Explanation: The DNA replication is the process by which one DNA makes exact copies of it during the cell division.
The double stranded DNA is first uncoiled and then, new complementary strand gets added to it and attachment of the nucleotide bases to one another also takes place.
The attachment of bases to one another is complementary which means that the adenine will always combine with thymine and guanine always pairs with the cytosine.
This complementary binding of base pairs prevents error in DNA replication.
Means to increase drag and prevent sinking is the correct answer.
Explanation:
Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.
The substance must be able to alter its physical characteristic (for example, its color) in accordance to a change in pH. One example of this is litmus paper, which becomes red under acidic conditions and blue under basic conditions.
