I would personally say stem cells as your answer.
Answer:
the major problem was the lack of language standardization, which prevented nomenclatures from being discussed around the world between scientists and scholars.
<span>A spill of fuel oil which occurred near the Wild Harbor salt marsh in 1969, affected and contaminated salt marshes with up to 6000 micrograms of oil (per gram) of wet mud. It contaminated also the local populations of</span> Uca pugnax. <span> Concentrations of oil that spilled greater than 1000 micrograms (ppm) were directly toxic to adults, 100 to 200 ppm, on the other hand, were toxic to juveniles, so how much more its effect to salt water marsh plants. They were not able to recover from toxins. </span>
Answer:
Plasmolysis occurs when a <u>plant </u>cell is inmersed in a <u>3X salt solution</u>.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
- <em>Plamolysis does not occur in </em><u><em>animal cells</em></u><em>.
</em>
- <u><em>Pure water </em></u><em>does not produce plasmolysis.</em>
