Chemical compounds that provide physical structure in organisms

19

What are biological molecules?

20

High degree of order between an organism’s internal and external parts

21

What is organization?

22

Smallest unit that can perform all life’s processes

23

What is a cell?

24

Structures that carry out specialized jobs within an organ system

25

What is an organ?

26

Group of cells that have similar abilities and that allow an organ to function

27

What are tissues?

28

The process in which all organisms produce new organisms like themselves

29

What is reproduction?

30

Large molecule containing the hereditary code for an organism

31

What is DNA?

32

Hereditary information from two individuals is combined in their offspring

33

What is sexual reproduction?

34

35

A short segment of DNA that codes for a protein or polypeptide

36

What is a gene?

37

Single organism divides producing genetically identical cells

38

What is asexual reproduction?

39

Branch of biology that studies organisms interacting with each other & their environment

40
