A long wavelength and low frequency sound creates what kind of pitch?
A long wavelength and low frequency sound creates a low pitch.
100
What type of weather does a low pressure system bring to an area?
Low pressure systems bring unstable stormy weather.
100
What is a comet?
A comet is a small body of ice with a long tail.
100
What is biodiversity?
Biodiversity is the variety of species. High biodiversity means having a large number of different species.
100
What does homozygous mean? Write an example.
Homozygous means the alleles for the gene are identical. Example: AA or aa
200
In a longitudinal wave, what direction is particle motion versus wave motion?
In a longitudinal wave, particle motion is parallel to wave motion.
200
What type of weather does a high pressure system bring to an area?
High pressure systems bring sunny, clear and stable weather.
200
What is the composition of the inner versus outer planets?
The inner planets are small, dense and rocky. The outer planets are large, less dense and gaseous.
200
What are two reasons for deforestation?
Deforestation is caused by cutting down trees for grazing land for livestock, planting crops, paper products
200
What does heterozygous mean? What is an example?
Heterozygous means the alleles for the genes are different. Example: Aa
300
In a transverse wave, what direction is particle motion versus wave motion?
In a transverse wave, particle motion is perpendicular to wave motion.
300
Which way does weather usually move? From low pressure to high pressure or high pressure to low pressure?
Weather systems usually flow from high pressure to low pressure.
300
Name the planets in order from the sun outward.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
300
What is the leading cause for extinction?
Habitat loss is the leading cause for extinction.
300
Create a punnett square to cross two homozygous recessive white plants. What is the genotype and phenotypes?
Genotype:4 bb Phenotype:4 white, 100% white
400
Draw a transverse wave and label -wavelength, crest and trough
See teacher diagram
400
What should you do during a tornado?
During a tornado you should get inside to a solid interior space without windows.
400
Draw a diagram of a lunar eclipse. Be sure to label the phase of the moon when this occurs.
Sun - Earth - Moon Full moon phase
400
What is global warming and what causes global warming?
Global warming is the increase in the earth's average temperature. Temperatures are rising because there are higher levels of greenhouse gases in the atmosphere.
400
What is the difference between dominant and recessive alleles?
Dominant alleles (R) are always expressed and mask recessive alleles (r) which are only expressed if there are two of them.
500
Draw a longitudinal wave and label - compression, rarefaction, wavelength
See teacher diagram
500
Why do we have weather on planet earth?
We have weather due to the uneven heating of earth's surface.
500
What is the difference between a spring and neap tide? During what moon phase do spring and neap tides occur?
A spring tide is when the difference between high and low tides are the greatest. Spring tides occur during the full and new moon phases. A neap tide is when there is the smallest difference between high and low tide levels. Neap tides occur during the first and third quarter phases.
500
Why is loss of biodiversity bad for an ecosystem?
Loss of biodiversity means a loss of species. This can make an ecosystem more likely to have a species go extinct.

Create a punnett square for a cross between a homozygous white rabbit and a heterozygous black rabbit. Include phenotype and genotype.
Genotype:2 Bb, 2 bb Phenotype: 2 black and 2 white
