"Their most important non-carrion food is fish, which they catch by
swooping down and grabbing fish that are near the surface of the water."
We know here that in order to survive, the Bald Eagle needs access to the water - and this water cannot be frozen. So the less ice cover there is, the more food it can obtain!

Since the average osmotic pressure of the brain is 300mM and the concentration of the solution is 280mM, that means there is 20mM difference between the brain cells and CSF. This will induce osmosis and cause water to move from the CSF into the brain until the concentration becomes same. Assuming brain volume is 1200ml and the CSF constantly replaced., then the estimation of fluid should be: 20mM/300mM * 1200ml= 80 ml
If it made percent it should be: 80ml / 1200ml= 6.67%
Hydrogen bonds are classified as weak because they are formed fast, but they also break easily under normal biological conditions.
Weak bonds can be easily broken, but this is extremely important because they are in bold in biological systems. For example, they help to decide and stabilize the shapes of water molecules.
Substrate- level phosphorylation
Answer:
