The cycle runs like this:
Deoxygenated blood enters from the body to the heart via the superior/inferior vena cava. It goes directly to the right atrium and down to the right ventricle. From there it'll pass through the pulmonary artery into the lungs where diffusion will happen in the capillaries. Gas exchanges will occur and the blood will become oxygenated and return to the heart via the pulmonary vein. From the pulmonary vein it will enter back into the left atrium and then will give the final pump of oxygen rich blood into the aorta and then into the entire body.
Answer:
Apoprotein
Explanation:
A peptide is a molecule formed as a result of the linking of amino acid molecules by a peptide bond. The peptide is the backbone of polypeptides and subsequently, protein molecules. Enzymes are proteinous molecules that serve as biological catalysts. The prosthetic group of a protein/enzyme is a metallic attachment to the protein, which plays roles that are vital to its functioning.
However, when the peptide portion of a protein molecule lack its prosthetic group, the protein is called an APOPROTEIN.

B
Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.
The example that does not exhibit sexual selection is:
D. male elephant seals fighting over territory and potential female mates
The competition for territory is also one that helps the elephant seals survive. This is because a seal with a larger territory is likely to have access to a greater amount of resources, ensuring its survival.
