Why is evolutionary change constrained by its past but impossible to predict?

Short Answer

Expert verified

Evolution has no clear ulterior motive, so the evolutionary change constraint is impossible to predict.

Step by step solution

01

Evolutionary constrain

The evolutionary constrain are the limitation or biases on the outcome of adaptive evolution.All evolution is constrained.

02

Evolutionary change is impossible to predict

Pre-existing elements constrain the new structures and metabolic functions. Because evolution lacks a clear ulterior motivation, it is impossible to predict.

Moreover, the genetic variations occur randomly that why evolution is generally unpredictable. However, the observed recurring convergence of evolution leads to the occasional loss of pigmentation in living things.

Hence, evolutionary change constrained by its past is not possible to predict.

For the reaction A鈫�Bat 298 K, the change in enthalpy is-7kJmol-1and the change in entropy is -25kJmol-1. Is the reaction spontaneous? If not, should the temperature be increased or decreased to make the reaction spontaneous?

At 10掳C,Keqfor a reaction is 100 . At 30掳C,Keq=10Does enthalpy increase or decrease during the reaction?

Label the following statements true or false:

(a) A reaction is said to be spontaneous when it can proceed in either the forward or reverse direction.

(b) A spontaneous process always happens very quickly.

(c) A nonspontaneous reaction will proceed spontaneously in the reverse direction.

(d) A spontaneous process can occur with a large decrease in entropy

The equilibrium constant for the reaction Q鈫�Ris 25.

  1. If 50渭Mof Q is mixed with 50渭Mof R, which way will the reaction proceed to generate more Q or more R?
  2. Calculate the equilibrium concentrations of Q and R.
