how does the realists view US-China trade wars? what is their view on this issue?

Answers

Answer:

Let's start by defining realism. Realism provides an explanation for the state of war and the rise and fall of great powers. These themes include national sovereignty, security, survival, interests, the balance of power, and so forth. China and the U.S. have had a love and hate relationship. These included commercialism, imperialism, the dominance to confrontation, and finally, economic competitors in the present day. China's GDP is second to the United States. Therefore, both countries are economic hegemons, in other words, both have a strong influence on the world stage. Both react with tariffs and the other reacts by restricting its products. In this sense, they are reactionary forces at play.

Which of the following makes the most sense when it comes to the evolution of primates?
1 point
Humans and chimpanzees do not have similar DNA because they are no closer related to each other than any other animal on the planet
Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor
Humans and Chimpanzees have similar DNA because Humans evolved from Chimpanzees.
Humans and chimpanzees do not have similar DNA because they share a common ancestor.
The similarity of DNA between two species has nothing to do with how closely they are related.

Answers

The correct answer is Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor.

Explanation:

Both humans and chimpanzees are primates; this means both species belong to the same biological order (rank in taxonomy). Moreover, humans and chimpanzees share most of their DNA (around 99%). This indicates the two species are related and they evolved from the same ancestor. This implies a primate that existed million years ago (common ancestor) was the origin of these two species and due to this common ancestor they share most of their DNA; however, as both species changed separately the remaining DNA is different and this makes both species look and be different. According to this, the correct statement about the evolution of primates is "Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor."

Answer: Humans have 728 more pieces of DNA than chimpanzees have. This distinction may help evolutionary scientists understand the genetic characteristics that make humans different from chimpanzees. It may also explain how humans and chimpanzees evolved into two different species.

Why is school better than virtual learning? I need five sentences ir more plz ❤️

Answers

Answer:

School is better than virtual learning because you have better one on one connection. With virtual learning, you have to email your teacher and pray she emails you back in time. Though with brick and mortar school, you can walk right up to your teacher and ask for help as you are working. Also, normal school is better because you won't have to worry about internet connection and if your computer is 'compatible'. With virtual learning, you may have to wait a while as your computer loads, but in real school, you have immediate help to all your needs.

Answer:

In school is better because children need to learn how to socialize and not be anti-social. Things get done its easier (like cheating) and, get away with anything at all. Also, kids may not have the things that are required to do virtual learning like internet/wifi, a desk to write on, or even nice clothing to show themselves in. In school gets you the help you right away with virtual school teachers may get back to students days and days later...

How might evolutionary psychology explain how genetics and environment interact to
create alcoholism? In your explanation, include the role and importance of each of the
following factors.
1. DNA
2. Active genes
3. Family environment
4. The mind-altering impact of alcohol
5. epigenetics

Answers

Answer:

Its a lot but it should help

Explanation:

Adolescent alcohol use and behavior problems are influenced by both genetic and environmental factors. New findings show that behavioral problems may represent an earlier manifestation of a genetic predisposition to subsequent alcohol problems.

DNA is vital for all living beings – even plants. It is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organism's or each cell's development and reproduction and ultimately death.

Signals from the environment or from other cells activate proteins called transcription factors. These proteins bind to regulatory regions of a gene and increase or decrease the level of transcription.

The family environment is important in that children are taught what types of transactions are considered appropriate. They learn to form relationships, handle power, maintain personal boundaries, communicate with others and feel that they are an important subset of the whole family system.

Difficulty walking, blurred vision, slurred speech, slowed reaction times, impaired memory: Clearly, alcohol affects the brain. Some of these impairments are detectable after only one or two drinks and quickly resolve when drinking stops.

These mechanisms comprise DNA and chromatin modifications and their associated systems, as well as the noncoding RNA machinery. The epigenetic apparatus is essential for controlling normal development and homeostasis, and also provides a means for the organism to integrate and react upon environmental cues.

Psychology explains that genetics and environment influence alcoholism as what we see from childhood, our behavior is modified as it.

What is alcoholism?

All living things, including plants, depend on DNA. DNA / Active genes- It is crucial for heredity, protein-coding, and the genetic manual for life and its functions. Proteins known as transcription factors are activated by signals from the environment or from other cells.

Family environment - They gain the ability to interact with others, build connections, manage authority, uphold personal boundaries, and feel like an integral part of the larger family structure. The mind-altering impact of alcohol.

Thus, the epigenetic apparatus is crucial for maintaining homeostasis and appropriate development, as well as giving the organism a way to take in and respond to environmental cues.

Proposition of value

What is Education?

Education is a planned activity with certain goals in mind, such as knowledge transmission or the development of skills and character. These objectives might include the growth of comprehension, reason, kindness, and honesty.

For the purpose of separating education from indoctrination, numerous studies emphasize the importance of critical thinking. While some theorists insist that education must lead to a student's improvement, others favor a definition of the term that is value-neutral.

In a slightly different sense, education can also refer to the mental states and dispositions that educated people possess, rather than the practice itself. The original purpose of education was to pass on cultural heritage to future generations.

What problems did Chinese aristocracy cause

Answers

Like earlier emperors, Tang rulers relied on a large bureaucracy. Officials collected taxes and oversaw building and irrigation projects. They managed the army and enforced the laws. But how could emperors be sure that they chose the best people for these positions?

Earlier emperors answered this question in different ways. Before the Han dynasty, emperors chose members of the aristocracy to help them govern. These people were born into noble families of wealthy and powerful landowners. But simply being wealthy did not make a person talented and knowledgeable.

To improve the bureaucracy, Han emperors created civil service examinations. Candidates took long tests to qualify for office. The tests had questions on Chinese classics, poetry, and legal and administrative issues. Mainly, they were based on the works of Confucius (kon-FEW-shus), China’s great philosopher and teacher. This began the system under which a class of scholar-officials ran the government.

Later, Tang emperors also used civil service exams to fill some government positions. Early in the dynasty, however, emperors chose aristocrats for most high-level jobs. Some officials were hired because their fathers or grandfathers had held high government rank. Some were hired because of personal recommendations. Often, aristocrats gained positions by marrying into the imperial family.

Even the civil service exams favored aristocrats. The tests were supposedly open to all except for certain groups, such as merchants, actors, and beggars. In theory, any man could attend the university where students prepared for the exams. In reality, however, only the wealthy could afford tutors, books, and time to study. As a result, aristocrats held almost all offices in the early part of the Tang dynasty.
