When acetylcholine binds to receptors at the motor end plate, the sarcolemma becomes?.

Answers

Answer 1

When acetylcholine binds to receptors at the motor end plate, the sarcolemma becomes more permeable to sodium ions and sodium ion channels open and sodium rushes into the muscle.

Acetylcholine refers to the neurotransmitter (chemical messenger working for the brain) found at neuromuscular junctions, at synapses in the ganglia of the visceral motor system and at a variety of sites within the central nervous system. Its main function is to trigger the firing of motor neurons and to cause voluntary movements. The lining over muscle fibre is called sarcolemma. It enables transportation of material across the muscle cells and transmits neural signals which cause excitation or contraction of muscle. When sarcolemma is excited, muscle is said to be in active state while when it becomes impermeable to sodium ions, it is said to be in resting mode.

Identify a true statement about the work of Andrew Meltzoff on imitation in infant development.
Multiple Choice
He holds that deferred imitation does not occur until about 18 months of age.
He emphasizes that an infant's imitative abilities resemble a hardwired response.
He has concluded that infants blindly imitate everything they see.
He sees infants' imitative abilities as biologically based.

Answers

The true statement about the work of Andrew Meltzoff on imitation in infant development is that he sees infants' imitative abilities as biologically based.

Andrew Meltzoff is a developmental psychologist who has studied infant imitation extensively. He has shown that very young newborns, as young as two or three months old, can imitate simple facial expressions and gestures.

According to Meltzoff, this ability to imitate is biologically founded and serves as a basis for later learning and development.

Meltzoff has also emphasised that newborns' imitative abilities are not merely hardwired reflexes, but rather reflect an active and flexible learning and exploring process.

He has demonstrated that newborns can perform selective imitation, in which they choose to copy specific acts or behaviours that are most relevant to their aims or interests.

What is Gross domestic product?

A monetary indicator of the market worth of all the finished products and services produced in a nation over a certain time period is called the gross domestic product. This measurement is frequently reviewed before being regarded as a valid indicator due to its subjective and complicated character. While nominal gross domestic product is more useful for comparing national economies on the global market, GDP (nominal) per capita does not account for variations in the cost of living and inflation rates of the various nations. As a result, using a basis of gross domestic product per capita at purchasing power parity (PPP) may be more useful when comparing living standards between nations.

Answers

When Americans recognize that people are born into a particular social position due to the economic situations of their families, they are recognizing the existence of social and economic inequality.

Acknowledging that individuals' social position is influenced by the economic circumstances of their families reflects an awareness of social and economic inequality. It highlights the recognition that not all individuals start on an equal footing and that access to opportunities and resources can be shaped by socioeconomic factors.

This understanding aligns with the concept of social mobility, which refers to the ability of individuals to move up or down the social ladder based on their own merits and efforts. Recognizing the role of economic situations in determining social position emphasizes the need to address systemic barriers and create a more equitable society. It prompts discussions about issues such as wealth and income disparities, educational access, and social mobility, as well as policies and interventions aimed at reducing inequalities and promoting equal opportunities for all individuals, regardless of their family backgrounds.

president john tyler obtained approval for the annexation of texas. (True or False)

Answers

The statement "President John Tyler obtained approval for the annexation of texas" is True.

President John Tyler did obtain approval for the annexation of Texas. In 1844, Tyler, who was the 10th President of the United States, signed a treaty of annexation with the Republic of Texas. However, the treaty faced opposition in the United States Senate and failed to gain the required two-thirds majority for ratification.

Despite the setback, Tyler and his administration pursued other means to secure the annexation of Texas. In 1845, shortly before leaving office, Tyler signed a joint resolution passed by both houses of the U.S. Congress, which provided for the annexation of Texas as a state. The resolution required a simple majority for approval, and it was successfully passed and enacted. On December 29, 1845, Texas was officially admitted to the United States as the 28th state.

Therefore, President John Tyler played a crucial role in obtaining approval for the annexation of Texas, despite facing initial challenges in the form of the failed treaty.

According to purchasing-power parity, inflation in the united states causes the dollar to.

Answers

According to purchasing-power parity, inflation in the United States causes the dollar to lose value.

According to the purchasing-power-parity (PPP) theory, inflation in a country causes its currency to depreciate relative to other countries' currencies. This is because as the general price level in a country increases, the currency's purchasing power decreases, making it less valuable in comparison to currencies of other countries where prices have remained relatively stable.

Thus, inflation in the United States would cause the dollar to depreciate relative to other countries currencies, all else being equal. This would result in higher prices for U.S. imports, while U.S. exports would become more competitive and less expensive for foreign buyers. This means that the purchasing power of the dollar decreases, making it more expensive for consumers to buy goods and services both domestically and abroad. It also makes imports more expensive, potentially leading to a decrease in international trade and a reduction in the country's competitiveness.

What does Herzberg's theory say about motivation?

Answers

Herzberg's theory states that motivation in the workplace is influenced by two sets of factors: hygiene factors and motivators.

According to Herzberg's theory of motivation, hygiene factors are external factors in the work environment that, when lacking, can lead to job dissatisfaction. These factors include salary, job security, working conditions, company policies, and interpersonal relationships. While the presence of hygiene factors may not necessarily motivate individuals, their absence can create dissatisfaction and hinder motivation.

On the other hand, motivators are internal factors that contribute to job satisfaction and intrinsic motivation. These factors include recognition, achievement, responsibility, growth opportunities, and the nature of the work itself. Motivators are seen as the primary drivers of job satisfaction and can lead to higher levels of motivation, engagement, and productivity.

Which system opened in 1819 and divided its inmates into three classes with the most difficult inmates placed in solitary confinement

Answers

The system that opened in 1819 and divided its inmates into three classes with the most difficult inmates placed in solitary confinement was the Auburn System.

This correctional system was implemented at Auburn Prison in New York, USA, and became influential in the development of modern penitentiary systems. Under the Auburn System, inmates were organized into three classes based on their behavior and level of cooperation. The first class consisted of well-behaved prisoners who were allowed more privileges and were employed in various prison industries.

The second class included inmates with minor disciplinary issues, who had more restrictions and were subjected to a stricter regimen. The third class comprised the most difficult and dangerous inmates who were placed in solitary confinement as a means of punishment and control. Solitary confinement in the Auburn System was intended to induce reflection, penitence, and ultimately, reform.

Inmates were isolated in small cells for most of the day, with limited human contact and strict silence. This system aimed to enforce discipline, prevent communication between prisoners, and create a sense of remorse or regret in the incarcerated individuals. While the Auburn System had some positive effects in terms of maintaining order and discipline within the prison, its use of prolonged solitary confinement has been heavily criticized over time.

Studies have shown that long periods of isolation can have severe psychological and emotional consequences, and many argue that alternative approaches to rehabilitation and punishment should be pursued.

Rock picking is a yearly ritual that every midwestern farmer in the US has to perform on their farm. Even if the farm has been plowed freshly, there is a possibility of rocks emerging.

Plowing aerates the soil, bringing wet soil on top, and bringing along rocks lying in the soil bed underneath.

As per farmers in Minnesota and their neighbor Wisconsin, large boulders are harmful to their farming machinery. These rocks need to be removed often by hand.

Thus, every year, before sowing, the farmers and their families get together to pick rocks from the farms.

These rocks keep remerging over the ground every year mostly due to the frost heaving or bringing them up from the earth.
