Researchers have determined that the chemical colchicine 1 point
stops cell division by preventing the formation of spindle
fibers. Without these fibers, the sister chromatids cannot
separate properly into the daughter cells during anaphase, and
cytokinesis cannot occur. However, the cell may continue to
make copies of its chromosomes. As a result, the nucleus of
the cell contains multiple sets of chromosomes, a condition
called polyploidy. Which of the following statements can be
supported by the evidence in the text? *
The nucleus is unable to reform during telophase of mitosis.
Cells treated with colchicine may have half as much DNA as the parent
cell.
Colchicine affects the number of cells that are able to go through
interphase.
Cells treated with colchicine may have 2 or more times as much DNA
as a parent cell.

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.
