Which sources of evidence did wegener use to support his theory of continental drift? check all that apply.
fossils
land features
climate change
satellite mapping
warm equatorial climates

Option A, B and C

Explanation:

Alfred Wegener postulated a hypothesis that all present continents were once part of a large continent (usually termed as super continent) which later on moved and led to the formation of tectonic plates.  

He collated this theory after comparing the age and material type of rock fossils from both the sides of Atlantic Ocean. Both types of rock fossils have the same composition. He also compared the fossils from ancient glaciers and bio species. Also, the major coal deposits that aroused from the coral reefs and swamps led to formation of coal in the tropical and subtropical regions.  

Hence, option A, B and C are correct

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

i am going to guess that it is co2.
