Answer: The correct answer is -
The new DNA molecule consists of one new strand and one old strand of DNA.
DNA replication is a process of formation of two molecules of DNA from a single DNA molecule (which is double stranded).
In this process, the two DNA strands of the original DNA are first separated so that the template strands are exposed.
Using the template strands, enzyme DNA polymerase adds nucleotides (in the direction 5' to 3') in a complementary manner-
For adenine, thymine, guanine, and cytosine in the template strand, thymine adenine, cytosine, and guanine are added respectively.
The new DNA molecule consists of one new strand and one old strand of DNA. That is why, it is also called semiconservative replication.
Thus, option third is the right answer.
Explanation:
Large amounts of heat are needed to evaporate water, because H-bonds need to be broken. Sweating is an example of using water as d coolant. As the sweat evaporates it pulls heat away from the body. Application 'Water's thermal properties, its high specific heat, means that it can cool us.
1) Scientists believe that the ancient ancestors of all animals were <span>single-celled eukaryotes that sometimes grew in colonies.
</span>Eukaryotic cells have membrane-bound organelles such asmitochondria<span> and the Golgi apparatus.

<span>B) single-celled eukaryotes that sometimes grew in colonies</span>
The first organic compounds may have been nucleotides and make up nucleotides. Nucleotides bond together to form RNA or DNA. RNA and DNA make up genetic codes. So all of these make up each other in a sort of chain or order.
