Within cells, structures called chromosomes contain genetic material in the form of ____. | DNA p.6 |

A(n) _____ is an organism that uses energy, usually in the form of sunlight, to build food molecules that store energy for later use. | producer p.8 |
A(n) _____ is an organism that obtains its energy by feeding on other organisms or their remains. | consumer p.8 |
* In contrast to energy, which flows through an ecosystem in ____ direction, chemicals ____ within an ecosystem. | one, cycle p.8 |
By burning fossil fuels, humans have increased the levels of _____ in the atmosphere, which is a molecule that traps heat and has lead to global warming. | carbon dioxide p.8 |
____ is a process of biological change in which species accumulate differences from their ancestors as they adapt to different environments over time. | Evolution p.9 |
* Evolution accounts for both the ____ and ____ of life. | unity, diversity p.9 |
* TRUE or FALSE: All organisms on this planet share the same genetic code. | TRUE (The genetic code is the code that is used to translate the order of nucleotides within DNA into the sequence of amino acids needed to make a particular protein. DNA from a human can be inserted into any organism on this planet, and that organism will make the same proteins that would be made by the human. You will learn more about this when we study genetic engineering later in the year.) p. 11 |
The mechanism that Darwin proposed to explain what causes evolution is ______. | natural selection p.12 |
Scientists use a process of inquiry that includes making observations, then forming logical explanations for their observations called ________ that they then test. | hypotheses p.13 |
Biology, like other sciences, begins with ______. | making observations p.13 |

* Data that is recorded as a numerical measurement is called ____ data. | quantitative p.14 |
* The practice of making generalized conclusions from a large set of specific observations is called _____ reasoning. | inductive p.14 (In deductive reasoning, you take a broad generalization and make specific predictions based on it. In inductive reasoning, you do the opposite. You take a number of specific smaller observations and make a larger generalized conclusion based on them) |
* The testable predictions that can be made based on a particular hypothesis would be an example of _____ reasoning. | deductive p.14 (In deductive reasoning, you take a broad generalization and make specific predictions based on it. In inductive reasoning, you do the opposite. You take a number of specific smaller observations and make a larger generalized conclusion based on them) |
