All living things have cells: List two main differences in structure between an animal and a plant cell
Answers may vary
- Animal cells tend to be more circular; plant cells more square/rectangular
- Plant cells have a cell wall in addition to a cell membrane; animal cells only contain a cell membrane
- Plant cells have a large central vacuole to hold liquid; animal cells have several small vacuoles
- Only plant cells have a chloroplast, which helps them to create energy using sunlight; animal cells do not contain this

Ms. Diaz is looking to grow more purple flowers in her classroom garden. She wants to cross-pollinate two plants; Plant A has the genotype Pp for purple flowers, and Plant B has the genotype pp for white flowers.
Which plant's genotype would be considered to be heterozygous?
Plant A because each allele is different (dominant and recessive)

For full credit:
- Identify one geologic process or event that must have happened
- identify evidence to support your answer
Answers will vary
- Magma must have pushed up into the layers after the layers formed. There is an inclusion that cuts through several layers
- A tectonic shift/earthquake must have happened after the layers were formed. There is a fault line that cuts through the layers; we can see similar layers on both sides that are at different heights on either side of the fault
- Igneous rock was formed. Magma pushed its way up through the rock layers and cooled to form an igneous rock inclusion
- Erosion happened. The rock faces on either side of the fault are rounded and smoothed away

Kailey wanted to perform an investigation. She placed baking soda (2NaHCO3) on a plate and baked it in the oven at 400 degrees F for 15 min. Only a solid substance remained on the plate
2NaHCO3 --> Na2CO3 + CO2 + H2O
baking soda --> sodium carbonate + carbon dioxide + water
Kailey claimed the total mass would not change when heated in the oven. Why is this claim false?
The oven is not a closed system, the gas (Carbon Dioxide) is able to escape the oven
