In cancer, the cells loose its ability to control
size
growth rate
surface area
chromosomes
What occurs in binary fission?
2 genetically identical cells are produced
a cell grows as large as they can
the nucleus of a cell disappears from the cell
the cell develops a double membrane
What is the purpose of spindle fibers in mitosis?
they help separate the chromosomes
they break down the nuclear membrane
they double the DNA
they make the chromosome visible
What are the phases of mitosis?
prophase, metaphase, anaphase, telophase
interphase, prophase, metaphase, anaphase, telophase
prophase, metaphase, anaphase, telophase, cytokinesis
prophase, anaphase, metaphase, cyokinesis
How are sexual reproduction and asexual reproduction different from each other?
sexual reproduction requires two parents and asexual reproduction requires only one parent
asexual reproduction requires two parents and sexual reproduction requires only one parent
genetic diversity is increased in asexual reproduction
asexual reproduction occurs only in multicellular organisms
Which phase is displayed?
prophase
anaphase
interphase
metaphase
Which phase is displayed?
interphase
prophase

Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes and event that results from mitosis but NOT meiosis?
two stages of cell division
replication of cellular genetic material
daughter cells that are identical to the parent cell
four daughter cells that are produced from each parent cell
Name this cellular process
mitosis
meiosis
cell cycle
cytokinesis
Which of the following best describes meiosis?
It is carried out in all tissues that require cell replacement
It occurs only in cells in the reproductive structures of organisms
It happens in all tissues except the brain and spinal cord
It is the first stage of mitosis.
The diagram below shows homologous chromosomes during prophase I of meiosis. Which of the following correctly describes the process being illustrated?
mutation in which the DNA content of the gene is altered
segregation of sister chromatids
condensation and segregation of alleles
crossing-over in which alleles are exchanged
