Answer:
They are used as an indicator organism for pathogenic bacteria.
Explanation:
Coliforms are bacteria found in digestive tract of animals and humans. They are non-pathogenic, easy to culture and are used as an alternative indirect testing for presence of other microorganisms. Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.
Therefore the existence of coliforms in water easily indicates feacal contamination.
A habitat defines the interaction of organisms with the other factors, which can be living or non-living, while niche describes how that specific organism is linked with its physical and biological environment. Habitat is the part of the ecosystem, while niche plays an important role in the formation of an ecosystem.
Answer:
Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.
Explanation
Cells encounter osmosis due to their semi-permeable membranes. Water can flow past cell membranes. A given cell placed into distilled water will have some water flow into it, causing it to burst. A given cell placed in a very concentrated water will have some water flow out of it, causing it to shrivel. A given cell placed in a solution with the same concentration of minerals as the cell will have an equilibrium of water flowing in and out. This is the case of IV (Intravenous therapy) when we want to deliver substances into a human blood. We want to make sure the liquid delivered is as concentrated as the blood to avoid cell shriveling or bursting.
This picture above sums up the 3 cases cells could face in a solution.
Good luck!
