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 is the key substance found in the developing buffer?
Alenkinab [10]
Enzyme linked to the secondary antibody   
an undetermined measure of antigen is joined to a surface, and after that a particular counter acting agent is connected over the surface with the goal that it can tie to the antigen. This counter acting agent is connected to a catalyst, and in the last stage a substance is included that the compound can change over to some distinguishable flag, most normally a coloration change in a concoction substrate is seen.

How are viruses different from bacteria
Butoxors [25]

I believe the correct answer is that viruses are not cells while bacteria are cells with organelles.

<h2>Explanation:</h2><h3>Viruses</h3>

Viruses can simply be explained as genetic materials enclosed in capsules that protects them from the immune system.

Viruses need a host to survive since they lack a mechanism to replicate in meaning they are obligate intracellular organisms.

Reproduction of viruses is through attaching their DNA or RNA into the machinery of the host that replicates them as part of the normal DNA of the cell.

They are the smallest living organisms and cannot be seen microscopically.

They cannot be infected but rather can infect bacteria

They have a capsid that protects the viral material and also contains the receptors attachments that are able to attach to the specific sites which they are infecting. Some of them have an extra layer of a membrane that is called an envelope that further protects the viruses from their hostile environment

They are treated by antiviral medications that affects their replication on normal cells.

They are pathogenic by destroying the cells they enter after successfully replicating their genetic material.

They can either have DNA or RNA but never both.

<h3>Bacteria</h3>

They are cellular prokaryotes with cell organelles that keeps them functional

They can be obligate intracellular organisms or they can survive outside the cell without any problem depending on the particular species of the bacteria since they have cell organelles that can function.

Bacteria reproduce through a process called binary fission where the cell organelles just double up and the cell pinches into 2 different sections with equal distribution of genetic materials forming 2 different cells.

They can be infected by types of viruses called bacteriophages that use the hosts nucleoid to replicate.

They have a cell membrane and a cell wall which encloses the inner contents of the bacteria and also protects the bacteria from the immune system.

They are treated by antibiotics such as β-lactam antibiotics that destroys their cell wall making it porous and the cell eventually dies.

They do not enter the host for reproduction but rather they kill the host through toxins such as toxin A and toxin B

They do not have a nucleus but have the nucleoid that contains the DNA of the bacterium.
