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.

Answer:Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
Explanation:
I believe it is c. The setting has little affect on the reader of a mystery.
The process described which shows the hydrosphere interacting with the lithosphere is river water eroding a rocky bank and carrying silt to the sea which is therefore denoted as option B.
<h3>What is Hydrosphere?</h3>
This is referred to as the combined mass or quantity of water found on the plant such as earth and it comprises of different water bodies such as rivers, seas etc.
Lithosphere on the other hand is referred to as the solid, outer part of Earth which consists of the upper portion of the mantle and the crust in the form of rocks etc.
Water is very important in the ecosystem and is the reason why it is recycled so as to enable its presence which is usually in the form of precipitation. River water which is part of the hydrosphere erodes a rocky bank which forms part of the lithosphere.
