In assessing the adequacy of the patient's breathing. The healthcare practitioner should observe the rise and fall of the chest. In this inspection, the healthcare practitioner can assess two things: (1) patency of the airway and (2) the adequacy of breathing. A decrease or asymmetry in chest expansion may point out to pathologies such as pleural effusion or pneumothorax.
Answer: Membrane proteins act as receptors to molecules like hormones.
Explanation:
Membrane proteins are proteins that are closely associated with a cell membrane. On the cell membrane, they could act as receptors to molecules like hormones that need to be transported across the hydrophobic lipid bilayer.
A good example of membrane proteins is sodium channel, that acts as receptor to neurotransmitters.
III is the correct answer
Paleomagnetism is the study of the terrestrial magnetic field during rocks formation or geological processes. The correct option is D. <em>The study of the </em><em>magnetic qualities </em><em>of </em><em>ancient rocks.</em>
-----------------------------
Paleomagnetism is a branch of geology, and refers to the study of the terrestrial magnetic field registered at the moment of a rock formation or during subsequent relevant geological processes, such as metamorphism.
It is based on three basic assumptions:
- Axial geocentric dipole
- Record of the primary magnetic field
- Invariable record in time
The paleomagnetic analysis includes a series of control tools used to verify que acomplishments of these assumptions in the study area.
The correct option would be option <em>D. The study of the </em><em>magnetic qualities </em><em>of </em><em>ancient rocks.</em>
