Answer 3

Amoebozoan

Question 4

One of two prokaryotic domains of life.

Answer 4

A surface-coating colony of prokaryotes that engage in metabolic cooperation.

Answer 8

Biofilm

Question 9

The use of living organisms to detoxify and restore polluted and degraded ecosystems.

Answer 9

Bioremediation

Question 10

One of a group of marine, multicellular, autotrophic protists belonging to the stramenopile clade; the most common and largest type of seaweed. This organism includes the kelps.

Answer 10

Question 11

A type of protist that has unicellular amoeboid cells and aggregated reproductive bodies in its life cycle; members of amoebozoan clade.

Answer 11

Cellular Slime Mold

Question 12

An organism that obtains both energy and carbon from inorganic chemicals. This organism makes its own organic compounds from CO2 without using light energy.

Answer 12

Chemo-autograph

Question 13

A group of bacteria that live inside eukaryotic host cells. Includes human pathogens that cause blindness and nongonococcal urethritis, a common sexually transmitted disease.

Answer 13

Chlamydia

Question 14

Answer 17

Diatom

Question 18

A member of a group of protists belonging to the alveolate clade. These organisms are common components of marine and freshwater phytoplankton.

Answer 18

Dinoflagellate

Question 19

A thick-coated, protective cell produced within a bacterial cell. This microorganism becomes dormant and is able to survive harsh environmental conditions.

Answer 19

Endospore

Question 20

A poisonous component of the outer membrane of gram-negative bacteria that is released only when the bacteria die.

Answer 20

Endotoxin

Question 21

A poisonous protein secreted by certain bacteria.

Answer 21

Exotoxin

Question 22

A microorganism that lives in a highly saline environment, such as the Great Salt Lake or the Dead Sea.
