Answer:
Suffling of genetic material increases genetic variation in offspring which is important for evolution.
Explanation:
Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.
In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.
Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.

Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. This indicates that the source of oxygen is water. The photosynthesis involves the transfer of electrons between the photosystem I and II. The water gets split into oxygen, hydrogen ions and electrons in the photosystem I. The electrons move to the photosystem II where the carbon fixation into sugars takes place. The plant A will have O-18 isotope in its synthesised sugar molecule, which gets stored inside it.
