How are they formed<span>? a hydrogen bond is formed when a charged part of a molecule having polar covalent bonds forms an electrostatic (charge, as in positive attracted to negative) interaction with a substance of opposite charge. Molecules that have </span>nonpolar covalent bonds<span> donot form hydrogen bonds.</span>
To classify animals and distinguish them

The lock an key analogy is used because each enzyme has specific substrates that fit into it. This is like how locks only work with a specific key. The enzyme is the lock and the substrates are the key.

This analogy is not perfect because there are often multiple substrates for each enzyme reaction. It only takes one key to turn the lock. The reaction is also taking place between the substrates themselves and not the enzyme. In the lock and key analogy, the lock is affected by the key, but in an enzyme reaction, the substrates are affected by the enzyme.
Hope I’ve helped ;)
Answer:
They are revealed by erosions of the surface of the Earth with time.
Explanation:
The rocks, which have been produced by condensing within the chambers of the magma, that is, deeper within the volcano, managed to come on the surface due to the erosion, which has reduced the layers present over them.
The erosion and weathering are the procedures, which exhibits the capability to flatten and lower the landscape by dissociating apart the rocks present on the surface. Over a long time duration, they possess the tendency to eradicate various layers from the surface, thus, exposing the buried material deep within the surface of the Earth. This is how the rocks produced in the chambers of the magma comes to the surface.
