Which of the following statements concerning the differences between action potentials in skeletal muscle cells and in ventricular cardiac muscle cells is TRUE?
A. Like skeletal-muscle cells, ventricular cardiac-muscle cells have a resting membrane potential closer to the sodium equilibrium potential than to the potassium equilibrium potential.
B. Unlike skeletal-muscle cells, the initial depolarization of ventricular cells is mainly due to calcium influx, not sodium influx.
C. After sodium influx through voltage-gated channels occurs in ventricular cells, a prolonged influx of calcium occurs. No such calcium influx occurs in skeletal muscle cells.
D. Action potentials in skeletal muscle cells are longer in duration than action potentials in cardiac muscle cells.
E. The efflux of K+ repolarizes skeletal muscle cells after an action potential, while repolarization in cardiac muscle cells is due to the efflux of Ca2+.
The difference between action potentials in skeletal muscle cells and in ventricular cardiac muscle cells is that the action potential of cardiac muscles is for a lesser duration than skeletal muscle. Thus, option D is correct.
The skeletal muscles have been present in the body that has been responsible for the skeleton movement. The cardiac ventricular muscles have been the muscles of the heart ventricles.
The difference between the skeletal muscle cells and in ventricular cardiac muscle cells can be given as:
The skeletal muscles and cardiac muscles have the resting membrane potential of -90 mV, which has been close to the potassium equilibrium. Thus statement A is incorrect.The depolarization of the ventricular cells has been based on the movement of the sodium ion outside the cells. Thus, statement B is incorrect.The skeletal muscle has been able to transfer the signal through the Ca efflux by the acetylcholine signals. Thus, statement C is incorrect.The action potential of cardiac muscles lasts for msec, while the action potential for skeletal muscle lasts for 2-5 sec. Thus, statement D is correct.The repolarization of the cardiac muscles has resulted in an increase in the permeability of the cell for Potassium. Thus, statement E is incorrect.
The difference between action potentials in skeletal muscle cells and in ventricular cardiac muscle cells is that the action potential of cardiac muscles is for a lesser duration than skeletal muscle. Thus, option D is correct.

Deci and Ryan (1985, 2001) have proposed that there are three fundamental needs that are required for human growth and fulfillment: relatedness, autonomy, and competence. Susan predicts that students who have these needs met in their psychology class feel happier and more satisfied with the class. She collects data and finds that students who feel more related and competent do feel happier but that feeling more autonomous does not seem to matter. Susan thinks that maybe autonomy is only necessary when people are in situations in which they are not being evaluated. This scenario is an example of which scientific cycle?
a) Basic-applied cycle
b) Journal-journalism cycle
c) Theory-data cycle
d) Peer-review cycle

Please describe how the choice of cosleeping or independent sleeping is a good example of a custom complex, and the underlying cultural beliefs each choice
represents.
Answer:
Due difference in cultural beliefs.
Explanation:
The choice of co-sleeping or independent sleeping is a good example of a custom complex, and the underlying cultural beliefs because in some of the culture, co-sleeping is considered as a bad habit and prohibited by the culture but encourages independent sleeping while on the other hand, some culture allows the co-sleeping due to no prohibition in their cultural believes so we can say that custom complex is responsible for this choice of sleeping.

to what extent has the government to support the support victims of xenophobia
Answer:
Provides help and safety.
Explanation:
The government has to support the victims of xenophobia because the actions of racism happen under their rule and government. The government should provide safety to the victims and takes action against the people who are responsible for the actions. The government should compensate the losses that occurs to the properties due to the actions of the people so the government has to play a significant role to help people experience xenophobia.

If you think more carefully about your plan to complain to the company's CEO, I'm sure you will agree with me that it is not a good idea. After all, I am your boss. I have more experience than you, and I decide who gets fired around here.
Required:
a. Does it commit a fallacy?
b. Does it commit an appeal to pity fallacy?
Answer:
a. Yes.
b. No.
Explanation:
The argument presents a fallacy called Argumentum ad verecundiam, or appeal to authority. A fallacy is an argument that makes disjointed premises to establish itself as true, even if it is not. Appeal to authority is the fallacy that appeals to the relevance of an authority to present an argument as true and to justify a behavior or event. In the above argument, we can see that the speaker, having the authority to dismiss employees, states that this authority should be taken into account when employees want to make complaints to the CEO of the company, when in fact the complaints and the authority of the speaker are not related .
We can see that the argument does not make an appeal to pity, because this is the fallacy where the speaker plays the victim to try to win the listener's sympathy.
Medical categories and diagnoses give rise to numerous interventions. At times, these interventions are ‘enforced’. Detail an example of an enforced intervention and discuss how the certification of medical label legitimates this process.
Answer:
Explanation:
This is one of the most complex questions that medical profession has to face.
I'm 81. My wife of 40 years passed away last year. We filled out something in Alberta Canada called the Green form. It is in a green folder and it must be in a prominent place where it can be seen easily. Of course there is only 1 entrance to my room and the back of the door is pretty prominent.
Alberta Health insists that this form must be filled out and signed. I'm telling you this so you will understand what I'm going to write next.
My wife, before she succumbed to the immense pain of the kind of Cancer she had, studied the form carefully. It is a legal document and it ties the hands of the medical profession so that what you are describing cannot happen. Because she studied it so carefully, my form says exactly the same thing hers did.
In effect, the form is a directive that tells the medical profession what they may and may not do. They can keep me comfortable while I still breath. They cannot intervene and make me live a tortured life because they have taken an oath to do that sort of thing.
If what they are planning is a standard response to my kind of Cancer, they can do that. If it deviates in anyway and just prolongs me in a vegetable state, they cannot do anything at all to prolong my life. This takes the responsibility away from my family. My daughter had (at 17) to make this sort of decision for her mother. It was a terrible thing to do to a 17 year old. She had to do it for one parent. She will not have to do it for the one remaining parent that she had.
(The woman I was speaking of above was my second wife. I was not consulted on the first wife's death).
There is no process I know of that can force a patient to live beyond the point where they don't wish to. The only exception to that is when children are involved. Then the medical profession can do what the think is necessary to save a life. That does not necessarily mean prolonging it.
If you are going to pursue this topic at any length, I highly recommend that you read Eric. You will be reading about a young man who died in his girl friend's arms who was with him when he died.
It is a magnificent book written by a compassionate (American) mother who operated without the green folder. In the end she had to make the decision to let go. There was no way an intervention would have done any good.

When businesses produce goods ansld services that consumers do not want?
Answer:
Technical or productive inefficiency.
Explanation:
Factors of production can be defined as the fundamental building blocks used by individuals or business firms for the manufacturing of finished goods and services in order to meet the unending needs and requirements of their customers.
Basically, there are four (4) main factors of production and these are;
I. Land.
II. Labor (working).
III. Capital resources.
IV. Entrepreneurship.
Furthermore, when these aforementioned factors of production are combined effectively and efficiently, they can be used for the manufacturing or production of goods and services to meet the unending requirements or needs of the consumers.
In Economics, there are two types of inefficiency associated with the production of goods and services, these includes;
1. Allocative inefficiency: it occurs when businesses do not maximise output from the given inputs.
2. Technical (productive) inefficiency: it occurs when businesses produce goods and services that consumers do not want. This is typically as a result of the incorrect and inefficient allocation of scarce resources by a business firm or entity.

Answer:
During the credits, it is revealed that Ray successfully graduated as he and Fahmarr reunited with their completely sober mother.
Explanation:
Ray McElrathbey is a freshman at Clemson University, having been accepted on a football scholarship for their team, the Tigers. He is quickly thrust into campus life as he tries to balance his school work and football career. He begins to receive numerous phone calls from his younger brother Fahmarr, but tries to ignore him to study. He quickly takes an interest in sports journalist student Kaycee Stone while also butting heads with football captain Keller. One day, Ray learns that Fahmarr is not at home with their mom, Tonya, and races back home over the weekend to find that their mother has relapsed and Fahmarr has been staying with a former acquaintance, presumed to be a dealer. Ray takes Fahmarr to child services and, faced with the prospect of losing Fahmarr to the system, decides to take him in, albeit temporarily so that Tonya can recover in a month.
