Ecology & Biomes (Ch. 9)
This is the long-term pattern of weather in a region.
Climate
This term describes all living and nonliving things interacting in one area.
Ecosystem
DNA stands for this.
Deoxyribonucleic acid
A change in DNA sequence is called this.
Mutation
A group whose members can interbreed and produce fertile offspring is called this.
Species
These two abiotic factors most strongly determine terrestrial biomes.
Temperature and Precipitation
Clearing forests permanently for agriculture or development is called this.
Deforestation
These are the four nitrogenous bases of DNA
Adenine, thymine, cytosine, and guanine
This process is the only one that leads to better adaptation to environment.
What is natural selection?
The process by which new species form is called this.
Speciation
This biome is cold, treeless, and contains permafrost.
Tundra
This harmful process happens when too many nutrients enter water, reducing oxygen.
Eutrophication
A pairs with this, and C pairs with this.
Thymine and Guanine
These are the three types of small-scale mutations.
Substitution, Insertion, and Deletion
A horse and donkey produce this sterile hybrid
Mule
This side of a mountain receives less rainfall because of rain shadow effect.
Leeward side
This type of species can dramatically affect an ecosystem if removed.
This organelle reads mRNA codons to build proteins.
Ribosome
This type of mutation shifts the reading frame of codons.
What is a frameshift mutation?
Speciation caused by geographic isolation is called this.
Allopatric speciation
Name the five major biome categories.
Aquatic, grassland, forest, desert, and tundra
This farming practice grows only one crop and reduces genetic diversity.
Monoculture
This process uses the order of DNA bases to produce a chain of amino acids that becomes a protein.
Protein Synthesis
Name the five ways gene pools can change.
Population size, non-random mating, mutation, gene flow, and natural selection
Speciation caused by behavioral or timing differences without geographic separation is called this.
sympatric speciation
