The following physical properties of minerals can be easily used to identify a mineral:
Color.
Streak.
Hardness.
Cleavage or Fracture.
Crystalline Structure.
Diaphaneity or Amount of Transparency.
Tenacity.
Magnetism....ect
I would say the the mechanism of control and co-ordination in plants and animals is called the Hormonal Feedback Mechanism. Since hormones command many cell functions, they are very important for homeostasis. Hormones control many cell activities, so they are very important for homeostasis or the stable functioning of an organism. These hormones are managed by feedback mechanisms. Such a mechanism feeds back to control its own production. It does this in a continuous loop.

Option C - Secondary Succession
<u>Explanation </u>
Secondary succession occurs in an ecosystem after a lava flow has completely covered the surface of an area of land. Secondary succession is a method originated by an incident that decreases an already organized ecosystem to a less group of varieties and secondary succession happens on pre-existing clay example forest fire, harvesting, hurricane, and similar. It is a succession is the type of succession which can take place after the destruction of the area. Examples include areas which have been cleared of existing vegetation.
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.
* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.
Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.
A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules
The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.
