Increased in pitch (frequency). It's the doppler effect.
Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
The soil is first "normalized", using pioneer species such as lichens, algae and fungi.
After this, plants able to survive in less harsh conditions such as grasses.
Therefore, the fertility of soil during early years of primary succession does not increase much and it is a process that involves a long period of time.
Incomplete question. Here are the missing parts.
What will happen to the substances in this diagram to bring the concentrations closer to equilibrium?
A. The solute will flow into the cell from the surrounding environment.
B. Nothing will change--it is already in equilibrium.
C. Water will flow into the cell from the surrounding environment.
D. Water will flow out of the cell and into the surrounding environment.
My answer:
D. Water will flow out of the cell and into the surrounding environment.
The solute cannot pass through and go inside the cell, water has to flow from the cell to the surrounding environment to bring the concentration closer to equilibrium.
Answer:
B. Collect Water
Explanation:
Collecting Water is NOT a function of the excretory system.
