Algal cells are placed in an isotonic solution. additional amounts of solutes are slowly added to the solution. what happens to the cells ?

water moves out of the cell and it undergoes plasmolysis

Explanation:algae cells are plant cell.they have chlorophyll, carotenoids and phycobillins as their photosynthetic pigments.

They also possesses cellulose cell walls .

During osmosis,water moves from a region of low concentration of solute to a region of high concentration of solute.

In the above case,both the algae cell and it's surrounding solution has the same concentration of solute . however as solute is added to the solution it becomes more concentrated and water moves out of the algae cell .As the cell continues to lose water,the cell body pulls away from the cell wall causing a phenomenon called plasmolysis.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

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.
