A) the archaea

B) the protistians

C) the fungi

D) all of the above

Back 1

A) the archaea: single cells; all prokariotic

Front 2

What are the 3 domains of life?

Back 2

Archaea, Bacteria, Eukarya

Front 3

Characteristics of Domain Archaea

Back 3

Single cells; all prokaryotic. Producers, consumers, decomposers. Mostly live in extreme anaerobic habitats.

Front 4

Characteristics of Domain Bacteria

Back 4

Single cells, all prokaryotic. Producers, consumers, decomposers.

Front 5

Characteristics of Domain Eukarya

Back 5

Contains four kingdoms: protists, fungi, plantar, animalia

Front 6

Protista

Back 6

Mostly single cells, larger than bacteria. Eukaryotic. Producers and consumers.

Front 7

Fungi

Back 7

Mostly multi-celled. Eukaryotic. Decomposers, consumers.

Front 8

Plantae

Back 8

Mostly multi-celled. Eukaryotic. Producers.

Front 9

Animalia

Back 9

Multicelled. Eukariotic. Consumers.

Front 10

The molecule associated with energy transfer in living organisms is:

A) deoxyribonucleic acid

B) lipids

C) ATP

D) carbon

Back 10

C) ATP

Front 11

A community and its physical and chemical environment constitute:

A) a population

B) the biosphere

C) an ecosystem

D) an organ system

Back 11

C) an ecosystem

Front 12

Levels of organization of life on earth:

Back 12

Population: actively interbreeding organisms in a particular area

Community: the populations of all species in a particular area

Ecosystem: a community and its nonliving physical surroundings

Biosphere: all the Earth's ecosystems

Front 13

The molecule of inheritance is:

A) deoxyribonucleic acid

B) lipids

C) ATP

D) Carbon

Back 13

A) deoxyribonucleic acid: (DNA) carries the hereditary instructions for assembly of proteins; genetic blueprint or molecular instruction manual for production of proteins

Front 14

Which of the following is not a requirement of all living things:

A) reproduction

B) metabolism

C) adaptation

D) aerobic respiration

E) none of the above

Back 14

D) aerobic respiration

Front 15

The one-way flow of energy through the biosphere starts with energy input from:

Back 15

The sun

Front 16

Characteristics of all living things:

Back 16

1) organization (order) and complexity

2) metabolism

3) motility

4) responsiveness

5) reproduction

6) development

7) heredity

8) evolution

Front 17

Multicelled orgqnisms have complex levels of organization:

Back 17

Subatomic particles → atoms → molecules → organelles → cells → tissues → organs → organ systems → organisms.

Front 18

What is metabolism?

Back 18

Metabolism is the cell's capacity to obtain and convert energy from its surroundings and uses energy for maintenance growth organization and reproduction.

Front 19

What is motility?

Back 19

Living things have self propelled movement

Front 20

What is responsiveness?

Back 20

Living things respond to changes in the environment; are also able to maintain relatively constant internal conditions, homeostasis.

Front 21

Whwtbis reproduction?

Back 21

Asexual: produces offspring that are genetically identical to parent (clones)

Sexual: offspring are genetically different than parents

Front 22

What are growth and development?

Back 22

Multicellular organisms: growth means producing more cells

Single cellular organisms: grow before asexual reproduction; duplicates itself for division

Front 23

Mutations

Back 23

Changes in the structure, sequence, or number of parts of DNA

Front 24

How are organisms identified scientifically?

Back 24

Organisms can be identified by a genus and a species name. Ex: Quercus alba (white oak) *italicized*
