In this task, you are given a paragraph, and your job is to generate comma-separated entities present in the given paragraph. Generate entities from a given passage in such a way that (i) they are present in the paragraph, (ii) they are non-duplicate, (iii) they underwent a state change during the process. Avoid creating entities that (i) aren't present in the process paragraph and (ii) aren't significant. 

[Q]: Bees go out during the day and gather food. Then while gathering of their food, they make wax, which is the building block of their bee hive. Bees make food called honey. They use a sticky, glue-like substance called propolis as a binding to hold their hives together. Bees produce all of the building blocks to build their hive in their own body. 
[A]: bees ,food ,wax ,honey ,propolis ,hives 


[Q]: MRNA is made during the first step of protein synthesis, which is transcription. The DNA's genetic information, or secret code, gets written onto a strand of mRNA. Transcription takes place in the nucleus. The next step in making a protein is called translation. The mRNA attaches itself to the ribosome.

The ribosome figures out where to start on the mRNA by finding a special three letter "begin" sequence called a codon. The ribosome then moves down the strand of mRNA. When the ribosome sees the "stop" code, it ends the translation and the protein is complete.

[Q]: Two large veins bring blood to the heart. The blood enters the right atrium. The blood flows through the tricuspid valve. The blood travels into the right ventricle. The blood goes through the pulmonary arteries to the lungs. Blood picks up oxygen in the lungs. Oxygenated blood enters the left atrium. Blood goes to the left ventricle. Blood leaves the heart via the aorta to the rest of the body. The deoxygenated blood returns to the heart. 
[A]:
oxygenated blood ,deoxygenated blood ,oxygen
