Answer:
1)Habitat Isolation (for lobsters)
2)Temporal Isolation (for flowers)
3)Mechanical Isolation (for snails)
4)Gametic Isolation (for clams)
5)Behavioral Isolation (for birds)
Explanation:
The correct option is deposition.
Deposition is the process by which sediments, soils and rocks are added to a particular rock which result in successive layers in the rock. Deposition is usually brought about by the action of wind, water, ice and gravity. These forces brings on sediments which are added to the rock layers.
The correct answer is C) It recognizes that no resource or species exists on its own.
<span>Ecosystem-based management acknowledge that no resource, specie or anything in the environment is isolated and each one has an impact on the other.
This helps to provide a more holistic approach and helps in better planning and implementation.</span>
They are unique in the sense that sawfish are able to reproduce in the wild without the need of a partner. They were able to engage in asexual reproduction. In parthenogenesis, an egg cell is created by dividing a singular precursor cell into four separate ones. The cell that develops into an egg cell retains the cytoplasm and other vital cellular structures. The remaining three contain excess genetic material.
Fertilization happens when one of the three extra cells essentially turns into a sperm cell and combines with the egg cell.
An action potential is an excitatory presynaptic nerve. An EPSP (Excitatory postsynaptic potential) takes place in the dendrites of the postsynaptic nerve. This spreads passively to the axon hillock. Depolarization of this region opens voltage-gated ionic channels. Sufficient membrane depolarization to threshold opens enough to these channels to produce an action potential.
Non myelinated axon; the currents associated with the action potential spread to the depolarized region of the axon.
In myelinated axon; the currents associated with the action potential spread to the next Node of Ranvier.
The action potential travels down the axon to the axon terminals.
