100
This organelle houses the DNA and is considered the "brain" of the cell.
What is the nucleus?
100
Any change in DNA results in one.
What is a mutation?
100
The genetic makeup of an organism.
What is the genotype?
100
Some organisms have traits that help them survive and reproduce. Over time these traits become more common in a population.
What is natural selection?
100
Two organisms in a close relationship, where one organism is helped, but the other organism is harmed.
What is parasitism?
200
This kind of organism has free floating DNA, is unicellular, and does not have specialized organelles.
What is a prokaryote?
200
The genetic code can be found here.
What is the sequence of nitrogenous bases?
200
Observable characteristics of an organism that are determined by genes.
What is Phenotype?
200
These parts of animals are similar in structure, but may serve different functions.
What are homologous structures?
200
Plants make up this foundational level of a food chain, energy pyramid, or food web because they are autotrophs.
What are producers?
300
This kind of organism may be unicellular or multicellular, has a membrane-bound nucleus, and has other specialized organelles.
What are eukaryotes?
300
These are the three parts that make up a DNA nucleotide.
What is sugar, phosphate, and nitrogenous base?
300
In this type of dominance, neither trait is dominant and both traits are seen.
What is codominance?
300
These structures are reduced in size and/or function but show ancestry.
What are vestigial structures?
300
Most energy is used up or lost at each trophic level, leaving only this percentage available to the next level of consumers.
What is 10%?
400
This organelle is found in plant cells and is the site of photosynthesis.
What is a chloroplast?
400
This is the kind of sugar that is found in a DNA molecule.
What is deoxyribose?
400
In this type of dominance, neither trait is dominant and a blend of traits is produced.
What is Incomplete dominance?
400
The movement or transfer of genetic material from one population to another.
What is gene flow?
400
Several interconnected food chains make up one of these.
What is a food web?
500
This organelle is found in plant, animal, and fungal cells and is where cells break sugar down to produce energy for cellular processes.
What is the mitochondria?
500
DNA codes for these.
What are proteins?
500
Curly hair (H) is always dominant to straight hair (h). The ability to taste PTC (P) is always dominant to being unable to taste PTC (p). If both parents are heterozygous for both traits, what would be the genotype of an offspring with straight hair and the ability to taste PTC?
hhPp
500
A small group of individuals starts a new population, resulting in less genetic diversity in the new population.
What is the founder effect?
500
The strangler fig is a vine that starts out as a seed in the tree canopy of the rainforest. It drops its roots down from the canopy to the forest floor.
By sprouting in the rainforest canopy, the strangler fig seedling is exposed to more of this.
What is sunlight?
