Answer:
Personal Opportunity Cost - Spare non drive time sacrifised
Social Opportunity Cost - Fuel efficiency (high pollution), Road Traffic (Congestion issues).
Explanation:
Opportunity Cost is the cost of next best alternative, foregone while choosing an alternative. Bill can commute either by bus, or by self drive.
If Bill drives his car, opportunity cost for him is - the spare time sacrifised, that he could have used while car drive in some other activity (eg reading, listening music).
Opportunity Cost for society is - the fuel utilisation & road traffic management efficiency sacrifised, by using private instead of public transport. This leads to more pollution, more congestion on roads.
Answer:
A. The price would drop to 0.5.
Explanation:
The graph shows that for every increase of 100 units of the goods demanded, price reduces by 1 unit.
When 500 units was demanded, the price was at 1. Therefore, if 550 units are demanded, the price will reduce by half, which means the price would drop to 0.5.
During a patient experiencing a myocardial infarction, the nurse administers morphine sulphate to relieve the aching, sharp pain. On the other hand, the attending nurse also carefully monitors the vital changes which include respiratory rate, blood pressure, ABG and oxygen saturation.
How is respiration controlled by the brain?
The pacemaker, or medullary respiratory control centre, gets three types of input.
- The control centre incorporates these impulses.
- The respiratory centre's output is then changed in timing or strength, resulting in alterations in rate and tidal volume.
- Chemical feedback, mechanical feedback, and information from higher cortical areas are the three types of feedback.
The average person can regulate Pao2, Paco2, and pH within limited ranges.
- The respiratory centre takes information from both peripheral and central chemoreceptors to achieve this degree of control.
- The primary peripheral receptors are situated in the carotid bodies found at each common carotid artery bifurcation.
- Similar structures exist in the aorta, although nothing is known about these aortic entities.
