A single celled protist undergoes reproduction resulting in two identical cells. Is this an example of sexual reproduction or asexual reproduction?
Asexual
Is sexual or asexual reproduction more beneficial in a changing environment?
Sexual
Why is sexual reproduction more beneficial in a changing environment?
It results in more genetic diversity.
True or false: Meiosis produces four genetically different cells and mitosis produces two genetically identical cells.
true
What is the process that splits the cytoplasm into two different cells?
Cytokinesis
What is the benefit of crossing over?
Genetic variation increases
Does the following statement describe mitosis or meiosis? The chromosomes separate and the nucleus divides to create two new genetically identical daughter cells.
Mitosis
State the order of the phases of mitosis.
Prophase, metaphase, anaphase, telophase
State the order of the phases of meiosis.
Prophase 1, metaphase 1, anaphase 1, telophase 1, prophase 2, metaphase 2, anaphase 2, telophase 2
In what phase does the cell rest, grow, and replicate its DNA?
Interphase
At what stage of mitosis do the chromosomes line up in the middle of the cell?
Metaphase
In which phase of meiosis to the homologous pairs line up in the middle of the cell?
Metaphase 1
In what phase of mitosis do the nuclei of the new cells start to grow around the divided chromosomes?
Telophase
In what phase of meiosis does the nuclear envelope disappear and the chromosomes condense to become more visable?
Prophase 1
In what phase of mitosis do the spindle fibers pull the chromosomes apart by the centromeres?
Anaphase
In what phase of meiosis do the spindle fibers pull the homologous pairs apart?
Anaphase 1
