As Abe continued his fitness regimen, he started to think more about his muscle anatomy. He wondered how he was able to adjust the force generated by his muscles when he lifted different weights. His anatomy instructor explained motor units to him. Which of the following best explains how motor units are involved in controlling force exerted by muscle?
A. A single motor neuron innervates a specific set of muscle tibers within each muscle. When more force is needed, more motor units are activated, which states mere matice fbers to contract
B. A motor unit in composed of all the muscle fibers within a singie tascich Addition fascicles will be activated when more force is needed
C. Each skeletal muscle fer is innervated by a single motor neuron, so there are as many motor neurons as fibers within a single musch When more force is needed addition motor neurons will be activated, and their individual fibers will contract
D. Each muscle has one motor neuron that can selectively activate as many foers as are needed when trying to in heaver objects a single motor neuror will just some more Ebers to contract Submit Putn Muscle shorteninn

Answers

Answer 1

Answer:

d). A single motor neuron innervates a specific set of muscle fibers within each muscle. When more force is needed, more motor units are activated, which stimulates more muscle fibers to contract.

Explanation:

The last statement most appropriately elaborates the role of motor units in directing the force applied by the muscles. It correctly states that 'a one motor neuron excites a particular range of muscle fibers in every muscle. In the situation of extra force required, there is an activation of extra motor units that assists in arousing the extra muscle fibers to shrink.' This contraction of muscles fibers in the concept 'motor units' assists the body to handle the distinct forces exerted by the body muscles when various weights are lifted. Thus, option d is the correct answer.

Answers

Answer:

I think it's A. <:

There is a cultural lag between having the Internet and using the technology to its full capacity likely accounts for the difference in preference. The correct option is B.

There is a cultural lag between having the Internet and using the technology to its full capacity. This means that even though most people have access to the Internet, they are not yet comfortable using it to make all of their purchases.

There are a number of reasons for this, including:

Lack of trust: Some people are not comfortable giving their credit card information online.

Fear of fraud: Some people are afraid that they will be scammed if they make online purchases.

Preference for in-person shopping: Some people simply prefer to shop in stores where they can see and feel the products before they buy them.

Option A is incorrect because there is no evidence that advertisers are discouraging consumers from making online purchases.

Option C is incorrect because there are many resources available to help people learn how to order clothing online.

Option D is incorrect because many people do have their own personal computers and use them to shop online.

Here are some additional reasons why people might prefer to shop in stores instead of online:

They want to try on clothes before they buy them.They want to see the clothes in person to get a better sense of the quality.They want to be able to return clothes if they don't like them.They enjoy the experience of shopping in stores.

It is likely that the cultural lag between having the Internet and using it to its full capacity will eventually disappear. As more and more people become comfortable with online shopping, the number of people who prefer to shop in stores will likely decrease. B is the correct option.

In the Christian Church, what are the two ceremonies which are carried out to show a person’s commitment to their faith?

Answers

Answer:

The two ceremonies carried out to show a person's commitment to their faith are baptism and confirmation.

Explanation:

In Christian Churches, we often hear of baptism, which is a person's commitment to his or her faith as a Christian. It is often said, especially in protestant churches, that the person has accepted Jesus Christ as their Lord and savior. Being baptized means that person will do his or her best to stay faithful to the Church's principles, beliefs, and rules.

Another form of commitment is known as confirmation, which is a practice in the Catholic Church. Catholics baptize their children as babies. Once those children grow up, they may reaffirm their faith and commitment to the Church through the confirmation ceremony. In other words, confirmation is a second baptism.
