Materials become harmful when they contain substances or properties that is dangerous or can harm human beings and cause damage to cells.
I found the whole exercise on the internet. Here are the events mentioned:
"-<span>Mismatched bases in the heteroduplex trigger mismatch repair.
-Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
-A heteroduplex is formed between </span>R (wild-type) and r (mutant) alleles.
-Mismatched bases are excised from the R (wild-type) allele.
-The wild-type R allele is converted to the mutant r allele."
The correct order is:
1. Gaps in the R (wild-type) allele sequence are filled by copying the r (mutant) allele.
2. A heteroduplex is formed between R (wild-type) and r (mutant) alleles.
3. Mismatched bases in the heteroduplex trigger mismatch repair.
4. Mismatched bases are excised from the R (wild-type) allele.
5. The wild-type R allele is converted to the mutant r allele.
The answer to that question is the one on the fort home answer

Explanation:
Answer:
Russia was somewhere next to North America when Pangea was still in 1 piece. A coal deposit formed on the border, and Pangea drifted apart, separating the coal deposit into 2.
