<span>Constructing recombinant DNA or rDNA scientists
should combine both DNA from two different species. Based on study, rDNA
is possible if both DNA that should be combined should have the same chemical </span><span>structure.
Most o the DNA do have the same structure they only differ in nucleotide
sequence. </span>
Birds and butterflies don't have a common ancestor because one is a member of a insect and the other is well a bird. They both have different body structure. One has bones and the other has an exoskeleton. hope this helps
With the equation of cellular respiration C₆H₁₂O₆ + 6O₂ → 6CO₂+ 6H₂O, gaseous exchange takes place, glucose reacts with oxygen forming Adenosine Triphosphate used by cells.
About 21% of oxygen and 0.4% of carbon dioxide of air is inhaled while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide because cells use oxygen inhaled to release energy and carbon dioxide as byproduct.
<h3>How does Cellular Respiration work?</h3>
Cellular respiration is how organisms convert fuel into energy and nutrients by combining oxygen with food molecules, sending the chemical energy for life sustaining activities while expelling carbon dioxide and water.
We inhale 21% of oxygen and 0.4% of carbon dioxide and exhale 16.4% of oxygen and 4.4% of carbon dioxide as by product during the process of cellular respiration.

On land but close to oceans. Thus, option "A" is correct.
<h3>What is an earthquake?</h3>
Earthquakes occur as a result of collisions along oceanic-continental convergent boundaries.
The majority of the earthquakes occur alongside the Ring of Fire of the Pacific Ocean. The Ring of Fire is found in the basin which is a land area found close to the coastlines of the ocean. This validates its occurrence on land but close to the oceans.
Thus, option "A" is correct.
