail have brackish (or a mix of
salt and fresh water) water adaptations and live in different parts of a river system. A group of scientists monitored salt concentrations in the habitats of two freshwater snail populations located nearby and recorded the data as follows (in ppt, parts per thousand): Population 1 (Day 1): 0.1 ppt (morning), 0.0 ppt (afternoon), 0.1 ppt (evening)
Population 2 (Day 1): 0.3 ppt (morning), 0.5 ppt (afternoon), 0.2 ppt (evening)
describe how these results show why the brackish water adaptation may be necessary, and 2) explain how to determine whether the inherited adaptation is influenced by environmental factors.
The brackish water adaptation is clearly necessary because the aquatic snails need to live in an environment in which the river system has a higher quantity of salt than what land snails can take. I can determine that the environmental factors influenced the inherited adaptations because the second population has a higher salt concentration in their habitat compared to the initial population.
stored solar energy in phytoplankton, zooplankton, and other organic material
Explanation:
The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.
These are all true- Vacuoles might store food or any variety of nutrients a cell might need to survive but they can even store waste products so the rest of the cell is protected from contamination. They’re also larger in plants than in animals
