DNA
What is a trait that helps an organism survive in its environment
adaptation
Name 2 biotic and abiotic factors in an ecosystem
Biotic- living
Abiotic- nonliving
What is a hypothesis
A testable prediction
What is Ms. Baumgardner's favorite color

What is the difference between dominant and recessive alleles
Dominant alleles are always expressed even if only one copy is present.
A recessive allele only shows up in the phenotype if two copies are present.
Name 2 of the 4 pieces of evidence that support the theory of evolution
Fossils
DNA
Comparative Anatomy
Embryology
What is the role of producers in an ecosystem
They make their own food through photosynthesis

Explain what natural selection is
The process where organisms with traits better suited to their environment tend to survive and reproduce more successfully, passing those traits to their offspring.
What is the difference between a food chain and a food web
Food chains show a single path of energy transfer, while a food web is a complex network of interconnected food chains
What type of graph is best for showing change over time
line graph
What is Ms. Baumgardner's favorite fast food
chick fil a
Explain how the structure of the cell membrane helps maintain homeostasis
selective permeability
Use a Punnett square to predict the ratio of offspring from two heterozygous parents (Bb x Bb)
BB- 25%
Bb 50%
bb- 25%
Describe how antibiotic resistance is an example of natural selection
Bacteria have mutated and developed defense mechanisms against antibiotic medication.
Explain how energy flows through a food web and why there is less energy at the top.
10% rule
A student claims that plants grow faster with music playing. They place one plant in a room with music and another in a silent room. What is the independent variable, and what data would you collect to support or refute the claim?
Independent variable: Whether music is playing or not.
Data to collect: Plant height over time, number of leaves, growth rate, or any other measurable growth indicator.
