Answer:
Basic solution.
Explanation:
Solution that contains high percentage of the base in solution are called basic solution because it has more amount of 'Hydroxl or Hydroxide' ions or (OH-) ions. When we put few drops of the red litmus solution or paper in the solution which contains high percentage of the base, it turns red colour in to blue.
So, here the blue colour indicates that the solution is basic in nature.
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:
0.13 s
Explanation:
We'll begin by converting 24900 mile to metres (m). This can be obtained as follow:
1 mile = 1609.344 m
Therefore,
24900 mile = 24900 mile × 1609.344 m / 1 mile
24900 mile = 4.01×10⁷ m
Finally, we shall determine the time taken for light to circumnavigate the Earth, this can be obtained as follow:
Distance = 4.01×10⁷ m
Speed = 2.998×10⁸ m/s
Time =?
Speed = distance / time
2.998×10⁸ = 4.01×10⁷ / time
Cross multiply
2.998×10⁸ × time = 4.01×10⁷
Divide both side by 2.998×10⁸
Time = 4.01×10⁷ / 2.998×10⁸
Time = 0.13 s
Thus, it will take 0.13 s for light to circumnavigate the Earth.

Explanation:
When 3‑bromopentane reacts with hydroxide, (Z)-pent-2-ene will produce through E 2 (Z)-pent-2-ene.
Mechanism
Hydroxide ion (OH⁻ ) is a strong nucleophile so it abstract the proton from carbon next to the carbon attached with bromine.
The the carbon next to carbon of bromine gets -ve charge, mean while it shares its electrons with the carbon having bromine and make a double bond.
As bromine is a good leaving group so it easily gets detached from carbon, so that carbon comes to its normal state.
As a result (Z)-pent-2-ene will produce. we call it Z because mostly trans products will form.
