Crossing over begins to occur during - ANS ✔✔Prophase I
From prophase through metaphase of mitosis, each chromosome has _____ DNA molecules, while from
anaphase through telophase of mitosis, each chromosome has _____ DNA molecule(s). - ANS ✔✔two;
one
In diploid species, diploid cells may undergo either mitosis or meiosis. Haploid cells may undergo mitosis
(for certain species) but not meiosis because - ANS ✔✔homologous chromosomes cannot pair
The many blood vessels in elephants' ears help them cool their bodies by radiating heat. Which
statement about this radiated energy is accurate? - ANS ✔✔The original source of the energy was the
sun.
Of the events of a typical cell division listed below, which is most likely to occur third in an animal cell
that is going through mitosis? - ANS ✔✔The number of chromosomes in the cell doubles as double-
chromatid chromosomes are split into pairs of single-chromatid chromosomes.
Binary fission is more like animal cell division than plant cell division because - ANS ✔✔bacteria and
animals both pinch in to separate the cytoplasm into two pieces
If you were given a slide and told that the cells on it were performing cytokinesis, how would you tell if
you had plant cells or animal cells? - ANS ✔✔Look for a cell plate or a cleavage furrow.

metaphase, which checkpoint would not be passed until this was corrected? - ANS ✔✔M checkpoint
The mosquito Aedes aegypti has a karyotype of 2n = 6. Through independent assortment and
recombination, how many chromosomal combinations can be made during meiosis? - ANS ✔✔many
millions
How and at what stage is independent assortment accomplished? - ANS ✔✔metaphase alignment
