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+.

Answers

Answer 1
I think the answer is D
Answer 2

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.

Medicalization has numerous phenomenology consequences. Define phenomenology and give two examples of medicalization effecting how we experience our bodies

Answers

Answer:

Explanation:

Phenomenology is the study of an individual's lived experience of the world.

I would go just a bit further. It is the experience, I call it life poetry, that shapes us. These are pretty drastic in some cases, or pretty lovely in others. Falling in love is an example of great love poetry. Being rejected is pretty negative, and very formative.

I know that is not what you are asking, but it gives you an idea of powerful these events can be.

This is another way of asking the same question you've been asked before. Pain killers are an example of a kind of medication that prevents us from feeling what otherwise could be a dreadful experience that our bodies make us focus on. The most serious of these are something like morphine. It kills the pain, but it also makes us more Zombie like then we'd like to be. It robs us of our vitality and it deadens the way we respond to the world around us.

Other drugs prevent our chemistry from raising h e  l l by seeing things that aren't there.

We engage in analysis to record info. For example, when we create immunization there are clinical trials. This is to monitor symptoms. We engage to help the greater population of the world.

One reason why  we engage in causal analysis despite knowing the possible negative effects of that behavior or activity is it help to identify potential issues, solve them now, and create a plan of action to fix problems and it could also help in preventing future problems and to achieve any greater cause.

anything that hampers any stage of the communication process refers to

Answers

The correct answer to this open question is the following.

Although there are no options attached we can answer the following.

Anything that hampers any stage of the communication process refers to "noise."

If we take teh Harold Laswell model of Communication as a reference, we can observe how there is a Communicator of "Who" that transmits a message or "Says what" throughout a channel or medium. The message gets to the receiver with a specific effect. To complete the model, there is some feedback from the receiver so the communicator confirms his message was correctly received. In between each of these components of the model, can be "noise" that can interfere with the clarity of the message.

That is why the communicator should transmit the message with clarity, precision, in time, and be specific.

The correct answer is "imagination."

Wright Mills once said that sociologists need to develop a sociological imagination to study how society affects individuals.

Wright Mills (1916-1962) coined the phrase "social imagination" and he wrote a book about this topic. The book is titled "The Power Elite."

In this book. Mills wrote about the way relationships are created in power elites such as the United States military, and the political world. where most of the time the end result is the creation of alliances not often seen by society.

For Mills, sociology needs that "imagination" to develop a different perspective of the reality in the societies. Mills always appealed to the awareness of having the experience to understand the sociological phenomenon.

Each of the students (Lorenzo, Luis, Oscar, and Christian) had different skill sets. Describe how each of them contributed to the team?

What is one major life lesson you learned from this movie?

How did the boys persevere through difficult times during the movie?

Answers

Answer:

In 2004, four Latino teenagers arrive at the Marine Advanced Technology Education Robotics Competition at the University of California, Santa Barbara (USCB); born in Mexico, raised in Phoenix, Arizona, where they attend an underfunded public high school.

Oscar Vazquez goes to an Armed Forces Career Center to enlist into the U.S. Army; while he is waiting for his interview, he sees a video announcement and brochures about a Marine Underwater Robotics Competition, an event sponsored by NASA and the United States Armed Forces. Although he distinguishes himself as part of the Carl Hayden High School Junior Reserve Officer Training Corps, he is forbidden to join because of his status as an undocumented immigrant; he is recommended not to present himself to any government office to avoid being reported to the Immigration and Customs Enforcement (ICE) agency. Vazquez lies to his mother about his progress in the Army; looking for another way to move ahead in life, he investigates the Underwater Robotics Competition.

With no previous formal teaching experience and between jobs, Fredi Cameron interviews for a vacant substitute teacher position at Carl Hayden High School. The principal questions his job stability record, but eventually hires Cameron because of his PhD and engineer credentials. After the interview, while in the school's parking lot, Lorenzo Santillan overrides Cameron's car temperature safety sensor for $20 to avoid a more costly repair job.

Explanation:

As part of his normal teaching responsibilities, Cameron is assigned to oversee an engineering club, where he meets Vazquez, who is looking for help to build a remotely operated underwater robot for the UCSB robotics competition. Cameron grudgingly accepts to help, even though he doesn't feel he is going to remain at the school for long.

Vazquez, looking for more kids to join the engineering club, talks to teacher Gwen Kolinsky, who recommends Cristian Arcega. After agreeing to help, Arcega takes the technical lead of the project and sketches an early design of the potential robot. Before starting to build it, Cameron suggests a prototype so they can do a proof of concept model.

Cameron starts to learn about the competition rules and requirements, which demands the robot to successfully complete a series of underwater tasks. Kolinsky offers to help teaching him about the PBASIC programming language, to implement the robot's intelligence module.

After catching Santillan stealing from the principal's car, Cameron forces him to join the team and the now named Robotics Academic Club, so he can help with the mechanical design and building of the prototype. They later recruit Luis Aranda, for being strong enough to help lift the machine in and out of the pool.

Because of a lack of funds to see the project through, the team starts looking for spare parts and asking for donations from the local businesses, which raise $663.53, plus $134.63 given by Cameron himself. The small budget forces them to scale back the original design and to innovate in how the robot is constructed, including the glue which gives the robot its name, "Stinky".

Needing to go from Phoenix to Santa Barbara creates problems because three of the four boys were undocumented immigrants from Mexico. The day before the competition, they have to fix a critical electrical problem, due to a leak in the case that protected the intelligence module, by using tampons to contain the water.

They face several highly funded college teams; the team from MIT is backed by a $10,000 grant from ExxonMobil. The Phoenix teenagers scraped together less than $1,000 and built their robot out of scavenged parts. Yet their robot finishes the practical segment of the competition in fourth place with 75 points after missing three tasks. They are still hopeful for a chance to make it into third place because 30% of the total score would be based on the judges' technical evaluation and interview of the teams.

The night of the awards ceremony, they are given a Special Achievement award, which the team assumes is their final result. They are later surprised when they are announced as the champions of the event.
