Molecules of opposite chirality would be toxic to the ones that currently exist on earth right? So that would mean that the L molecules already in existence on earth would be toxic to the newly introduced D molecules? I'm not really sure about this, anyone have more chemistry/Biology background?
No, not every organism needs oxygen to survive. Some organisms, like anaerobic bacteria, can survive in environments with no oxygen or low oxygen levels. These organisms can use other substances, like nitrogen or sulfur, as alternative electron acceptors in their metabolic processes.
An obligate aerobe is an organism that requires oxygen to grow and survive. These organisms rely on aerobic respiration to produce energy.
An organism that can survive without oxygen belongs to the kingdom Monera, specifically in the domain Archaea. These organisms are known as extremophiles and are capable of thriving in extreme environments such as deep-sea vents.
Oxygen is a non-living element. It is essential for living organisms to survive and carry out cellular respiration, but it is not considered a living organism itself.
The amount of oxygen an organism needs to survive varies depending on its size, metabolic rate, and activity level. Generally, larger organisms with higher metabolic rates, such as humans, require more oxygen to function properly than smaller organisms. In humans, the average adult at rest consumes about 250 ml of oxygen per minute, which increases during physical activity.
how does the environmental determine where an organism can survive
The fittest is the organism that can survive where others cannot dare survive.
Symbiosis help organisms survive by giving an organism's nutrients and energy to another organism.
how unicellular organism survive
The living material of a living cell is primarily composed of proteins, lipids, carbohydrates, and nucleic acids (DNA and RNA). These biomolecules form the structures and carry out the functions necessary for the cell to survive and perform its specific roles in the organism.
By digesting its prey.
To survive
Traits that enable an organism to survive and reproduce are known as adaptations. Each organism has specific adaptations suitable for its environment.
they have to have things to survive and to adapt to with there organisms
It is an organism's ability to survive and reproduce.
