A strain of Neisseria gonorrhea has a mutation which has caused it to lose the ability to produce fimbriae and become less virul
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.

iren [92.7K]

Answer:

1. Latitude. Kuala Lumpur is located in the equatorial zone, near the equator, so it receives a lot of sun for the  entire year, and this explains its warm climate.

2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.

3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.

4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.
