The right answer is the first phase of the general adaption syndrome.

The concept of stress was introduced by Hans Selye. He describes the mechanism of the adaptation syndrome, that is to say all the modifications that allow an organism to bear the consequences of a natural or operative trauma.

In fact, it is the double-perception of a state of divergence between a demand for adaptation at a given moment and the ability to cope with it. It is an energy expenditure. It can be positive or negative.

The stress syndrome evolves in three successive stages:

*"Alarm reaction": the defense forces are mobilized

*"Resistance stage": adaptation to the stressor

*"Stage of exhaustion": inexorably reached if the stressor is sufficiently powerful and acts a long time.

What does free floating DNA mean ?
ivann1987 [24]

Cells with cell chemicals and genetic material having no defined organelles and are all enclosed within a cell wall are called prokaryotes. Organisms in this group are small in size and are mainly bacteria. Ribosomes in these small cells are also small and ‘free floating’.  DNA in prokaryotic cells is in the form of a circular strand and not as a chromosome.

Have an awesome day! :)

Think about a petal plucked from its flower. When the petal is removed from the flower, will it remain alive according to
schepotkina [342]

When a petal is plucked from a flower, it will not remain alive for very long. It will soon start to decompose.

Explanation:

To understand this, we need to go back to the act of plucking the flower as such from the plant. The moment a flower is plucked from a plant, it stops receiving any further nutrition from the plant. Whatever nutrients were present in the flower at the time of plucking it will continue to keep it alive and once those nutrients are used up, the flower will start to decompose.

In this case, since the petal is plucked from a flower which already was surviving on limited nutrients, it will decompose very quickly.

According to the characteristics of life, it cannot be considered dead at the time it's plucked. It <u>continues to live, but for a very brief time</u>.
