Answer:
Plant cells deal with osmosis by being enclosed in a cell wall.
Animal cells use active transport systems to deal with the problem of osmosis.
Fresh water protists have contractile vacuoles to deal with osmosis.
Many bacteria have cell wall to protect them from osmosis.
Explanation:
Plant cells have a rigid cell wall. If a plant cell is places in a place where the conditions are hypotonic, then the cell will tale up water by osmosis but the cell wall will prevent it from bursting. This condition is termed as the cell being 'turgid'.
As animal cells do not have the rigid cell wall, they use the mechanism of active transport system to stop the cell from bursting during osmosis. In this process, ions are moved out of the cell so that the pressure in the cell due to osmosis can be reduced.
Fresh water protists have a structure present in them called as the contractile vacuole. The contractile vacuole has the capability to remove any excess water from the cell as well storing water if there is not enough water.
Bacteria have peptidoglycan cell walls to prevent osmosis.
A keystone species helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether.
Answer:
<em>Organisms that are eaten by the mayfly will increase.</em>
<em>Organisms that eat mayfly will decrease at first.</em>
<em>Organisms that eat mayfly would consume more of other organisms in their diet</em>
Explanation:
her get killed or they will migrate from the stream that is polluted. The population of the organisms on which the mayfly larva fed would increase as it will have a lesser number of predators now.
On the other hand, the organisms which fed on the mayfly would decrease at first as they will have a lesser amount of food available. They might find another source of food in order to survive.
If a person does not consume the minimum daily requirement of carbohydrates then the body will use stored glycogen and the person will look unhealthy and become weak after some time.
<h3><u>
Importance of carbohydrates</u>
: </h3>
- Like other nutrients, carbohydrates are also very essential for various functions of the body.
- Carbohydrates such as glucose are required for instant energy and day-to-day activities.
- If there is no or less amount of carbohydrate in the body then our body will start converting the glycogen that is stored in the liver into glucose.
- After some time, the person will start to appear unhealthy, thin and weak if there is no minimum daily requirement of carbohydrates is met.
