<span>It
is important to characterize and identify unknown environmental bacteria
because it is a potential pathogen. This means that it could be harmful to
anyone. Thus, it is necessary to characterize and identify them in order to
distinguish one organism from another and to group similar organisms by
criteria of interest. Hence, bacteria are everywhere and they are part of our
environment and even of us and through. Through identifying them can help us
determine the cause of a disease or to test if a certain food is safe to eat or
simply to know what is present in a certain ecosystem. </span>
Any illness arising due to spoilage of food that is due to contaminated food, viruses, pathogenic bacteria or parasites that contaminates food is known as food-borne illness.
The large quantity of food can be chilled or heated quickly by dividing and placing the food into small and shallow containers.
I feel it is the contribution on cotemporary physics.
This is more current than even modern physics.
Please mark me as brainliest.
Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
