Morning! I just need some help with this question! Ex. If it is A and it is mitosis then you would put A-Mitosis
polet [3.4K]

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 ).

Why is a system’s work output limited?
netineya [11]
<span>The correct answer is Energy is lost as heat in each stage, causing the amount of energy available to decrease with each stage. This means that eventually energy is bound to run out. Simplest example is a car for example, as long as it works there's less and less fuel, and eventually the energy runs out, or in this case the fuel.</span>
