Correct answer: B). Shelter wood cutting takes place over several years
Shelterwood cutting is the progressively cutting of the forest, in order to establish the growth of the new generation of the seedlings of a particular species without planting.
It is a method of natural tree reproduction under the shelter of old trees, which are removed successively by cutting the tree in order to provide the increased amount of light to the new seedlings. It is a slow process and takes lot of time.
Answer:
Non-covalent interactions.
Explanation:
DNA is present as genetic material in all the living organism except some viruses. DNA also perform important other functions - code for proteins, used as a source of energy.
The DA binds with protein to perform their functions. These proteins may acts as activator for DNA. The proteins binds in the non covalent interactions ( ionic bonding, hydrogen bonding, vanderwalls and hydrophobic interaction) so that proteins may easily detach from the proteins. These interactions helps in the attachment and easily detachment of proteins from DNA.
Thus, the correct answer is non-covalent interaction.

Answer:
When a neuron fires and its electric charge travels down the axon, causing neurotransmitters to be released by the neuron's terminal buttons, an <u>action potential</u> occurs.
Explanation:
An action potential, commonly termed as impulse, can be described as messages which are transferred in electrical form. Action potential are caused due to different electric charges. An action potential is generated by a stimulus which causes transfer of sodium ions into the axons resulting in depolarization of the neuron. To overcome this, potassium ion will enter the cell and an action potential will be generated.
The action potential causes release of the neurotransmitters so that signal messages could be transferred.
