The unfertilized field in the above experiment represents what part of her experiment? | the control |
A group of individuals living together is referred to as a(n) | population |
Groups of similar cells that act as a functional unit are | tissue. |
While walking through a deciduous forest in New England one might observe squirrels, blue jays, gypsy moths, sugar maples, and blue spruce. All of those organisms represent a(n) | community |
A bacterial colony consists of identical cells that are derived from a single original cell. Those cells represent members of the same | species |
Over 300 breeds of purebred dogs exist today. They are the result of | artificial selection |

Which one of the following is not considered a kingdom of living organisms? | Chordata |
The highest level of complexity listed below is a(n) | ecosystem |
A group of species and the physical environment in which they live are called a(n) | ecosystem |
The original source of energy used by organisms is | the sun |
The energy-carrying molecule within the cell is | ATP |
In an experimental test, we attempt to manipulate only one factor at a time. This factor is called the | variable |

Biologists categorize all living things based on related characteristics into large groups called | kingdoms |
Living things can be distinguished from nonliving things because they have | cellular organization |
Living things are organized. What is the answer that illustrates this complexity, and is arranged from smallest to largest. | atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, species, community, ecosystem |
At each higher level in the hierarchy of living things, properties occur that were not present at the simpler levels. These properties are referred to as | emergent properties |
The five general biological themes include | evolution, energy flow, cooperation, structure determines function, and homeostasis. |
When you are trying to understand something new you begin by observation, and then put the observations together in a logical fashion to form a general principle. This method is called | inductive reasoning |
When trying to figure out explanations for observations, you usually construct a series of possible hypotheses. Then you make predictions of what will happen if each hypothesis is true, and | test each hypothesis, using appropriate controls, to rule out as many as possible. |
Which of the following statements is correct regarding a hypothesis? | After sufficient testing you can accept it as probable, being aware that it may be revised or rejected in the future. |
Cell theory states that | all living organisms consist of cells, and all cells come from other cells. |
The gene theory states that all the information that specifies what a cell is and what it does | is contained in a long molecule called DNA. |
