Answer:
C). Bonds between atoms break and reform.
Explanation:
A Chemical reaction is defined as the process in which the substances(two or more) interact and form new substances by rearranging the atom structure of the substances. This process primarily consists of two steps i.e. breaking of chemical bonds that exist between the atoms in the original substances and the formation of new bonds to produce the new substance. Thus, the bonds break and reform. Hence, <u>option C</u> is the correct answer.
Let's calculate the difference in nucleotides. The number of difference multiplied by rate of mutations will help to determine how long ago these two species shared a common ancestor.
Species A: GTACCTAAGTTCACCGAATT
Species B: GAACCTAAGGGCACCGAACT
These species differ in 4 nucleotides.
This number should be multiplied <span>by </span>the rate of mutations
Answer:
The correct answer is B
Explanation:
