When the adhesin gene of Neisseria gonorrhoeae were mutated, the pathogen will be unable to attach to the host cells.
<h3>What do you mean by Pathogens?</h3>
Pathogens may be defined as disease-causing agents. These are mostly microorganisms that infect the body of animals as well as humans.
Adhesin gene plays a very vital role in the attachment of pathogens to the host cells. It is the site where pathogen attack and attaches to host cells and then enters the body to play their function i.e. replication, a decline in the host immune system, and finally disease caused.
Therefore, when the adhesin gene of Neisseria gonorrhoeae were mutated, the pathogen will be unable to attach to the host cells.

Answer:
D
Explanation:
Identifying unique features of evidence
Answer:
Mass = 0.61 g
Explanation:
Given data:
Pressure of neon gas = 720 mmHg
Temperature = -15.0°C
Volume = 760 mL
Mass of neon gas = ?
Solution:
720 mmHg = 720/760 = 0.95 atm
-15.0°C + 273 = 258 K
760/1000 = 0.76 L
PV = nRT
n = PV/RT
n = 0.95 atm ×0.76 L/ 0.0821 atm. L. k⁻¹.mol⁻¹× 258 K
n = 0.722 atm. L/ 21.2 atm. L. mol⁻¹
n = 0.03 mol
Mass of neon:
Mass = number of moles × molar mass
Mass = 0.03 mol × 20.2 g/mol
Mass = 0.61 g
