Mitosis 1
Phase of mitosis where sister chromatids separate
Anaphase
Order the stages of mitosis in sequence
prophase, metaphase, anaphase, telophase
State what happens in anaphase 1 of meiosis.
homologous chromosome pairs separate to opposite sides of the cell
Number of daughter cells at the end of meiosis
4 daughter cells
The greenhouse effect helps with ______
maintaining Earth's surface temperature
Structure responsible for pulling sister chromatids apart.
State the difference between an animal cell going through cytokinesis compared to a plant cell.
During cytokinesis in a plant cell, a cell plate forms between cells eventually becoming the cell wall.
The number of daughter cells resulted after meiosis 1 is
2 daughter cells
A homozygous white flower (WW) crosses with a pink flower (WR). What's the probability of the offspring being pink?
1/2
What are Earth's three main climate zones?
polar zone, temperate zone, tropical zone
Mitosis is most directly involved in which of the following processes?
C) Tissue Repair
Define a pluripotent cell
A cell which is able to differentiate into most or all cell types but not a new organism.
What is a tetrad?
A pair of homologous pair formed during crossing over.
Pattern of inheritance do both alleles contribute equally to the phenotype.
Codominance
Three parts of ATP molecules are?
adenine, ribose, and three phosphate groups
The p53 gene is responsible for
regulating the cell cycle
State the difference between embryonic stem cells and adult stem cells.
Embryonic stem cells come from embryos and are pluripotent, whereas adult stem cells come from adults and are only multipotent.
What is synapsis?
Pairing of homologous chromosomes.
What happens in crossing over and why is it significant?
During crossing over, homologous chromosomes exchange genetic material during prophase I of meiosis. This process increases genetic variation among gametes, as it results in new combinations of alleles, contributing to the genetic diversity of offspring.
What is the endosymbiotic theory?
Some of the organelles inside a eukaryote were once prokaryotes that "live" inside of the eukaryotes.
A cell that has 5 chromosomes in the G1 phase will have ____________________ chromatids in the G2 phase.

Name the two types of tumors. Define them.
Benign : non-cancerous tumor
Malignant : cancerous tumor
A man with type AB blood marries a woman with type O blood. Which blood type is impossible for their children to have?
Type AB
There's a cross between Bbrr x BbRr. What's the probability that the offspring will be homozygous recessive for both genes?
2/16
Explain the role of electron carriers in photosynthesis and give one example.
Electron carriers accept pairs of high-energy electrons and transfer them, along with their energy, to other molecules. NADP+ is one example of an electron carrier.
