Answer: Na+ channels are closed
Explanation:
The refractory period describes a period between the initiation of an action potential (where Na+ channels are active/open), and immediately after the action potential’s peak. In the absolute refractory period, action potentials cannot be generated, as Na+ channels are in an inactive or closed state, they usually take around one or two minutes.
After the absolute refractory period the relative refractory period (RRP) occurs. During the RRP, it is hard to send another action potential. Na+ channels are once again open, but the cell remains hyperpolarized- its membrane potential, remains negative. Recovery from inactivation is voltage and time-dependent; Action potentials would require an influx of more positively charged ions. These must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
Agency problem
Agency problem also known as agency costs occurs in a two-party relationship (principal/agent) where the agent is expected to act or make decisions for the good of the principal.
For example in a corporate the relationship between the management and shareholders. The management is expected to make decisions that will maximize shareholders interest. The problem arises when the two parties have different interests. In the example above the manager may opt to make his own wealth and not act in the company’s best interest which could be maximizing company’s market value.
Examples of agency relationship in finance
Managers/stockholders
Managers/Creditors
Causes of conflicts between managers and stockholders may include;
Remuneration - low remunerations or fixed salaries despite increased profit margins.
Differences in risk profile- stockholders may prefer high-risk return investments contrary to the managers. When high-risk investment go bad the manager risks job loss
Manipulation of accounting systems- to reflect high profits.
Unnecessary perks management award themselves.
Solution to these problems include threat for firing in case of poor performance, shareholders may also threaten to sell the company, remuneration based on performance, incurring agency costs-these are costs incurred while hiring external auditors, setting a control system, legal costs for employment letters and contracts.
Agency problem may be reduced by motivating the manager to act for the companies best interest by offering incentives

Answer:
Breathing Is Automatic and Not Autonomic
Conscious factors can override or modify automatic functions of the respiratory control system for a limited period. For example, an individual can voluntarily speak, smell, hyperventilate, or hold their breath.
