What is likely to happen when a limited amount of enzyme is added to a reaction with an unlimited amount of substrate?
Organelles found in plant cells and eukaryotic algae that conduct photosynthesis
Stacked, disk-like plates embedded in the stroma (body) of the chloroplast which are the site of photosynthesis
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
Haploid cells that will develop into male gametes

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
Kin Selection
The tendency for an individual to express altruistic traits toward close relatives, thus preserving the genes that produce altruistic traits

when the water pressure is equal inside and outside the cell it is said to be…
Differential Reproduction
Best-adapted individuals are most likely individuals to reproduce viable offspring
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
Hardy-Weinberg Equilibrium
This states that in a population that is in equilibrium with its environment, gene frequencies and genotype ratios remain constant
