Vocabulary 1
Groups of individual organisms which are very similar
What is species?
An amoeba is unicellular.
What is made up of one or more units called cells?
Series of steps designed to help solve problems and answer questions.
Become separate species because enough genetic differences accumulate to form big changes
What is genetic divergence?
Written as genus then species always in Latin and italicized.
What is a scientific name?
Barriers that prevent reproduction by preventing mating or prevent the development of fertilized egg
What is reproductive barrier?
When a human steps out into cold air the body shivers to maintain it's temperature at 98.6.
What is maintains homeostasis?
Skill a scientist is using when she listens to the sounds whales make.
What is observation?
New species evolves from ancestral species while both living in same geographical area
What is sympatric speciation?
Scientists use this most often today to classify living things.
What is DNA?
Process by which a species splits into 2 or more new species due to geographic isolation.
What is allopatric speciation?
Green plants produce their own food through photosynthesis
What is obtain and use energy?
For an experiment to be accepted as true and published it must go through this process.
What is peer review?
Groups of organisms similar enough to interbreed and produce fertile offspring under natural conditions.
What biological species
List the 7 classifications. Must be in order from largest to smallest.
What are Kingdom, Phylum, Class, Order, Family, Genus, Species?
Rate of evolution to be slow and constant, with small changes accumulating to form big changes
What is gradualism?
A tulip opens up in the morning at sunrise and closes up in the evening at sunset.
What is respond to environment?
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. Give the dependent variable.
What are the number of plants in the water?
Species diverge in bursts of relatively rapid change, and then remain stable for relatively long periods
What is punctuated equilibrium?
List the 6 kingdoms.
What are Archeabacteria, Eubacteria, Protista, Fungi, Plantae, Animalia?
Limits gene flow which would tend to maintain uniformity between the two populations. Physical separation by a barrier limits migration and prevents interbreeding.
What is isolation?
You no longer need your wisdom teeth or appendix.
What is adaptation/evolve over time?
A scientist who wants to study the affects of fertilizer on plants sets up an experiment. Plant A gets no fertilizer, plant B gets 5mg of fertilizer each day, and plant C gets 10mg of fertilizer each day. Name the control group.
What is plant A?
Inability of a species to breed successfully with related species due to geographical, behavioral, physiological, or genetic barriers.
What is reproductive isolation?
List the hierarchy of biological organization. There are 15. List in order from smallest to largest.
What are atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism, population, community, biome, ecosystem, biosphere?
