Binary fission is
division of one cell into 4
division of a prokaryotic cell
division of a eukaryotic cell
the duplication of DNA
Autosomes are
found in all prokaryotic cells
found in all somatic cells
are found in eukaryotic cells
are found in body cells

Binary fission allows for genetic variation
True
False
not sure
Parthenogenesis can allow for genetic variation in
only male bees
only female bees
no bees
only the queen bee
Binary fission takes a short time because
prokaryotic cells are small
prokaryotic cells undergo mitosis
prokaryotic cells need to divide the nucleus
prokaryotic cells are abundant
Asexual reproduction is advantageous because it
allows genetic variation of a organism
allows gametes will be all different
allows fast reproduction
allows for sister chromatids to cross over
Asexual reproduction is disadvantageous because
of no genetic diversity in the organism
every cell is different
each of the chromatids are different
binary fission can affect the nucleus
Interphase is
the stage after metaphase
the stage that is the longest in the cell cycle
the stage that forms a cell plate
the stage that centrioles attach to the centromere
A Tetrad is made up of two
sister chromatids
sister chromatin
pairs of sister chromosomes
pairs of sister chromatids
At the end of meiosis I, there are
4 diploid cells
2 haploid cells
2 diploid cells
4 haploid cells
In the process of meiosis the odd one out is
crossing over in Prophase I
sister chromatids being pulled apart at Anaphase II
independent assortment of chromatids
genetically identical chromatids in telophase
The amount of DNA found in a cell that has undergone S phase of a human is
same amount
half the amount
twice the amount
quarter the amount
Necrosis is
programmed cell death
random death of many cells
random death of one specific cell
found only in gametes
Totipotent cells can be found in the
liver
heart
fetus
embryo
Multipotent cells can be found in
gametes
brain
bone marrow
fetus
Gonads are the human storage facility of
male and female sex cells
male sex cells only
female sex cells only
somatic cells only
A fertilised egg cell forms a fetus. The cells of the fetus will divide via what process
mitosis
binary fission
apoptosis
meiosis
