Answer: The average global temperature has increased by a little more than 1°. The temperatures we experience locally and in short periods can fluctuate. In the past, a one- to two-degree drop was all it took to plunge the Earth into the Little Ice Age. The strong warming trend of the past four decades likely reflects a shift

Answer:
c)Recruit the transcription factors and RNA Polymerase that compose the pre-initiation complex.
Explanation:
Transcription leads to formation of RNA from DNA. The process is carried out by RNA Polymerase which forms a RNA strand according to the template DNA strand.
It starts by the formation of pre-initiation complex. RNA Polymerase along with transcription factors binds to the promoter region of DNA and forms the pre-initiation complex. Generally the eukaryotic promoters have a sequence called as TATA box where the transcription factors bind first. Eventually RNA polymerase also binds to the region and the DNA strands separate starting the transcription process.
If a claim is based on science, it will have a lot of scientific experimentation, replication of results, peer view, and proofs obtained from a lot of researches that substantiate investigated theory. However, if a claim is based on pseudoscience, instead of evidence that supports a theory, there would be claims that doesn’t follow specific criteria.
this is what i got from google
