- What is likely to happen when a limited amount of enzyme is added to a reaction with an unlimited amount of substrate?
- Chloroplasts
- Organelles found in plant cells and eukaryotic algae that conduct photosynthesis
- Grana
- Stacked, disk-like plates embedded in the stroma (body) of the chloroplast which are the site of photosynthesis
- Transduction
- The process whereby a bacterium’s genetic makeup is altered when some genetic material is transferred from one bacterium to another via a viral bacteriophage
- Primary Oocyte
- These are present in reproductive organs at birth
- Secondary Spermatocytes

- The process of kin selection preserves⬦.
- Adaptive Radiation
- Process whereby one species can evolve into several new species over time as migration to new areas occurs and traits are specialized to fit new habitat
- Sympatric Speciation
- The development of members within a population that possess differences preventing successful reproduction with the original population
- Punctuated Equilibrium
- Short period of quick mutation and change resulting in new species

- Best-adapted individuals are most likely individuals to reproduce viable offspring
- Mutation
- Accidental change in genetic material
- Gene Migration
- The infiltration of a previously isolated group by a member of an adjacent population, resulting in the increase of genetic possibilities
