100
in which step of mitosis is the DNA of a cell copied
interphase
100
what movement happens with a hypotonic solution
water goes in
100
how do cells help regulation
They filter the good things through the body and get rid of the bad things
100
There is less solute and more water than another solution
What is a hypotonic solution
200
what is the purpose of mitosis
to replace old cells
200
what movement happens with a isotonic solution
water goes both in and out
200
in mitosis,the step, interphase, creates what
two identical full sets of chromosomes
200
in which step of mitosis do the chromosomes attach to the spindle fibers
metaphase
200
in which step of mitosis do the chromosomes go into an X shape
prophase
300
How do cells help organisms repair
through cell division, more cells are made to heal a wound
300
in which step of mitosis are the sister chromitads pulled apart to opposite poles
anaphase
300
There is an equal amount of solute and water when compared to another solution
isotonic solution
300
what movement happens with a hypertonic solution
water goes out
300
during telophase, in mitosis, a membrane forms around the chromosomes to create new what
nuclei
400
what is the result of mitosis
there are a full set of chromosomes (telophase)
400
there is more solute and less water than another solution
hypertonic solution
400
how does the cell membrane maintain homeostasis
controls which substances go in and out of the cell
400
How do cells help in reproduction
through mitosis, over a long span of time, more and more cells are duplicated to create another individual organism
400
when a single cell divides and is formed into two identical daughter cells
mitosis
500
what are all five phases of mitosis called
interphase, prophase, metaphase, anaphase, telophase
500
the membrane around the nucleus dissolves, releasing the chromosomes, in which part of mitosis
prophase
500
During anaphase what pulls apart the sister chromatids
mitotic spindle
500
how do cells help an organism grow
The more cells a body contains, the larger the person. Through cell division, more cells are made
500
during metaphase it is imparitive that the chromosomes are ____ in the center of the ______
lined up, cell
