I have no clues tbh......
Explanation:
- One of the main differences between adult and fetal circulation is <em>the direction and where the non-oxygenated and oxygenated blood circulates</em>. In adults arteries carry oxygenated blood away from the heart and veins carry non-oxygenated blood towards the heart; in fetuses, arteries carry non-oxygenated blood away from the heart and veins carry oxygenated blood back to the heart.
- Another difference is <em>where does the exchange of gases takes place</em>, in fetuses blood is oxygenated in the placenta, in adults in the lungs.
- The circulation between adults and fetuses differs in <em>where does the pressure increases</em>, in adults is on the left side of the heart, in fetuses on the right side.
- Finally,<em> another important difference between adults and fetuses is the presence of shunts</em>, in fetuses these shunts allow both sides of the heart to work parallelly letting mix blood from both ventricles. This shunt gets closed after birth, so adults do not have them.
I hope you find this information useful! Good luck!
Answer:
C) Non-protein-coding DNA that is transcribed into several kinds of small RNAs with biological function.
Explanation:
The genome of humans consists of a variety of protein-coding and non-protein coding sequences. The protein-coding sequences are the sequences which can get translated into the protein sequences.
When the genome was sequenced, it was expected that the size of these coding sequences will be larger but the sequences came to be smaller. This shows that the rest of the genome is made of the non-coding sequences.
The importance of these non-coding sequences is that they do not form the proteins but they can undergo transcription and form the variety of RNA molecules like the regulatory RNA, the ribosomal RNA and others.
Thus, Option-C is the correct answer.
