If there are respiring organisms within that sample of air, the partial pressure of oxygen decreases because the organisms utilize it for respiration activities.
Answer:
1. As the cell size increases, the ratio of surface area to volume DECREASES
2. It depends on the unit of the ratio 6:1. If it is in cm−1, then it means that it is similar to a cell of size 1 cm^3, which is normally too big to get materials from the surface
.
3. A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly. So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1
HOPE THIS HELPS!!!
Answer:
This is a map of a Mountain landform because the rings get smaller until the top of the mountain. Also the altitude goes up until it reaches the top.
