Answer:
Use a head tilt (tilting the head backward) and chin lift to prevent the tongue from obstructing the upper airway, and look for the foreign body that is causing the obstruction.
Explanation.
The backward head tilt and chin lift will prevent the tongue from obstructing airflow.
If the foreign object can be seen and removed, do so. Usually, it is not wise to use the fingers unless the foreign object is visible and accessible.
The next step is to perform CPR because the patient is unresponsive.
Answer:
Permeability of plasma membrane is the rate of passive diffusion molecules across the biomembrane.
Introduced species
Ecosystems are complex systems that are in dynamic equilibrium with constant interactions between their parts.
When a new species is introduced, new interactions will occur, generating new components of the system and also competing with the previous interactions between the species already present in the system, which normally ends up generating an imbalance in the ecosystem mentioned, i.e a disruption in it.
Ectoparasites cause diseases in humans and animals, so to know the format of detecting it we need to know that ......
<h3>Ectoparasite</h3><h3 />
Parasitism is defined as an interaction where a parasitic organism obtains resources through one or several host individuals, causing damage and reducing its fitness. The endoparasite is a type of parasite that lives inside the host's body (from the Greek endos, inside), while the ectoparasite is one that lives on the external surface of its host (from the Greek ectos, outside). Thus, the ectoparasite does not need to lodge inside the host organism to feed, presenting a partial metabolic dependence. Some examples of ectoparasites are:
<h3>Strategies of ectoparasites</h3>
Each parasite has particular strategies and adaptations used to extract nutrients from their hosts. In ectoparasites these adaptations can often be seen as changes in the oral apparatus, allowing them to penetrate the skin surface and feed on the host's nutrients. Scabies is a skin disease caused by the ectoparasite <em>Sarcoptes scabiei</em>. In order to obtain nutrients for its survival, the parasitic organism burrows into the skin of the host, unlike ectoparasites such as the louse, which pierce the surface and only insert its mouthparts to extract food.
<u>With this information we can say that the </u><u>ectoparasites </u><u>adapt to the host so that it is </u><u>not noticed </u><u>and for a better </u><u>absorption of nutrients </u><u>from the host, they remain </u><u>undetectable</u><u> not to be </u><u>removed</u><u>, so that they are not </u><u>disconnected</u><u> from their </u><u>food source</u><u> as they are in the vast majority visible to the eye.</u>
