True or False?
1-Worldview is defined as a metaphysical (belief system greater than physical evidence)
construct, model or systematic body of thought that attempts to coherently describe man
and the experiences common to all men.
2-An ideology is a system of thought used to interpret reality, society and mankind’s
place in the world. It functions to stabilize social structures for its adherent’s goals and
beliefs. Ideologies often take on lives of their own with their own traditions and
institutions. Ideologies often substitute for religion and often lack self-critique.
3-Religion has been defined by a number of scholars and dictionaries, as God’s revelation
to man and man’s response to God. Religion is an active and total response to what is
experienced intensely as an ultimate or transcendent reality.

level brought about by mutation, natural selection, gene flow and genetic drift.

93-Mutation rate is the probability of a gene mutating during or in between DNA
replication. Mutations usually occur in most species between 10-5 and 10-6 per gene locus
per gamete (egg or sperm) in each generation.

emigration. Gene flow tends to counter natural selection by supplying genes to
neighboring populations.
98-Genetic drift is an allele frequency change over generations brought about by random
chance. This variation usually occurs through what is termed “sampling error” when
genes are replicated during cell division. Genetic drift is more severe when the number of
individuals in a population is small. In this situation, there is a greater chance that a given
allele will become less prevalent over time.
