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.

Elis [28]

Answer:

A. These homologous structures indicate that these four organisms all share a common ancestor.

Explanation:

Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.
