Animal Characteristics

3. Genetic information can be passed from one generation to another
5. Pertaining to the underside, or bottom, of a bilaterally symmetrical animal
6. Pertaining to the back (top) of a bilaterally symmetrical animal
8. Referring to the head end of a bilaterally symmetrical animal
11. an organism that obtains organic food molecules without eating other organisms or substances derived from other organisms.
13. organisms living things that are made of only one cell.
16. An animal with a backbone
17. The process by which one organism makes one or more new organisms.
18. Cells need this to perform tasks such as: transport substances, make new cells, perform chemical reactions
19. a collection of chemical reactions occurring within the body (or cell).
21. species change to pass on advantageous traits
22. an organism that obtains organic food molecules by eating other organisms or their by-products

1. Pertaining to the rear or tail end of a bilaterally symmetrical animal
2. organisms living things that are made of two or more cells.
4. An animal without a backbone
7. Can be divided into two parts are are nearly mirror images of each other; Only one plane of symmetry
8. Cannot be divided into any two parts that are nearly mirror images of each other
9. Can be divided into two parts that are nearly mirror images of each other anywhere through its central axis; Can be divided along more than one plane of symmetry and still have two nearly identical halves
10. An organism's ability to maintain steady internal conditions when outside conditions change.
12. changes that occur in an organism during its lifetime.
14. Reaction to an internal or external force/stimuli (changes in the environment)
15. an increase in size.
20. Organisms are not randomly put together, they are organized; cells are the basic unit of life
