Risks in life are often misaligned with our perceptions of these risks. Describe why we fear flying in a plane, nuclear power pl
asambeis [7]

Answer:

We fear flying in a plane, nuclear power plants or being struck by lightning more because our risk perception isn't rational. We assess risks using a mixture of cognitive skills (weighing the evidence, using reasoning and logic to reach conclusions) and emotional appraisals. In this case, we believe that overheating or lack of exercise is something we can control. We believe we can feel the process taking place and we can react in time. We fear all the situations that we cannot control.

Which of the following does not characterize the lungs of birds?
kompoz [17]

Answer:

C) They are compressed during inhalation.

Explanation:

Birds breathe through rigid lungs that are located in the animal's thoracic region. The trachea of birds divides into bronchi that branch inside the lungs into very thin tubes called parabronchials or parabroncholes, which are irrigated by blood capillaries that allow gas exchange.

In birds there are no pulmonary alveoli (as in mammals), but air capillaries that depart from the parabroncholes. Oxygen gas passes from these capillaries to the blood capillaries, thus causing gas exchange.

In the lower portion of the bird's trachea, before branching the bronchi, we can find the syringe, a bag-like structure that has vocal cords responsible for the birds' scream and song. Most of the time, the sound emitted by birds serves to attract the mate, mark territory and prevent birds of the same species against some predator or other danger.
