Global warming is heating up their environments and melting away their glacier habitat. If their home ever got completely rid of ice they'd die of a heat stroke.
Answer: Phosphodiester bond
Explanation:
The backbone of DNA consists of deoxyribose nucleotides linked by phosphodiester bridges.
The 3'-hydroxyl of the adjacent sugar of one deoxyribonucleotide is joined to the 5'-hydroxyl of the adjacent sugar by an internucleotide linkage called a phosphodiester bond.
Thus, phosphodiester bond is the answer
When bacteria is divided in to two it is called binary fission, but there is also a process called conjugation
I believe it would be the biosphere hoped this helped!
