rosijanka [135]3 years ago

4 0

Answer: The answer is 3,5,1,4,6,2

Explanation: A muscle contraction is an increase in the tension (force exerted by the muscle on a bone) or a decrease in the length of a muscle. The steps that occurs during muscle contraction are:

1. Depolarization of the T-tubules causes release of calcium from the lateral sacs of the sarcoplasmic reticulum.

2. Calcium binds to the troponin-tropomyosin complex in the actin filaments,releasing the inhibition that prevented actin from combining with myosin.

3. Myosin head attaches to the exposed site of actin and forms cross bridges by utilizing energy from ATP hydrolysis. It is at this stage that the contraction of the muscle occurs .

4. ATP binds to the myosin cross-bridge, breaking the actin-myosin bond and allowing the cross-bridge to dissociate from actin.

5. Cross-bridge activation continues as long as the concentration of calcium remains high enough to inhibit the action of the troponin-tropomyosin system.

When stimulation ceases, calcium moves back into the lateral sacs of the sarcoplasmic reticulum .

6. Removal of calcium restores the inhibitory action of

troponin-tropomyosin. In the presence of ATP, actin and myosin remain in the dissociated, relaxed state.

A basic tenet of self-perception theory is that we infer our feelings from our behavior when____a.the reasons for our attitudes

icang [17]

Answer:

a. the reasons for our attitudes or feelings are ambiguous

Explanation:

The Self-perception theory suggests that individuals tend to perceive their own behaviors as good or bad or acceptable or unacceptable and then this affects their own feelings and attitudes. In addition to this fact, it has also been reported that people tend to infer their attitudes and their preferences based on their behaviors not only when they are observing themselves but also when they are behaving unconsciously. This means that people infer feelings from their own behavior and actions and since these feelings can be interpreted in multiple ways hence they are ambiguous. Therefore, option a is the correct answer.

What factors created a climate favorable to reform in the early nineteenth century.

enot [183]

These factors include an increase in business and the need for workers, a growth in civic engagement in politics, higher levels of education, more people reading newspapers and other media, and simpler access to transportation.

Slavery and the unfair treatment of women in society were two of the ills that reformers sought to eradicate at this time. Some reformers were extremely reasonable in their acts, while others employed impractical methods to make their points.

Some people didn't want to solve a problem completely; instead, they wanted to make some small adjustments that would make the parties involved happier while still having just a tiny effect on their life.

A lot of reformers had similar ideas about what a better world might look like. The majority of reformers favored treating all individuals equally, regardless of their ethnicity or gender.

They worked to ensure that everyone had the same rights as the white men at the time. Additionally, some reformers sought to improve working conditions, which prompted the creation of labor unions as a solution.

The majority of reformers shared the desire for a world with little violence as a common goal. They worked to spread their views and get people to understand that the world would be a better place if there was less violence, which is actually true.
