In fetal circulation, the ductus venosus bypasses the liver and the ductus arteriousus bypasses the lungs. Ductus arteriosus also called ductus botalli is a blood vessel connecting the main pulmonary artery to the proximal ascending aorta. It does allow most of the blood from right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Ductus venosus on the hand allows oxygenated blood from the placenta to bypass the liver.
Answer:
Antibiotics killed the bacteria that cause infection but they can also kill beneficial bacteria . thus Ms ABC developed a yeast infection and diarrhea after course of antibiotics because antibiotics distrub natural balance of beneficial bacteria in her intestine.
Answer;

Explanation;
-Gap junctions are a specialized intercellular connection between a multitude of animal cell-types. they are organized collections of protein channels in cell membranes that allows ions and small molecules to pass between adjacent cells.
-Gap junctions allow the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.

Here is the steps of the lysogenic cycle. Lysogenic cycle occurs only in temperate phages.
<span>1. After the phage attached to the host cell, it will then inject its own DNA. </span>
<span>2. The inserted DNA circularizes.</span>
<span>3. The DNA is integrated into the host cell DNA. This is done through recombination.</span>
<span>4. Each time the cell replicates, the prophage is reproduced together with the host DNA.</span>
<span>5. The prophage excise itself from the host DNA. But this is very rare.</span>
