During the dna isolation procedure, your cheek cells were lysed (popped open) by placing them in a solution that had a lower solute concentration than the cell cytoplasm. the best term for this procedure would be hypotonic lysis hypertonic lysis isotonic lysis concentration-independent lysis

The correct answer will be option- Hypotonic lysis

Explanation:

Lysis process is the breaking down of the membrane of the cell by osmotic and enzymatic mechanisms.

In the given question, the lysis process has been performed using the osmotic mechanisms as the cell was placed in the solution with a low amount of solute thus the high amount of water called hypotonic solution.

When the cell was placed in the hypotonic solution, the water moved inside due to the difference in the concentration gradient which resulted in the swelling of the cell which leads to the rupture of membrane.

Thus, Hypotonic lysis is the correct answer.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
