The MRI shows every slice of the brain, a CT shows circulation, possibly the outside of the brain.
I think it’s algal blooms but i’m not sure.
Gravity causes the raindrop to accelerate to the ground at a rate of 10m/s². However, air friction acts against this gravitational acceleration by reducing the rate of acceleration of the raindrops. The higher the friction surface of the raindrops the lower the terminal velocity.
There are some reasons which could be mentioned:
1)Energy is lost as heat at each feeding level
2)Consumers who feed directly on plants have more energy for themselves than consumers feeding on other consumers. Indeed, energy again is lost in each level.
3)Feeding cattle is not productive, because energy must be transferred from plants to the cattle and then to people.
The rock walls would be wethered down by the water and would chip off and be grinded down
