Vocab.
Population
All of the same species are living in a particular area.
______ and/or _________ _______ - if two spieces share lots of physical similarities, they are probably related.
Fossils and comparative anatomy
Natural selection
Organisms that are best adapted for their environment have the highest fitness and will therefore survive, reproduce, and pass their good genes to their offspring.
Segment of DNA that codes for a particular protein long chains of amino acids.
Gene
Nucleus
Comntians DNA in eukaryotes
Community
All of the living things (all species) living in a particular area.
______ - compare DNA, RNA, or amino acids (proteins). If the molecules have few differences, then they are probably related.
Biomolecule
Sexual Selection
Females choose males based on "sexy" or "showy phenotypes or behaviors.
Different forms of a gene.
Alleles
Cell Membrane
Controls what enters and leaves the cell.
Ecosystem
Community of living things plus their non-living surroundings.
Every enzyme help one reaction and binds to one ___ (starting material).
Substrate
Gene Flow
When individuals move into or out of a population, new alleles/genes/traits are added to (or removed from) the mating gene pool.
Genotype
Cell Wall
Extra support/protection around the plant and bacteria cells
Algal blooms
Extra fertilizer washes into lakes or ponds; algae takes up extra nutrients and overpopulates; algae start dying off, and decomposers increase in number and stuck all the oxygen out of the water.
Shape is very importent. If the shape changes, enzyme is ___ and can't bind to substrate.
Denatured
Genetic Draft
Random change in gene frequency within a population due to ramdom events.
Physical trait determined by genotype.
Phenotype
Ribosomes
Make proteins
Carrying capacity
The number of organisms in a population that the ecosystem can support.
Occurs in _______ - contain green pigment______.
Chloroplasts, Chlorophyll
Enzymes are what?
Special types of proteins that catalyze (speed up) chemical reactions in living things.
Diagram used to predict genotype and phenotype ratios or offspring.
Punnett Square
Mitochondria
Brack down glucose to release energy for the cell to use.
