I would go for the first or the third good luck!!!
Answer:
More than two complete sets of the chromosomes (polyploidy).
Explanation:
Assembly of spindle microtubules assist the chromosomes to arrange in the equator of the cell during metaphase. This is followed by the splitting of centromere and segregation of sister chromatids towards the opposite poles of the cell to ensure equal distribution of chromosomes among the daughter cells.
Any drug that prevents the assembly of the spindle apparatus would not allow the alignment of the chromosomes in the cell's equator. This would prevent the anaphasic segregation of daughter chromosomes to the opposite poles.
Some of the resulting daughter cells are most likely to have more than two sets of chromosomes.
Reproductive isolation. Species refer to the group of organisms which share common morphological features and can interbreed and produce a viable offspring. Thus, the organisms of one species are reproductively isolated from the organisms of other species
Answer:
Due to over-pumping of water.
Explanation:
The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.
