Question 3

Four of the five answers listed below are at least characteristics of some of the bacteria.Select the EXCEPTION.
A) heterotrophy
B) photosynthesis
C) chemosynthesis
D) Multi-cellular
E) no nucleus

Accepted Answer

Bacteria are typically unicellular organisms and do not have specialized tissues or organs, so they are not multi-cellular. The other characteristics listed are all at least characteristics of some bacteria.

Question 4

Four of the five answers listed below are related by a common association.Select the EXCEPTION.
A) archaea
B) methanogens
C) photoautotroph
D) halophiles
E) thermophiles

Accepted Answer

All of the other answer choices are types of extremophiles, organisms that thrive in extreme environments. Archaea is a domain of unicellular microorganisms that include extremophiles such as methanogens, halophiles, and thermophiles. Methanogens are a type of archaea that produce methane gas as a metabolic byproduct. Halophiles are extremophiles that thrive in high saline environments, while thermophiles are extremophiles that thrive in high-temperature environments. Photoautotrophs are organisms that use photosynthesis to produce their own food, but they are not necessarily associated with extreme environments.
