What is the role of alveoli in respiration
Burka [1]

These vessels are carrying Co2 rich blood to exchange at the alveoli. The O2 from the alveoli is diffused into the blood while co2 is sent into the lungs. That O2 rich blood is then carried to heart to pump it to the whole body. and this process continues. </em><em>The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.</em>

Can you tell the difference between the original and the replicated strand
kati45 [8]

Answer:

Original strand is the old strand and replicated strand is new strand.

Explanation:

DNA is replicated by the semi-conservative way which means the new strand is replicated over the old strand and one DNA duplex has one new strand and one old strand. So the original strand is the old strand and the replicated strand is the strand that is synthesized over the original strand.

In DNA the replicated strand is made by adding nucleotides complementary to the opposite nucleotide present in the template or original strand. Adenine and thymine make complementary base pairing with each other and guanine and cytosine makes complementary base pairing with each other.
