Biology Chapter 1

Front 1

Energy

Back 1

the ability to do work

Front 2

life

Back 2

is characterized by unity and diversity

Front 3

producers

Back 3

make their food from simple materials in the environment

Front 4

consumers

Back 4

cannot make food they eat producers and otherorganizms.

Front 5

Decomposers

Back 5

break down the remains of organizms to simpler raw materials

Front 6

all organisms sense?

Back 6

change in their surroundings and make compensatory responses to them

Front 7

receptors

Back 7

molecules and structures that detect stinuli, which are specific kinds of energy

Front 8

homeostasis

Back 8

state in which phusical and chemical aspects of internal environment (blood, interstitial fluid) are being maintained within ranges that are tolerable for cell activities.

Front 9

DNA

Back 9

Double-stranded nucleic acid twisted into a helical shape; its base sequence encodes the primary hereditary informateion for all living organizms and many viruses.

Front 10

Life's levels of organization

Back 10

starts with a one way flow of energy from the environment through producers and consumers then back to the environment

Front 11

how do organisms maintain their organization?

Back 11

By sensing and responding to change. They try to get back to homeostatious

Front 12

How do organisms grow and reproduce?

Back 12

Organisms grow and reproduce based on information encoded in DNA which they inherit from their parents.

Front 13

How do organizzms interact?

Back 13

Organisms interact through this one way flow of energy and through a cycling of raw materials.

Front 14

genus

Back 14

a genus is a grouping of one or more species characterized by certain traits, at least one of which is unique to the,

Front 15

What are the three domians bioligists favor today

Back 15

bacteria, archaea, and eukarya

Front 16

eukarya

Back 16

protists, plants, fungi, and animals

Front 17

bacteria

Back 17

single cells, prokaryotic (no nucleus). Most ancient lineage greatest motabolic diversity

Front 18

Archaea

Back 18

single cells, prokaryotic, evolutionarily closer to eukaryotes

Front 19

Eukarya

Back 19

Eukaryotic cells (with a nucleus) single-celled and multicelled species categorized as protists, plants, fungi, and animals

Front 20

protist

Back 20

informal name for all structurally simple eukaryotes, which are now being classified as monophyletic groups.

Front 21

plants

Back 21

multicelluar and photosynthetic for the most part

Front 22

animals

Back 22

multicellularconsumers that ingest tissues or juices of other organisms. All animals grow and develop through a series of stages. Most of them actively move about during at least part of their lives.

Front 23

Eukarya classifications

Back 23

protists, fungi, plants, and animals

Front 24

mutations

Back 24

change in DNA from parent to child

Front 25

evolution

Back 25

heritable changer is occuring in a line of descent

Front 26

Natural selection

Back 26

is an outcome of differences in survival and reproduction among individuals of a population that vary in one or more eritable traits, Evolution or chnag in lines of descent gives rise to life's diversity.

Front 27

hypothesis

Back 27

testable explanation of the observed phenomenon or process

Front 28

prediction

Back 28

statement of what you should find in nature if you were to go looking for it. Often called the if then process.

Front 29

scientific theory

Back 29

a time tested intellectual framework that is used to interpret a broad range of observations and data. Scientific theories remain open to rigorous tests, revisions, and tentative acceptance or rejection.

Front 30

scientific inquiry

Back 30

involves asking questions, formulating hypotheses, making predictions, testing predictions, and objectively reporting the results.

Front 31

Experiments

Back 31

simplify observations in nature by restricting a researcher's focus to one variable at a time

Front 32

Variable

Back 32

any feature of an object or event that may differ over time or among representatives of the object or event

Front 33

Mimicry

Back 33

case of looking like something else and confusing predators (or prey).

Front 34

What does science not address?

Back 34

Subjective questions. The external world, not internal convition, is the testing ground for the theories generated in science.
