Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This type of cell can survive in conditions without oxygen, such as deep ocean trenches.
A
prokaryotic
B
eukaryotic
C
both prokaryotic and eukaryotic
D
neither prokaryotic nor eukaryotic
Explanation: 

Detailed explanation-1: -The biosphere’s earliest life-forms, called prokaryotes, survived without oxygen. Ancient prokaryotes included single-celled organisms such as bacteria and archaea.

Detailed explanation-2: -Prokaryotic cells which are facultative anaerobic make ATP by aerobic respiration if oxygen is present, but can also survive without oxygen.

Detailed explanation-3: -Facultative anaerobes are adaptive prokaryotes that can survive in either aerobic or anaerobic environments. These organisms are capable of both cellular respiration, through use of the electron transport chain along the cell membrane, and fermentation.

Detailed explanation-4: -Prokaryotes may perform aerobic (oxygen-requiring) or anaerobic (non-oxygen-based) metabolism, and some can switch between these modes.

Detailed explanation-5: -Almost all prokaryotes have a cell wall: a protective structure that allows them to survive in both hyper-and hypo-osmotic conditions. Some soil bacteria are able to form endospores that resist heat and drought, thereby allowing the organism to survive until favorable conditions recur.
