When health care teams solve problems, it is important that in the final stage, all team members _____. Have a say in the goals
Nadusha1986 [10]

Answer:

The correct answer is ''understand their roles''

Explanation:

Teamwork in a health team is considered important as a way of dividing responsibilities, correctly attending to the roles in a work team and the functions of the figures that intervene in the teamwork in order to achieve recovery the health of the patient more quickly. Each of the health professionals in this group or team must have a role to fulfill the desired objective; the team is a group of individuals who cooperate to perform a particular routine activity; there is a link of reciprocal dependency that unites the members of the same team with the others. This vision is justified, for each professional to have a different perception of the situation, it is the “union” of the different perceptions that facilitates the understanding of the whole, allowing a glimpse of the patient as a whole. Usually, the general doctor assumes the role of knowing the patient in depth, in order to be able to guide on health problems and decide together with him or her the treatments and objectives to be achieved.

It's considered to be an advantage to have lungs with increased capacity, because with increased capacity
matrenka [14]
<span>Having more lung capacity is advantageous because the lungs can expand more. More air in the lungs will fill all the alveoli (air sacs in the lungs) and allow more oxygen to enter the bloodstream via the capillaries that surround the air sacs. Excess waste (such as carbon dioxide) is also transferred from the blood to the air to be exhaled. As lungs fill, more gas exchange can occur.</span>

vivado [14]
The answer is behavioral isolation.

Reproductional isolation is a way to prevent closely related species to mate each other. This is due to reproductive barriers which can be either prezygotic (before fertilization) and postzygotic (after fertilization) barrier. Behavioral isolation is an example of postzygotic barrier. It is based on behavior, including mating sounds and rituals. Thanks to behavior isolation, the different species (in this example gentoo penguins and emperor penguins) will have different mating rituals so they could attract only individuals of their own species, respectively.
