Which transport requires energy in the form of ATP?
Which transport does not require energy?
Active Transport
Passive Transport
During transcription, which molecule carries the genetic information from DNA to the ribosome?
mRNA (messenger RNA)
What is the process where individuals with traits better suited to their environment survive and reproduce at higher rates?
Natural Selection
This diagram shows complex relationships between organisms in an ecosystem
Food web
Describe this genotype: AA
Homozygous Dominant
Active transport moves from a _________ to ___________ concentration gradient.
Passive transport moves from a _________ to ___________ concentration gradient.
low to high
high to low
Which organelle is responsible for assembling amino acids into a polypeptide chain during translation?
Ribosomes
A random change in allele frequencies, and it has the greatest effect on small populations is?
Genetic Drift
This cycle can be disrupted by increasing combustion of fossil fuels
Carbon Cycle
Heterozygous
Why must molecules pass through a protein channel in facilitated diffusion even though ATP is not needed.
Transporting larger molecules
What is the three-nucleotide sequence on mRNA that codes for a specific amino acid called?
Codon
This theory suggests that species evolve in rapid bursts, followed by long periods of little to no change.
Punctuated Equilibrium
These organisms are responsible for most of the disruptions that occur in the nitrogen and carbon cycle.
Humans
Homozygous
What are the reactants and products of Photosynthesis and Cellular Respiration?
Photosynthesis:
Reactants: CO2+H2O+SUNLIGHT Products: O2+C6H12O6
Cellular Respiration:
Reactants: O2+C6H12O6 Products: CO2+H2O+ATP
In eukaryotic cells, where does transcription occur, and where does translation take place?
Transcription-Nucleus
Translation- Cytoplasm(on ribosomes)
What is the term for structures in different species that have:
a similar function, different structure
a different function, same structure
no function
Analogous Structure
Homologous Structure
Vestigial Structure
Identify each symbiotic relationship:
One organism benefits, while the other is harmed
Both organisms benefit
One organism benefits, while the other is neither helped or harmed
Parasitism
Mutualism
Commensalism
The ratio of two heterozygous organisms in a dihybrid cross

Which cellular process removes carbon from the atmosphere and stores chemical energy in carbon compounds?
Cellular Respiration
Photosynthesis
