The answer is left to right shunt
Ductus arteriosus is a vessel that connect the pulmonary artery with the aorta. Normally, ductus arteriosus will be closed to prevent backflow. Patent ductus arteriosus happens when it doesn't closed.
Since aorta pressure is higher than pulmonary, left to right shunt will be happens. The blood that flow to the lungs will be increased while blood flow to the systemic decreased.
Many biological systems classify the organism based on the cells, reproduction, simplicity and complexity. The discovery of the new species and arrangement based on the hierarchy led to the change.
<h3>What was the new classification system?</h3>
Aristotle gave the most primitive biological hierarchical classification system that was replaced by the system of the Linnaeus. He gave the classification based on the taxonomy groups.
With time many new organisms and species were discovered that did not fit in Aristotle's classification system. Hence, with time new systems were established to classify the organism based on many new parameters.
Therefore, option A. new system was established to classify the new organism discovered.

Answer: The following statements <em>comparing respiration in fish and in mammals</em> is correct:
- The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.
Explanation:
<u>Breathing </u>is the process by which living beings <em>exchange gases</em> with the external environment. It consists of the <u>entry of oxygen</u> into the body of a living being and the <u>exit of carbon dioxide</u> from it .
Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :
- Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
- Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).
Answer:
uaa
Explanation:
An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.
