Given a scientific passage and an answer, generate a question for the given answer.

[EX Q]: Passage: Plants alternate between diploid-cell plants and haploid-cell plants. This is called alternation of generations , because the plant type alternates from generation to generation. In alternation of generations, the plant alternates between a sporophyte that has diploid cells and a gametophyte that has haploid cells. Answer: alternation of generation
[EX A]: When plant type alternates from generation to generation what is this called?

[EX Q]: Passage: Through asexual reproduction , new organisms are produced that are genetically identical to the parent. That is, they have exactly the same DNA. Fungi reproduce asexually through three methods:. Answer: asexual
[EX A]: What type of reproduction do fungi engage in?

[EX Q]: Passage: Fossils may form in other ways. With complete preservation, the organism doesn't change much. As pictured below ( Figure below ), tree sap may cover an organism and then turn into amber . The original organism is preserved so that scientists might be able to study its DNA. Organisms can also be completely preserved in tar or ice. Answer: fossils
[EX A]:
Tree sap enclosing an organism in amber or an organism preserved in tar or ice are actually examples of what?
