Mechanisms of Evolution
Process where organisms with adaptations tend to survive and produce more offspring
What is natural selection?
Similar embryonic stages suggest these organisms share this
What is a common ancestor?
The main purpose of leaves
What is photosynthesis?
The process that occurs in the mitochondria
What is cellular respiration?
An organism that creates its own food
What is an autotroph?
The change in allele frequencies due to random chance
What is genetic drift?
The trend in brain size in human evolution
What increases?
The main purpose of a flower
What is reproduction?
C6H12O6 + 6O2 → 6CO2 + 6H2O
What is the equation for cellular respiration?
An organism that cannot make their own food
What is a heterotroph?
Conditions of this mechanism include overproduction of offspring, struggle to survive, and inherited variation
What is natural selection?
Similar structures, but different functions in species sharing a common ancestor
What are homologous structures?
The main purpose is to transport water in a plant
What is the xylem?
6CO2 + 6H2O → C6H12O6 + 6O2
What is the equation for photosynthesis?
The loss of water vapor through the stomata
What is transpiration?
Exchange of genes with another population due to migration between populations
What is gene flow?
Similar functions, but different structure in species that independently evolved.
What are analogous structures?
This molecule goes into the stomata
What is the CO2?
The process which cells can break down sugars to generate energy in the absence of oxygen.
What is anaerobic respiration?
The mode of nutrition for plants
What are autotrophs?
Gene flow increases variation by introducing these into a population
What are alleles?
remnants of structures that have once had important functions, but have no purpose in modern descendants, suggesting a common ancestor
What are vestigial structures?
This type of plant tissue transports substances
What is vascular tissue?
The part of an ATP molecule when removed, releases energy to make ADP
What is a phosphate group?
The mode of nutrition for fungi
What are heterotrophs?
