Yes, some prokaryotes (such as certain bacteria) are anaerobic and can survive and thrive in environments without oxygen. Many eukaryotes, including some unicellular organisms like yeast, can also survive without oxygen through fermentation or other anaerobic metabolic processes.
No, leeches require oxygen to survive as they have a respiratory system that relies on oxygen in the environment. Without oxygen, leeches would not be able to obtain the necessary energy for their survival.
Man needs oxygen to survive. Oxygen is essential for cellular respiration, which produces energy for the body's processes. Without a constant supply of oxygen, humans cannot survive.
Oxygen accumulation in the atmosphere came before Eukaryotes. Around 2.4 billion years ago, photosynthetic bacteria began to produce oxygen as a byproduct of photosynthesis, leading to the Great Oxidation Event. Eukaryotes, which possess specialized organelles like mitochondria that utilize oxygen for energy production, evolved around 2 billion years ago.
No, a rat-tailed maggot, also known as the larva of a drone fly, needs oxygen to survive. This aquatic larva breathes through a long, telescopic breathing tube called a "rat tail" that it extends to the surface of the water to take in oxygen. Without access to oxygen, the maggot will not be able to survive.
Anaerobic bacteria are unable to tolerate oxygen. They can only survive in environments without oxygen or in low oxygen conditions.
They can't survive without oxygen but they can survive with an oxygen mask that scuba divers use and with supply of oxygen of course .
not a single cell in the body can survive without oxygen. without oxygen, the cells won't be able to accomplish their work!
Prokaryotes are (mostly) unicellular organisms without an nucleus.Humans on the other hand are multicellular eukaryotes. Our cells contain nuclei EXCEPT for red blood cells. These do not contain a nucleus in order to be able to transport more oxygen.
Anaerobes
Fermentation primarily occurs in the cytoplasm of the cell in both prokaryotes and eukaryotes. It is a metabolic process that allows cells to generate energy in the absence of oxygen by converting sugars into other compounds like alcohol or lactic acid.
No, a plant could not grow without oxygen.
Anaerobic bacteria are able to survive and grow in environments without oxygen. These bacteria use alternative electron acceptors, such as nitrate or sulfate, for energy production in the absence of oxygen. Examples of anaerobic bacteria include Clostridium species and Methanogens.
No.
An example of an organism that can survive with or without oxygen is a facultative anaerobe like the bacterium E. coli. Facultative anaerobes can switch between aerobic respiration in the presence of oxygen and fermentation in the absence of oxygen to generate energy. This flexibility allows them to adapt to varying environmental conditions.
No, leeches require oxygen to survive as they have a respiratory system that relies on oxygen in the environment. Without oxygen, leeches would not be able to obtain the necessary energy for their survival.
Prokaryotes. They are single-celled organisms without a nucleus. They were the dominant life form then. They lived in the ocean and the earliest prokaryotes lived without oxygen.
Cells can typically survive without oxygen for only a few minutes before irreversible damage occurs.
