Why does your heart never tire of constantly beating to pump blood throughout your body

Answers

Answer 1
Its a myth that your heart never gets tired. While your heart certainly doesn't get fatigued the way your skeletal muscles do, it isn't impervious to fatigue or excess stress, such as from long distance, endurance-type cardio exercise. Your heart pumps about 5 quarts of blood per minute when you're sitting.

How were the atomic bomb attacks on japan during world war 2 an example of total war?

A. They were meant to wipe out as much of Japan's population as possible

B. They were used to attack civilian centers rather than military targets

C. They were made possible by the work of scientists not generals

D. They were used despite objections from international organizations

Answers

The answer is B. The atomic bombs that the United States dropped were the Fat Man and the Little Boy. They were dropped on Hiroshima and Nagasaki and killed about 146,000 in Hiroshima and 80,000 in Nagasaki. These bombs were made to push Japan to it's breaking point for it to surrender.

Answer:

B. They were used to attack civilian centers rather than military targets.

Explanation:

The concept of total war is used in political science and international relations in order to describe a type of warfare in which all infrastructure and resources, including civilian ones, are considered legitimate military targets. Moreover, a country engaged in a total war will give priority to military concerns over any others. This was the case of the attack on Japan during WWII, as Hiroshima and Nagasaki were cities with millions of civilians, and not military targets.

The battle cry made famous by the massacre at the mission in texas was "_______ "

Answers

The Alamo. I hope this helped you

The famous battle cry from the Texas Revolution is "Remember the Alamo!" It served as a rallying point for Texan troops seeking revenge and victory after the massacre at the Alamo mission.

The battle cry made famous by the massacre during the Texan struggle for independence from Mexico is "Remember the Alamo!" This phrase commemorates the Battle of the Alamo, where Texans, including iconic figures like Davy Crockett and Jim Bowie, fought against the much larger Mexican army led by General Santa Anna. The Mexican forces eventually prevailed, leading to the deaths of nearly all the Texan defenders.

Despite the tragic defeat, "Remember the Alamo!" became a rallying cry for the Texan army, providing motivation for revenge and ultimate victory. This battle cry was infamously shouted during the subsequent Battle of San Jacinto, which saw Sam Houston leading the Texan troops to a decisive victory over the Mexican army, capturing Santa Anna and securing Texas' independence.

What convinced the Soviet Union that it would not receive the reparations it wanted?

Answers

The correct answer is when west Germany was formed

The Soviets wanted all of Germany but since they couldn't have it they saw what the western forces did to Western Germany and how it was a capitalist country and they understood that they would not get reparations as long as they were a communist country and that they were perceived as a threat. This is why they locked Eastern Germany completely away with strong borders.

Final answer:

The Soviet Union realized it would not obtain the desired reparations due to refusal by the Western Allies to meet their demands, the exclusionary nature of the Marshall Plan, and the outcomes of postwar conferences which favored the reconstruction of a democratic Germany.

Explanation:

The Soviet Union was convinced it would not receive the reparations it wanted due to several factors. Conflict arose between the Soviets and the Western Allies, as the Western powers sought to rebuild a democratic Germany and refused Soviet demands for reparations from their sectors. Additional tensions were exacerbated by the Marshall Plan, which the Soviets perceived as exclusionary due to its focus on non-Communist nations, leading the Soviet Union to feel sidelined in postwar reconstruction efforts. Moreover, the Soviets had to postpone their demands for reparations following the Yalta Conference, and with the division of Germany, they lacked leverage to extract the desired compensation from the more economically robust Western sectors.

How is Caesar assassinated? The Tragedy of Julius Caesar by William Shakespeare: Act 3.1

Answers

Well... Historically speaking. Julies Caesar was murdered by members of his own court stabbing him. In regards to the William Shakespeare performance, I do not know... I would say it is the same.

In Shakespeare's 'The Tragedy of Julius Caesar', Caesar's assassination occurs in Act 3.1 where he is stabbed to death by senators led by Brutus and Cassius on the Ides of March.

In William Shakespeare's play The Tragedy of Julius Caesar, Caesar is assassinated in Act 3.1. A group of about sixty senators, feeling threatened by Caesar's accumulation of power and fearing he would make himself a king, conspire against him. Brutus and Cassius spearhead this conspiracy. On the Ides of March, March 15th, 44 BCE, they strike during a Senate meeting, where Caesar is stabbed to death. Notably, this act does not revive the Republic as the conspirators intended. Instead, it precipitates further chaos and the eventual rise of Caesar's adopted heir, Octavian.

Well the French Revolution occurred in the late 18th century, so it is possible it is referring to that when it says it was built upon the backs of the common man. During the 18th century, there was massive discontent with King Louis XIV, whose son (Louis XVI) eventually became King and also eventually became massively unpopular.

Because of the high taxes levied by the king, it was the common man who took part in the French Revolution. Therefore, the average man paid a high price for the French people's apparent greatness.

The cost function for Marisa's new clothing store where she sells T-shirts is C = $9.75n + 1025. What will Marisa's total costs for this month be if she sells 45 T-shirts this month?

Answers

Here is the answer ;)

Answer:

The total costs for this month is $1463.75

Explanation:

Consider the provided cost function.

It is given that the cost function for Marisa's new clothing store where she sells T-shirts is C = $9.75n + 1025.

Here, n represents the number of T-shirts Marisa sells.

We need to find the Marisa's costs if she sells 45 T-shirts this month.

To find this substitute the value of n=45 in the above cost function.

[tex] C = 9.75(45) + 1025[/tex]

[tex] C = 438.75+ 1025[/tex]

[tex] C = 1463.75[/tex]

Define the concept of unalienable rights. provide examples. 168. what is the purpose of the privileges and immunity clause that is located in the constitution? how did the supreme court interpret this clause in the infamous dred scott decision?

Answers

Unalienable rights are abilities that people have that can never be taken away from them by a government.  In the Declaration of Independence, the US outlines these unalienable rights as the right to "life, liberty, and the pursuit of happiness."

The privileges and immunities clause is supposed to help protect citizens from one state when they go to a different state. This prevents discrimination.

In the Dred Scott case, the Supreme Court ruled that Dred Scott (who is a slave) is considered property. That means he has no legal rights and is not protected by this clause, even though he lived in a free territory with his owner.
