Answer:
Solution A-It will likely swell up since you put it in a hypotonic solution
Solution B- Since you placed it in a hypertonic solution, its gonna shrivel up and become smaller
Explanation:
Solution A- Placing Elodea cells into 100% water, which is more hypotonic than freshwater, also causes water movement into of the cells resulting in the swelling of the cells. ... As water moves out of the cells there is a loss of turgor pressure and the plasma membranes detach from the cell walls as the cells shrink.
B- When the Elodea was placed in the salt solution, the vacuoles disappeared and the protoplasm came away from the cell wall making the organelles appear to be clumped in the middle of the cell. ... Therefore, if it were placed in a hypertonic solution it would lose water and shrivel.
Hope this helps! Brainliest??Anyways have a great day my loves<3
(havent I already answered like 5 of your questions? lol)
Answer:
Nitrogen is present in the atmosphere in a molecule form about 78 percent. This nitrogen comes to the earth with the water through rainfall. Some nitrogen fix by beneficial microorganisms such as Cyanobacteria and Azotobactor which are present in the roots of higher plants. These microorganisms convert nitrogen molecule into nitrates and used by the plants. There are some other microorganisms which again convert nitrate into nitrogen molecules, called denitrifying bacteria and nitrogen molecule goes to the atmosphere again and complete the cycle.
