an outward fold of the surface of the cerebral cortex

Answers

Answer 1

An outward fold of the surface of the cerebral cortex is known as a gyrus (plural: gyri).

The cerebral cortex, the brain's outermost layer, is in charge of higher cognitive processes like perception, memory, language, and judgment. Numerous folds and grooves increase the cortex's surface area, enabling for more neurons and connections to be made in a smaller amount of room.

Gyri are the elevated ridges or folds on the cerebral cortex's surface. They are frequently divided by grooves known as sulci (plural: sulcus). Gyri and sulci are arranged in a certain pattern that is individual to each person and aids in increasing the cortex's surface area.

The cerebral cortex's folds and convolutions are crucial for allowing a greater number of neurons, facilitating complex information processing, and maximizing the brain's powers within the constrained space of the skull.

What are the characteristics that make people with psychopathic personality traits successful in business?

Answers

Psychopaths are more likely to gain power through dominance, bullying and intimidation, rather than respect.

Psychopaths are often considered to be charming, engaging and smooth, due to a lack of self-consciousness which frees them from the inhibitions and worries about saying the wrong thing that can cause others to be more socially awkward.

Psychopaths have a tendency to engage in risky behaviour without thinking of the consequences. This impulsivity comes from a lack of fear, according to criminal psychologist David Lykke.

It is commonly thought that psychopaths don’t feel any guilt or remorse, but recent research shows they are capable of such negative emotions, but only when something impacts them directly. In other words, if they hurt someone else, they won’t be racked with guilt like someone else might, but if a situation leaves them worse off financially, for instance, they may feel regret. Psychopaths know intellectually what’s right and wrong, but they don’t feel it, as one expert puts it.

Another key characteristic of the psychopath is that they mostly form superficial, short-term relationships with others, before casually discarding them.

Answers

What is protein ?

Amino acids make up the macromolecules known as proteins. Along with carbohydrates and fats, they are one of the three basic macronutrients needed by the body.

Age, sex, and amount of exercise are just a few of the variables that can affect the Recommended Dietary Allowance (RDA) for protein. I can give you a rough framework, though.

The RDA for protein for adult women is roughly 0.8 grams per kilogram of body weight. A 48 kg woman's protein needs would be determined by multiplying her weight by the suggested factor.

0.8 g/kg × 48 kg = 38.4 g

What is a hiccup ????

Answers

A hiccup, also known as singultus, is an involuntary contraction or spasm of the diaphragm muscle. The diaphragm is a large muscle located between the chest and the abdomen that plays a crucial role in breathing. When the diaphragm contracts unexpectedly and rapidly, it causes a sudden intake of breath, followed by a closure of the vocal cords. This results in the characteristic "hic" sound.

Hiccups can occur for various reasons, including eating or drinking too quickly, swallowing air, sudden changes in temperature, excitement or stress, certain medical conditions, or irritation of the nerves that control the diaphragm. While hiccups are usually harmless and resolve on their own within a short period, they can sometimes persist for longer durations or become chronic, requiring medical attention.

There are various home remedies and techniques to stop hiccups, such as holding one's breath, drinking water, or breathing into a paper bag. However, if hiccups persist for an extended period, interfere with daily activities, or are accompanied by other symptoms, it is advisable to consult a healthcare professional for evaluation and potential treatment.

Chapter 1.1 Real People: Nelson Mandela INSTRUCTIONS: Read the Real People feature from this chapter below, then answer the question that follows. Real People: Few people have had the breadth of lifetime experiences or the impact on their native country that Nelson Mandela did. Born on July 18, 1918, Mandela was the first member of his family to attend a school, eventually earning his bachelor's degree at the University of South Africa. In 1948, he began his political career by opposing the Afrikaner- dominated National Party, which supported the apartheid policy of racial segregation. It was a decision that changed his life. Mandela was initially dedicated to nonviolent opposition and was influenced by Mahatma Gandhi, who had begun his efforts at social activism in South Africa years earlier. However, after Mandela's arrest for treason in 1956 and his subsequent five-year trial (he was acquitted), he changed his view about nonviolent opposition. The Sharpeville Massacre in 1960, in which 69 peaceful protesters were killed by South African police, convinced him that armed struggle was now necessary to overthrow the apartheid government. So in 1961, he formed the armed wing of the African National Congress and began a guerrilla campaign of sabotage against military and government targets. Mandela was arrested again in 1962. This time he was convicted of sabotage and treason and sentenced to life imprisonment. He remained in jail until February 11, 1990, when he was released by President F. W. de Klerk. During a speech immediately after his release, Mandela said that his main focus was to bring peace to the black majority and give them the right to vote in both national and local elections. Between 1990 and 1994, he negotiated the first multiracial elections in South Africa's history. Mandela was elected president and served from 1994 to 1999. He helped the country move from white minority apartheid rule to a multiracial model of government built on reconciliation. His support of the Springboks rugby team that won the 1996 world title was especially important and was the subject of the 2009 film Invictus. After his retirement in 1999, Mandela remained politically active. He became an advocate for human rights organizations and in the fight against AIDS. He founded three organizations: the Nelson Mandela Foundation, the Nelson Mandela Children's Fund, and the Mandela Rhodes Foundation. Nelson Mandela was a true world leader, a person who reshaped the history of his country. He showed continuity in his life through political activity, perseverance through great hardships, and finding a balance between his personal competence and the challenges he experienced during his life. At his death in 2013, he was remembered for his unique ability to keep the focus on his cause justice while moving from a very activist approach to one emphasizing healing and trust. Consider the progression of Nelson Mandela from nonviolent protester, to outspoken activist, to national healer. Which forces in the biopsychosocial framework do you think were most influential in his evolving view of justice? a. Biological and sociocultural b. Life-cycle and sociocultural c.
