The correct answer is option e, that is, the thermal energy that one feels when one put the hand on the ground originates from the Sun.
The Earth's energy budget holds for the equilibrium between the energy received by Earth from the Sun, and the energy Earth radiates back after having been dispersed all through the five constituents of the climate system of the Earth and having thus fueled the so-called heat engine of the Earth. This system comprises the Earth's water, atmosphere, ice, all living things, and rocky crust.
A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from reversible process in thermodynamics.
Weak acids and bases undertake reversible reactions. For example, carbonic acid: H2CO3 (l) + H2O(l) ⇌ HCO−3 (aq) + H3O+(aq).
The concentrations of reactants and products in an equilibrium mixture are determined by the analytical concentrations of the reagents (A and B or C and D) and the equilibrium constant, K. The magnitude of the equilibrium constant depends on the Gibbs free energy change for the reaction.[2] So, when the free energy change is large (more than about 30 kJ mol−1), then the equilibrium constant is large (log K > 3) and the concentrations of the reactants at equilibrium are very small. Such a reaction is sometimes considered to be an irreversible reaction, although in reality small amounts of the reactants are still expected to be present in the reacting system. A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system, for example, as does carbon dioxide (volatile) in the reaction
Answer:
Explanation:
The dna consists of bases- the order of bases determines the order of amino acids in a protein. Many proteins are responsible for showing a particular phenotype, i.e. physical trait.
