Cells Cells
The purpose of cell division
What is to grow, repair and reproduce cells?
Bonus 1000 points: Sing the 1st verse of Cells Cells are .........
What factors can cause one variation to be more beneficial than another?
Traits that improve survival or reproduction.
What is the law of superposition?
in an undisturbed sequence of sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is on top. Each layer is younger than the one below and older than the one above
Harry Potter was always told that he had his mother’s blue eyes. This is a recessive trait (bb).
Harry’s dad was heterozygous for his brown eyes (Bb). What were Harry's chances to get his mother’s blue eyes?
50%
Bonus 500 points: What are the percentages of genotype and phenotype?
What causes an earthquake?
A sudden release of energy along faults or tectonic plate boundaires.
Describe the difference between Mitosis and Meiosis
What is mitosis produces 2 identical cells for growth and repair and meiosis creates 4 genetically different cells?
Bonus 400 points: What does "fitness" mean in terms of natural selection?
Which period is known as the "Age of Reptiles"?
Jurassic
Explain the difference between dominant and recessive alleles.
A dominant trait is one that is expressed even when only one copy of the gene is present, while a recessive trait is expressed only when two copies of the gene are present
The San Andreas Fault is what type of fault?
Transform or Strike slip fault
Bonus 400 points: Quote 4 lines from the Minecraft movie
Tumor production, extra chromosomes and/or cell death occurs because of this.
What happens if cells do not divide correctly?
Why is genetic variation important to evolution?
When a population has diverse genetic makeup, some individuals will have traits that are better suited to the environment, giving them a higher chance of survival and reproduction.
What is the current geological period called?
Quaternary
Bonus 300 points: Do the chicken banana dance
The physical trait that one sees in the offspring.
Phenotype
Bonus 500 points: Name at least 5 summer songs
What type of medium can S waves travel through?
Solids
Why is meiosis important for sexual reproduction?
It ensures that gametes (sperm and egg cells) have half the number of chromosomes as the parent cell.
How does the environment affect natural selection?
The environment drives natural selection. It determines which traits will be beneficial or harmful to an animal. Beneficial traits will be passed on to the next generation, while harmful traits will be eliminated.
What is the longest division of geologic time?
Eon
Bonus 200 points: How many hours until summer?
A possible form a trait may have that we represent with a letter.
Allele
Destruction, loss of life, landslides, or tsunamis
Why are chromosomes an important part of cell division?
they ensure accurate replication and equal distribution of DNA, guaranteeing that each new cell receives the correct genetic material
How do fossils support the theory of evolution?
What makes a fossil a good index fossil?
1. It is widely found
2. From a short period of time
3. Easily recognizable
Patrick met Patti at the dance. Both of them are heterozygous for their pink body color, which is dominant over a yellow body color. Create a Punnett square to show the possibilities that would result if Patrick and Patti had children.
Draw the Punnett Square on the white board.

What are the 3 types of volcanoes and explain the differences?
