Scientists hypothesize that the first life forms on Earth
1. were multicellular organisms.
2. lived on land.
3. did not need oxygen to survive.
4. resembeled today's plants.
Which of the following was true about the experiment conducted by Miller and Urey?

What is taxonomy?
1. the scientific study of how living things are classified
2. the name of Aristotle's classification system
3. the process used by geologists to classify rocks
4. the process of observing an organism's behavior
Why do scientists organize living things into groups?
1. so they can find them in the wild more easily
2. so that the organisms are easier to study
3. so they can make sense of the variety of rocks on Earth
4. so products from living things can be easily found in groceries
What is binomial nomenclature?
1. classifying organisms into seven levels
2. the naming system developed by Aristotle
3. grouping animals based on how they move
4. a naming system in which each organism is given a two-part name
An organism's scientific name consists of
1. its class name and its family name.
2. its kingdom name and its phylum name.
3. its genus name and its species name.
4. its phylum name and its species name.
Which is the broadest classification level?
1. family
2. kingdom
3. phylum
4. species
The more classification levels that two organisms share,
1. the closer together on Earth they live.
2. the easier it is to tell them apart.
3. the more characteristics they have in common.
4. the more distantly related they are.
What is one way in which scientists get information about the evolutionary history of species?
1. by comparing organisms' body structures
2. by observing where organisms live
3. by observing what organisms eat
4. by studying how organisms move
The gradual change in species over time is called
1. taxonomy
2. homeostasis
3. evolution
4. classification
One characteristic used to place organisms into kingdoms is
1. how they move.
2. where they live.
3. their ability to make food.
4. their ability to reproduce.
Which kingdom includes only multicellular heterotrophs?
1. protists
2. archaebacteria
3. plants
4. animals
The process of change that occurs during an organism's life to produce a more complex organism is called
1. reproduction.
2. growth.
3. development.
4. stimulus.
Which is the most abundant chemical found in living cells?
1. water
2. carbohydrates
3. proteins
4. nucleic acids
The experiments of Redi and Pasteur helped to demonstrate that
1. species gradually change over time.
2. living things do not arise from nonliving material.
3. organisms can be placed in groups based on their similarities.
4. the chemicals of life could have arisen on early Eart.
Which classification level is broader than the phylum level?
1. order
2. class
3. family
4. kingdom
A plant growing toward light is an example of
1. reproduction.
2. a response.
3. a stimulus.
4. development.
The mistaken idea that living things arise from nonliving sources is known as
1. binomial nomenclature.
2. spotaneous generation.
3. reproduction.
4. homeostasis.
What contribution of Charles Darwin had a major impact on classification?
1. binomial nomenclature
2. taxonomy
3. seven levels of classification
4. his theory of evolution
The source of energy for most autotrophs is
1. water.
2. the sun.
3. heterotrophs.
4. other autotrophs.
Which kingdom includes only prokaryotes?
1. archaebacteria
2. protists
3. plants
4. fungi
Which of the following characteristics do all plants share?
1. being unicellular
2. producing flowers
3. being a prokaryote
4. being an autotroph
Which of the following kingdoms includes both unicellular and multicellular organisms?
1. eubacteria
2. protists
3. plants
4. archaebacteria
An organism that makes its own food is called a(n)
1. heterotrph
