Answer:
The first 5 are exothermic reaction because heat is in product means heat is evolved or given out.
And last no reaction shows that heat is required so last reaction is endothermic reaction.
Explanation:
And heat is evolved in exothermic reaction and heat is absorbed in endo thermic reaction
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:
c
Explanation:
because of the law of gravity
Answer:
B
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither <u><em>created</em></u> nor <u><em>destroyed</em></u> in chemical reactions. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Iodine&chlorine contain negative charge.so they are anion.When we do electrolysis those charge go to anod&become ion.
