The nitrogen containing amino group is recycled while the remainder of the molecule is excreted in the urine
Trees are very important natural resources. They are the source of food, shelter and habitat. We get various woods, timber , fodder from the forest. Trees hold the soil firmly. Forests helps in conducting water cycle. If trees are cut down then environmental pollution will increase because trees purify the Air. Land pollution , air pollution , water pollution may increase. Biodiversity can be affected.
<span>True. Plants get their energy from the sun, and we get ours from plants and animals in which they all live in environment. </span>
In cell biology, mitosis (/maɪˈtoʊsɪs/) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division. In general, mitosis is preceded by S phase of interphase (during which DNA replication occurs) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically identical to each other. So yes i would put A-Mitosis
Closed intranuclear pleuromitosis is typical of Foraminifera, some Prasinomonadida, some Kinetoplastida, the Oxymonadida, the Haplosporidia, many fungi ( chytrids, oomycetes, zygomycetes, ascomycetes ), and some Radiolaria ( Spumellaria and Acantharia ...
Closed extranuclear pleuromitosis occurs in Trichomonadida and Dinoflagellata.
Closed orthomitosis is found among diatoms, ciliates, some Microsporidia, unicellular yeasts and some multicellular fungi.
Semiopen pleuromitosis is typical of most Apicomplexa.
Semiopen orthomitosis occurs with different variants in some amoebae ( Lobosa) and some green flagellates (e.g., Raphidophyta or Volvox ).
