The failure of the attempt to reintroduce clapper rails in California was an example of the _____.
Lemur [1.5K]

The correct answer is option D, difficulty of redesigning workable ecosystems

Reason -

The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –

a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover

b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.

What happens during mitosiss?
Montano1993 [528]
Oh god, large question. My eyes hurt... Mitosis is the formation of 2 identical daughter cells (cell division). Mitosis have 5 phrases: interphase, prometaphase, prophase, metaphase, anaphase,  telophase and cytokinesis. The chromosomes are duplicated during the cell life just before mitosis since mitosis states that it is the splitting of the cells so duplicating the chromosomes isn't actually mitosis but it is still important to mitosis. Anyway, in interphase, the nucleolus starts to disappear, the microtubule starts to form and the chromosomes start to condense. In pro metaphase, some of the microtubule connect to the centromere, the cell membrane fully disappear and the chromosomes finishes condensing. In metaphase, the chromosomes are pulled to the center of the cell via by the contraction of the spindles and 2 spindles are connected to each of the kinetochores. In anaphase, the chromatids are separated via by the spindles. In Telophase, the nuclear membrane reappears, the chromosomes un-condenses and the micro tubal breaks down. In Cytokinesis, the cell membrane in one cell breaks apart from the other cell forming 2 daughter cells or in plant cells, another cell wall is formed. (this process can differ fro each different organism)
