The rigth answer is the picture 4.
In the case of a hypotonic extracellular medium, there will be a large inflow of water to dilute the Na, thereby increasing the cell volume and there will be an explosion of the membrane in places so hemolysis, the contents of the red cell ( Hemoglobin) is released into the blood plasma.
On the other hand, in the case where the extracellular medium is hypertonic, therefore archi concentrated, well it will be the water of the red cell that will come out without damaging the membrane, we will rather have a red cell that is completely flat and non-functional without release. erythrocyte (Hb) content.
A. competitive exclusion.
Parasitism, Commensalism, and Mutualism are all types of symbiotic relationships.
At this point in time, we have yet to reach the carrying capacity for humans. So yes there is a carrying capacity for humans we just haven't reach it yet.
Yes, they do. Many plants will have seed pods (like dandelions) that fly away or drop off. This helps distribute the seeds and promotes more plants being grown elsewhere. Another adaptation would be having their seeds inside fruits. This causes other animals to eat it and distribute the seeds that way in their waste.
