Answer:
By difference in there ribosomal RNA sequence
Explanation:
Both bacteria and archaea lack membrane-bound nucleus and earlier both are considered in the same categories. Carl Woese was the scientist who discovered that bacteria and archaea are not similar.
Carl Woese and his lab members checked the ribosomal RNA in some archaeans and concluded that the archaeans are more closely related to eukaryotes than bacteria. After the study on archean Carl Woese classified the prokaryotes into two domains i.e., bacteria and archaea.
Therefore by difference in the ribosomal RNA sequence archaeons first distinguished from other prokaryotes.

Driving releases pollutants in the air and when we use gas and oil we are using lots of our natural resources and cutting them down day by day.
Well the whole point of the cell cycle is to make more cells so it could be C, but it also wants the daughter cell to have the same AMOUNT of DNA, not the exact type (in meiosis) so B may be right, but most likely it is C
Answer:
c. If the double helix were unwound, each nucleotide along the two parent strands would form a hydrogen bond with its complementary nucleotide.
Explanation:
According to the Watson-Crick model, two DNA strands are held together by complementary base pairing wherein each nucleotide of one DNA strand forms hydrogen bonds with its complementary nucleotide present in the other strand. During DNA replication, two DNA strands are separated by the action of helicases enzymes.
The separated DNA strands serve as a template for DNA replication. Here, each nucleotide of the template DNA strand binds to its complementary nucleotide by hydrogen bonds. For example, adenine of the template strand forms two hydrogen bonds with thymine while guanine forms three hydrogen bonds with cytosine.
