Answer:
Explanation:
Water washed disease are diseased that occur due to lack of water for proper personal use.
Often common in areas with predominantly poor people.
Water borne diseases are disease that are are transmitted by pathogens and micro organisms in water. Bacteria and protozoan are major carriers of water borne disease. When exposes to contaminated water one could get the disease from there.
Both water borne and water washed diseased are characterized by pathogens and micro organism.
They both result in serious medical condition that requires treatment via drug administration.
Lack of proper hygiene can result in both water washed and water borne disease.
Answer:
the waters acts as a solvent for chemical reactions and also helps transport dissolved compounds in and out of cells.

Infection is the invasion of an organism's body tissues by disease-causing agents, their multiplication, and the reaction of host tissues to these organisms and the toxins they produce. Infectious disease, also known as transmissible disease or communicable disease, is illness resulting from an infection.
Gram's staining is a differential staining technique that employs a primary stain like crystal violet and a counter stain like safranin along with the decolourizing agent alcohol and a mordant called the Gram's iodine.
Iodine is a mordant added after the primary stain. It fixes the stain by combining with it to enchance the staining ability. This forms an insoluble crystal violet iodine complex appearing purple under the microscope. These microorganisms are classified as Gram positive.
If addition of iodine is skipped, crystal violet is not fixed on the slide and the insoluble complex is not formed. The cells are decolourized by alcohol and are stained by the counter stain safranin making the Gram positive cells wrongly indentified as Gram negative due to its pink colouration. Thus, the slide will show all the cells as pink coloured Gram negative cells.
