Answer: Change in a single nitrogen base in the DNA sequence will not have any significant effect on the organism.
So A
Explanation:
This is known as point mutation and it does not have any significant change in the protein and it is least harmful type of DNA mutation.
"The reaction is exothermic and ΔH is negative" can be understood about the reaction and the enthalpy change (ΔH) during the reaction.
<u>Option: D</u>
<u>Explanation:</u>
When the reaction is positive, the process becomes endothermic, i.e. heat appears to be consumed by the system because the reaction products are more enthalpic than the reactants. When the reaction is negative, on the other hand, the process is exothermic, which is the total decrease in enthalpy is caused by heat production. Here the initial temperature is 21.0 C but increase in final temperature to 38.8 C, because if some processes require heat, others must give off heat when they take place.
Answer:
I deeply believe that it would be options 1, 2, and 4? Sorry if i'm wrong and good luck!
