Answer:
DNA REPLICATES
Explanation:
During G1 phase, the cell grows in size and synthesizes mRNA and protein that are required for DNA synthesis. Once the required proteins and growth are complete, the cell enters the next phase of the cell cycle, S phase.
If a disconformity is present in a region then it is likely that the region experienced extensive and prolonged denudation. Denudation is the laying bare of the land by the processes of mass wasting, weathering and erosion. A disconformity is a type of unconformity involving a non-sequence of beds. Sedimentary rocks that were exposed to denudation over time has some strata removed and then has new strata deposited without a change in the underlying or subsequent overlaying rocks. This makes disconformities hard to identify.
solution:
Thermodynamically favorable reaction is the products, because the reaction occurs spontaneously, without the need for energy to be added.
Because a reaction is thermodynamically favoured does not mean that it will be a fast reaction. So 'yes' they always proceed but possibly infinitesimally slowly. Temperature is the most common way of quickening a reaction. Of course a catalyst also does so but this generally by changing the way the reaction occurs, i.e. the mechanism is different using a catalyst but the product is the same. Enzymes are natures catalysts, in synthetic chemistry (and in you car exhaust) metal based compounds are often used.
All reactions have an activation energy EaEa between reactants and products and a small increase in the size of this can slow a reaction exponentially. Experimentally, the rate constant is generally found be of the form k=k0exp(−Ea/RT)k=k0exp(−Ea/RT), which is the Arrhenius equation, with R the gas constant and T the temperature in Kelvin

Viruses are the exception too the cell theory, but they have some characteristics of living things. What is one of these characteristics?
Genetic material.
