Answer:
Referendum: This is a direct vote in which an entire electorate is asked to either accept or reject a particular proposal, issue or question. A referendum may result in the adoption of a new constitution, a constitutional amendment, a law, the recall of an elected official or a specific government policy. It could be simply be where voters decide on what time pubs shut, how long shops stay open etc.
Genersl:This is a formal decision making process by which members of the population (voters) elect a representative. This could be for numerous things, we are familiar with government and political parties but it also applies to other areas. We use elections in our unions, governing bodies whether they are in education or the NHS, business organisations, clubs, voluntary associations and corporations too. Elections ensure positions are voted in and filled with law-makers, decision-makers and governance.

Answer: Karl Von Baer was an Estonian biologist and generalized the observations around embryology into laws bearing its name.
His laws indicate that the earlier we are in the embryonic phase, the closer the classes of distant organisms look to each other. As embryos develop, they diverge further from embryos of other species.
The von Baer sequence poses more problems for evolutionary mythology since natural selection cannot explain the pattern of embryonic development. Natural selection does not want to know if a trait is widespread or specific. It does not see attributes so it cannot sort them according to a special sequence.
