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:
B, C, E.
Explanation:
Unsaturated fats are more likely than saturated fats to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).
Triacylglycerols (triglycerides) are composed of fatty acid residues and glycerol. (because by the reaction between glycerol and 3 long chain fatty acid triglycerides formation occurs and form 3 ester linkages).
Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).
 
        
             
        
        
        
B.) A food chain shows only a single pathway of energy.
Remember that food web are made out of lots of food chains combine. Food chain is only one pathway.
