Hypotonic solution means a solution with a higher water potential than the cell
isotonic is the solution with the same amount of water potential with the cell
in animal cell, it only has a semi permeable membrane, therefore when put in hypotonic solution, water molecules will move from the solution to inside the cell by osmosis. the cell may gain so much water that it may burst
in isotonic solution, the net movement of water molecules will be same in each direction , as the water potential is same. that way the cell will not gain or loss water and remain it oiriginals shape
however in plant cells, it has a cell wall. it prevents the cell from bursting. so when put in hypotonic, the cell gain water,but not burst, the cell membrane just push against the cell wall and the cell become turgid
in isotonic solution, same animal cell , no change
Answer:
According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
Answer:
Evolution
Explanation:
Natural selection is usually defined as a process by which an organism or a specific type of living species adapts to a new environment in order to grow, develop, reproduce and protect themselves from the predators. During this time of migration, evolutionary changes occur in organisms over a specific period of time. It occurs naturally and there are several factors that affect these changes occurring in an organism.
Evolution simply refers to the growth, development, and expansion of an organism that occurs over a definite time period.
I think it’s E (microtubules) i can be wrong but hopefully this helped
Answer:
The correct option is H) these acids change the environment.
Explanation:
Soil can be described as the part of the environment where plants grow. In primary succession, life stars arising in an area which has no soil and only rocks, This is possible because lichens are the organisms which can grow on the rocks. Lichens secrete certain acids which break down these rocks and hence soil begins to form when these rocks break. This makes it possible for other plant species to grow on these lands.
