explain why market and government policies is very influential in the decision making process of a farmer​

Answers

Answer:

The answer is below

Explanation:

The market of a particular product can be explained as the whole aggregate of all the buyers and sellers in a given area or region. The information of the market tends to sway the farmer in deciding on which crops to produce in that particular area over a given period. More often than not, farmers are likely to plants or produce agricultural products whose supply gaps need to be fixed.

On the other hand, government policies such as subsidies, importation bans, climatic control, land use act, and many more, have a greater influence on farmers on which area of production to embark.

How did Lincoln explain the origins of the war? How was the Republican Party that he
represented implicated in the war's outbreak?

Answers

Answer:

As a war leader, Lincoln employed the style that had served him as a politician—a description of himself, incidentally, that he was not ashamed to accept. He preferred to react to problems and to the circumstances that others had created rather than to originate policies and lay out long-range designs.With the election of Abraham Lincoln (the first Republican president) in 1860, the Party's success in guiding the Union to victory in the American Civil War, and the Party's role in the abolition of slavery, the Republican Party largely dominated the national political scene until 1932.

How did the development of coined money change trade? (1 point)

Answers

Answer:

It allowed people to buy and sell goods in a wider market.

Explanation:

Before coined money people couldn't sell or buy things in a wider market. After the development of coins, people could use them to buy what they wanted and coins held their value for a very long time. Before coins, you had to trade something you had for something you need. If the other person didn't need what you were offering he would not take the offer to trade. But with coins that changed since the merchant always has a use for a coin when compared to a carrot.

4. How did the threat of the British joining the Confederacy factor into Abraham Lincoln’s decision to issues the Emancipation Proclamation?

Answers

Answer:

Explanation:

On September 22, 1862, President Abraham Lincoln issues a preliminary Emancipation Proclamation, which sets a date for the freedom of more than 3 million enslaved in the United States and recasts the Civil War as a fight against slavery.

When the Civil War broke out in 1861, shortly after Lincoln’s inauguration as America’s 16th president, he maintained that the war was about restoring the Union and not about slavery. He avoided issuing an anti-slavery proclamation immediately, despite the urgings of abolitionists and radical Republicans, as well as his personal belief that slavery was morally repugnant. Instead, Lincoln chose to move cautiously until he could gain wide support from the public for such a measure.

In July 1862, Lincoln informed his cabinet that he would issue an emancipation proclamation but that it would exempt the so-called border states, which had slaveholders but remained loyal to the Union. His cabinet persuaded him not to make the announcement until after a Union victory. Lincoln’s opportunity came following the Union win at the Battle of Antietam in September 1862. On September 22, the president announced that enslaved people in areas still in rebellion within 100 days would be free.

On January 1, 1863, Lincoln issued the final Emancipation Proclamation, which declared “that all persons held as slaves” within the rebel states “are, and henceforward shall be free.” The proclamation also called for the recruitment and establishment of Black military units among the Union forces. An estimated 180,000 African Americans went on to serve in the army, while another 18,000 served in the navy.

Give an example of an advance in medicine that came about during the Islamic Golden Age and explain how it had an effect on modern medicine.​

Answers

Answer:

Islamic doctors developed new techniques in medicine, dissection, surgery and pharmacology. They founded the first hospitals, introduced physician training and wrote encyclopedias of medical knowledge.

Early Islamic medical centers would be recognizable as hospitals today: they had wards for different diseases, outpatient clinics, surgery recovery wards and pharmacies. They also functioned as medical education centers for doctor training.

Islamic hospitals pioneered the use of antiseptics such as alcohol, vinegar or rose-water in cleaning wounds. Everything was to be kept as clean as possible.

Islamic pharmacies, called saydalas, began at the same time as the hospitals, in the late 700s, as part of the Islamic health care system.

This is a photo of the first mobile X-ray machine, an innovation created by Wilhelm Conrad Roentgen in 1895.

Roentgen's groundbreaking discovery revolutionized medical diagnostics by allowing doctors to visualize internal structures without invasive procedures. His invention of X-rays paved the way for countless advancements in the field of radiology.

Joseph Lister, on the other hand, was known for his significant contributions to the field of antiseptic surgery during the 19th century. Lister developed the concept of sterilizing surgical instruments and disinfecting wounds to prevent infection. His research and practices greatly reduced the mortality rate associated with surgical procedures and laid the foundation for modern aseptic techniques.

The first rabies vaccine, it was created by Louis Pasteur in the late 19th century. Pasteur's work on developing vaccines against various diseases, including rabies, marked a major breakthrough in immunology.

By successfully vaccinating against rabies, Pasteur demonstrated the concept of using weakened or attenuated pathogens to induce immunity and prevent infectious diseases, setting the stage for future advancements in vaccine development.

These three pioneers—Roentgen, Lister, and Pasteur—each made remarkable contributions to the fields of medical imaging, surgery, and immunization, respectively, leaving a lasting impact on the practice of medicine and improving the well-being of countless individuals worldwide.
