But in a urine drug test, the use of cannabis is detectavlâ¦e for periods of up to one month. I like to dilute my pee with warm sink water and I excercise like crazy before a drug test.
Mitosis in Unicellular Organisms. In unicelullar (single-celled) organisms, mitosis is a common and important form of asexual reproduction. It can also be called binary fission, and plays a role in a similar process called multiple fission.Organisms that reproduce through mitosis make exact copies of themselves.n unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.
15. Do algae reproduce sexually or asexually? Some algae reproduce sexually and others reproduce asexually. In unicellular algae, reproduction is generally asexual and is carried out via binary division. In pluricellular algae, asexual reproduction can occur via fragmentation or sporulation. In the sexual reproduction of algae, uni or pluricellular, the fusion of gametes (syngamy) occurs. In some algae, all cells can become gametes and in others only some cells can be used in that way. Some species may present the alternation of generations, forming gametophytes and sporophytes with different ploidies.
