After her sunlight experiment, Mary observes that the plants in her garden grow when she waters the soil. She wonders if the plants would grow with the same amount of water, but no soil. Using the steps of the scientific method, explain how Mary would conduct a science experiment to test whether plants need soil to grow.

Answers

Answer 1

Mary would start with a hypothesis such as, "I believe that plants with no soil will not grow because there are no nutrients coming from the soil for the plant to grow"

Then she would put the plan in place to start her experiment. She will get the same type of seeds, the same amount of water and sunlight. The only difference between the 3 plants is that one plant will have no soil, the second plant will have 1 inch of soil, the third plant will have the correct amount of soil.

She will run the experiment for 2 weeks to see whether the plants have grown and what the conclusion is. She will record how much the plants have grown every day, she will measure the height of each plant.

At the end of 2 weeks, she will gather all her data and come to a conclusion.

Answer 2

Answer:

Mary would use the steps in the scientific method to determine if the plants need soil to grow. She would carry out the steps in the following order:

Make observations: The plants in the garden grow when the soil is watered.

Ask questions: Mary wondered about the presence of soil and asked, Would plants grow even if they weren’t in soil?

Construct the hypothesis and make predictions: Mary hypothesized that plants need only water to grow, but not soil. So, she predicted that a plant put in water instead of soil would still grow.

Test the hypothesis: She put two identical plants in two different boxes: one box with soil and one box with water. Then she placed them in the same amount of sunlight. She added the same amount of water to both boxes each week. Finally, she measured the height of both plants at the start and end of the experiment.

Analyze the results and make a conclusion: At the end of two weeks, Mary measured both plants to determine if they grew. The plant with water grew less than the plant with soil. She concluded that plants need soil, water, and sunlight to grow. Soil contains essential nutrients. When the plant receives sunlight, the water carries these nutrients to various parts of the plant, allowing the plant to grow.

Explanation:

World War I proved to be the decisive break with the old world order, marking the final demise of absolutist monarchy in Europe. It would prove the catalyst for the Russian Revolution, which would inspire later revolutions in countries as diverse as China and Cuba, and would lay the basis for the Cold War standoff between the Soviet Union and the United States. The defeat of Germany in the war and failure to resolve the unsettled issues that had caused the Great War would lay the basis for the rise of Nazism, and thus the outbreak of World War II in 1939. It also laid the basis for a new form of warfare that relied heavily on technology, and would involve non-combatants in war as never before.

what did some southern states require from african american voters

Answers

The Southern states, even after slavery was abolished, still held a grudge towards African Americans. They even ended up enacting numerous functions to stop the voting of African Americans, as they thought that if they voted, they would vote for someone that wanted equality. Southerners wanted to keep African Americans oppressed and keep control of the office.

One of the things that the Southern states would do would be literacy tests, as African Americans often did not have the chance to obtain education, many did not know how to read or write. A good amount of African Americans would fail the literacy tests and could not vote.

Poll taxes were another huge thing that kept African Americans from voting, as many did not have a lot of money to spare, as discrimination was still present among workplaces, so they would not make the same amount of money as a white man, so this also kept African Americans from voting.

In 1870, the 15th Amendment was finally ratified, which made it so men of any race could vote freely and not be discriminated against.

In Korematsu v. the United States, the Supreme Court ruled that the internment of Japanese Americans was illegal. True False

Answers

Final answer:

The Supreme Court's ruling in Korematsu v. the United States on December 18, 1944, was false; the court upheld the internment of Japanese Americans as a wartime security measure and not until 1983 was Korematsu's own conviction reversed.

Explanation:

The statement that the Supreme Court ruled the internment of Japanese Americans was illegal in Korematsu v. the United States is false. In fact, the Supreme Court decision on December 18, 1944, upheld the government's decision to intern Japanese Americans. This ruling was one of the most controversial, as it supported the government's actions as a security measure during wartime despite impacting the constitutional rights of U.S. citizens. It wasn't until much later, in 1983, that Fred Korematsu's individual conviction was eventually overturned by a federal court based on new information showing an absence of Japanese American espionage. The Supreme Court's stance on internment effectively remained unchanged until it was renounced in the context of a separate case in 2018, where the Korematsu decision was acknowledged as wrong, highlighting the actions of internment as gravely mistaken.

Answer: The answer is D

Explanation: Wilson's "Fourteen Points" were his ideas for the world after World War I. His goals were laid out in this document. The ultimate goal was to maintain a peace amongst all nations in order to prevent another world war.

Even though the League of Nations never lives up to its promise, it does set the groundwork for the United Nations (which still exists today).

Negative term for a business magnate implying that the Tycoon used unethical means to acquire Fortune

Answers

Answer:

Negative term for a business magnate implying that the Tycoon used unethical means to acquire Fortune is "Robber Barron".

Explanation:

"Robber baron" is a stereotypical term of social criticism typically attributed to certain American entrepreneurs of the late 19th century who have been convicted of using unethical tactics to enrich or increase their fortunes.

The concept was focused on a comparison with the German robber barons, regional feudal lords or robbers in Germany who were owed some tax or fine to the waylaid travelers across their putative land. As early as 9th February 1859 the metaphor appeared. The word blends the derogatory senses of thief ("robber") and aristocrat ("barons" in a republic that have no useful role).

Public goods are accessible to all without direct charge, while some public amenities might have fees for certain services.

Hotels, restaurants, shops, public restrooms, and drinking fountains are all examples of services and amenities that are typically provided by private businesses in the economy. These businesses cater to the general public and can be found in numerous locations such as cities and tourist destinations. They contrast with other forms of goods and services, like public goods, which are usually provided by the government and available for use by the entire public, sometimes without direct charges.

Public goods are often funded by taxes and are available to all individuals regardless of whether they have contributed financially. Examples include public safety services, public schools and universities, public hospitals, public housing, and public transit systems like buses and subways.

Different from public goods are the public amenities, where access can be regulated through fees. For instance, a public city park might be free for everyone to enjoy, but there could be charges for parking, reserving picnic grounds, or purchasing food at a concession stand. This represents a mix of public provision with some additional user fees.
