This organelle functions as the "brain" of the cell, containing DNA and controlling cellular functions.
The nucleus
The lungs are one of the main organs of this body system.
Respiratory system
One strand of DNA has the sequence ATCG. What would the sequence of its complimentary strand be?
TAGC
This term describes when humans intentionally allow certain plants/animals to reproduce instead of others in order to get desired traits.
Artificial selection (or selective breeding!)
This type of evidence of changes in life typically involves discussing rock layers.
Fossil evidence
Cellular respiration takes place in this organelle.
Mitochondria
This system moves blood to all the body's cells/tissues/organs
Circulatory (or cardiovascular) system.
Humans have 46 of these, and receive 23 from each parent.
Chromosomes
List one of the two ways in which genetic variation can be introduced to a population (two possible answers, only need 1!)
Mutation OR sexual reproduction
These three traits are shared between all vertebrate embryos (must list all 3!)
Gill slits, eyes, tails
This organelle is described as "selectively permeable," allowing certain substances to enter the cell but not others.
Cell membrane
This level of organization is one size larger than cells
Tissues
If two heterozygotes have offspring, what is the percent chance this child will also be heterozygous for that trait?
50%
This term describes the use of genetic technology to cure or treat a disease
Gene therapy
This is a tool that models how closely related modern species are, based upon shared traits
Cladogram
These two organelles are found only in plant, and not animal, cells.
Cell wall and chloroplasts
These two body systems would work together to provide (get into the body) the necessary molecules in order to create energy for the body
Digestive and respiratory systems
This type of genotype would include both a dominant and recessive allele
Heterozygous
This word describes a trait that helps an organism survive in a given environment
Adaptation

Consider this fossil record. Which of the organisms could be an ancestor from which organism B is descended? Must list all possible ancestors!
Organism C, A, and D.
These organelles assemble amino acids in the proper order in order to make new proteins.
Ribosomes
This type of cell carries messages from the brain to the body
Motor nerves
This type of inheritance results in mixed phenotypes that have characteristics of two different traits at the same time (for example; a flower with red and white spots)
Codominance
A farmer is planting crops. A billboard is built over the farmer's crops, shading them. This causes the crops to eventually develop adaptations to growing in low light, since only these plants are able to survive. What word describes this phenomenon?
Natural Selection
This type of evolution describes two species becoming more similar/developing the same trait.
Convergent evolution
