Size and the ability to carry objects with it
Answer:
both: soled at room temp, they are made of molten
sedimentary: are made of weathered pieces of rock, form above the surface
igneous: form in the earths crust, and the big definition
Explanation:
There are basically 3 types of pharynx- nasopharynx, oropharynx and laryngopharynx.
The function of the pharynx are:-
1. To transport the food from mouth to esophagus.
2. To warm, moisten and filter the air, before it moves to the trachea, and then to the bronchi, the bronchioles, the alveoli and at last to the lungs.
Therefore, pharynx(or throat) is a part of both- digestive and respiratory systems.
3. It is also important for vocalization.
<span>Myelination enhances the speed of action potential propagation.
The difference between myelinated and unmyelinated axons are in the propagation of action potential. In unmyelinated axons, the action potential travels continuously through the axons. On the other hand, among the myelinated nerve fibres, transmembrane currents can only occur at the nodes of Ranvier where the axonal membrane is exposed, so the excitation of the axonal membrane jumps from node to node. This propagation is called saltatory conduction and this movement of depolarization wave is much faster than in unmyelinated fibres.</span>
The two adaptations of endo parasites:
- Endoparasites (a parasite that lives in the internal organs or tissues of its host) produce some compounds of anti-enzymes which defuse or inactivate the host's digestive enzymes.
- Endoparasites maintain their osmotic concentration equivalent to or significantly lower than the host cell for easy absorption of host water and nutrients.
There are three main classes of parasites involve:
- Protozoa include Plasmodium, the single-celled organism. A protozoa inside the host can only replicate, or split.
- Helminths parasites are worms.
- Ectoparasites: These are living on, not in their hosts.
