share with a partner turn to a partner and compare your lists. if you have some of the same terms highlighted or circled, discuss the definitions with your partner. are they the same? if not, work with each other and a reference source, such as a dictionary, to resolve any disagreements.
draw a picture choose two familiar vocabulary terms and use the space on this page to draw a picture of each. label each drawing with the vocabulary term it illustrates.

Explanation:

Below are clear, standard definitions for each term, followed by example drawings for two selected terms:

1. species: A group of organisms that can interbreed to produce fertile offspring.
2. adaptation: A trait that helps an organism survive/reproduce in its environment.
3. natural selection: Process where organisms with favorable traits survive and reproduce more.
4. suppression: Limiting or stopping a biological process or trait.
5. fossil record: The collection of all preserved fossils, showing past life.
6. chronological: Arranged in the order of time events occurred.
7. extinction: When all members of a species die out completely.
8. anatomical: Relating to the structure of an organism's body.
9. homologous structures: Body parts in different species with similar origin (e.g., bat wing, human arm).

Example Drawings:

• Natural Selection: Draw a population of brown and green beetles on green grass, with a bird eating a brown beetle. Label: natural selection
• Homologous Structures: Draw a human arm, bat wing, and whale flipper side-by-side, highlighting the similar bone structure (humerus, radius, ulna, carpals). Label: homologous structures

Answer:

1. Defined terms with standard biological meanings (listed above)
2. Example drawings provided for natural selection and homologous structures as requested
