The correct answer is "mucociliary escalator intestines".
The mucociliary escalator is a mechanism that belongs to the bronchi, not the intestines. The mucociliary escalator is a mechanism of self-clearing where cilium, cilia and mucus work together to expel any material that's solid, or not too fluid or gaseous, including pathogens. From the main bronchi to the alveoli there is a moist lining produced by the specific present epithelium. This epithelium presents cilia. The cilia are embedded in mucus. The mucus is what helps in trapping any material that's solid, or not too fluid or gaseous, including pathogens. After these are trapped so that they don't progress to the alveoli, the cilia move in such a way that push the particles again to the exterior of the bronchi, like an escalator.
Answer:
What is the difference between microevolution and macroevolution? Microevolution deals with changes in the gene pool of a single population. Macroevolution considers the broad pattern of evolutionary change over long periods of time and includes the origin of new groups.
At the outer edges of ocean crust
Explanation:
The rocks found in continents are older and in some cases the oldest. The younger rocks are found in mid ridge of ocean. The oldest rocks can be found in ocean trenches that are very deep.
At the outer edges of ocean crust, oldest rocks can’t be found as relatively newer ones are formed continually and mostly found. So, different regions have different ages of rocks and needs to be explored properly.
