<span>Water is considered an abiotic factor in the ecosystem because it is a non-living part of the ecosystem. Although water is abiotic, it has great impacts on both living and non-living things. Water is very important to al living things and no living organism can survive without it. Other abiotic factors in the ecosystem are soil, rocks, sunlight, oxygen, etc.</span>
Answer:
Quorum sensing is triggered to begin when<u> a sufficient number of bacteria are present .</u>
Explanation:
Quorum sensing -
Quorum sensing is the ability to detect and to respond to the cell population density by the process of gene regulation . Quorum sensing bacteria releases some chemical signal molecules called the autoinducers , that increases the concentration as the function of the cell density .
The detection of the minimum threshold concentration of an autoinducer leads to the alteration in the gene expression .
Contraction of muscles called peristalisis
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.
Unfortunately you didn't support your question with any options so that I could choose the correct one. But I am pretty sure I've got what you need so in eukaryotes, the components of the electron transport chain are located in the <span>inner mitochondrial membrane.</span>
