Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.
Explanation:
Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.
Plate tectonics located in our crust crashing or colliding into each other cause earthquakes to occur.
Answer: Your guess is right
Explanation: Other reactions release energy, so forming sucrose from glucose and fructose is endoergic. Also a water molecule is formed.
When two molecules form new molecule, order is increased and energy is needed that. IT could also possible to use standard energies of formation.
