The process of change that has transformed life on Earth from its earliest beginnings to the diversity of organisms living today.

Evolution

1

The scientific study of life

Biology

2

list the characteristics of life

- order
-energy processing
- growth and development
-response to the environment
-regulation
-reproduction
-evolutionary adaptation

3

The highly ______ structure that characterizes life. What every living thing must have.

order

4

use of chemical energy

energy processing

5

inherited information carried by genes controls the pattern of

growth and development

6

response to the__________stimulus of

response to the environment

7

adaptations that evolve over generations or changes over generations

evolutionary adaptations

8

response to changes and maintains a constant

regulation

9

organism reproduce their own kind

reproduction

10

definition of life

we recognize life by what living things do

11

Name the levels of Biological Organization

1. The Biosphere
2. Ecosystems
3. communities
4. populations
5. organisms
6. organs and organ systems
7. tissues
8. cells
9. organelles
10. molecules

12

consist of all life on Earth and all the places where life exists; Most regions of land, most bodies of water, the atmosphere to an altitude of several kilometers and even sediments far below the ocean floor

Biosphere

13

all living things in a particular area such as deciduous forest, grasslands, deserts, and coral reefs

ecosystem

14

The array of organisms inhabiting a particular place or a biological community is called

communities

15

consist of all the individuals of a species living within the bounds of a specified area, ex a community

populations

16

what living things are called

organisms

17

a body part that carries out a particular function in the body and is composed of organs

organ system

18

consist of multiple tissues

organ

19

a group of cells together, performing a specific function

tissues

20

life's fundamental unit of structure and function

the cell

21

functional components that present in cells an ex, is chloroplasts are examples

organelles

22

a chemical structure consisting of of two or more units called atoms an example is Chlorophyll

molecules

23

A powerful strategy in biology, which reduces complex systems to simpler components that are more manageable to study. Provides a necessarily incomplete view of life on Earth. An example is Zooming in at ever-finer resolutions

reductionism

24

allows us to see emergent properties at each level that are absent from the proceeding level

reductionism

25

the arrangement and interactions of parts as complexity increases, not unique to life, especially challenging to study

emergent properties

26

the exploration of a biological system by analyzing the interactions among its parts

exploring emergent properties more fully, complementing reductionism with systems biology

27

can be used to study life at all levels

system biology

28

provides insight into its structure and organization

function

29

gives us clues about what is does and how it works

analyzing biological structure
