Ksju [112]

Answer: The pathogen has lost the function of the ability to adhere to cells of the body.

Explanation:

Neisseria gonorrhea is a gram negative bacteria that has the ability to attack and cause disease in man using its virulent factors. It is know to attack the urethra of both male and female producing an acute urethritis and tenda to spread locally if not treated. The virulent factors determines the ability of the organism to infect or damage it's hosts tissues and they include:

--> endotoxins

--> pilli

--> fimbriae

--> capsule polysaccharide expression

The fimbriae is one of the virulent determinants which the organism uses to attach to the host cells. As these bacteria multiple and grow, there are chances of mutation occuring. MUTATION is defined as the errors during DNA replication or induced by exposure to mutagens (like chemicals and radiation)

If the bacteria is affected by mutation, which can cause the gene for fimbriae production not to be expressed, the virulent factor of the organism will be highly affected as the first step to cause an Infection which is attachment is lost.

Sophie [7]

The correct sequence for the five phases in the systems development life cycle (SDLC) process is system analysis, conceptual design, physical design, implementation and conversion, and operations and maintenance

The study of life cycles is crucial to fostering children's global awareness and assisting them in grappling with difficult ideas like life, death, and birth. A life cycle approach can aid in our decision-making. It means that everyone has a responsibility and a part to play throughout the entire chain of a product's life cycle, from creation to disposal, taking into account all pertinent repercussions on the economy, the environment, and society.

A life cycle is a progression of stages that a living creature experiences. Life cycles are common to both plants and mammals. Diagrams are useful for illustrating the stages, which sometimes involve beginning as a seed, egg, or live birth, then growing up.
