Answers

Since plants convert carbon dioxide and grow because of the carbon it helps the plants and when that happends where there are plants there is more air produced for us to breath.It can also change the climate because of the levels of air that is produced by plants is in the  atmosthphere.So they know because there is more air and because where there are plants there is more fresh air to breath.Also plants take the carbon dioxide and clean the carbon in the air causing us to breath good air.

"Anyone who was a British subject in South Africa and wh was not a European". Do you think this is a good definition for 'coloured'? Give reasons for yoir answer.

Answers

The correct answer to this open question is the following.

I think that this definition can be improved to something like this.

In British South Africa times, coloured people could be considered the people born from one English father/mother, and the other from a black native South African. So these people were British subjects who had missed ancestry in their blood. Half of them were African and the other half was from Europe. This is a better definition.

In times of the British presence in South Africa, the term "coloured" was seen as a social category instead of being understood as a legal term. Most of these coloured people used to live in Cape Town, and were considered educated Christians.

How do people think about socialism vs. capitalism in the US? Please help!

Answers

Answer:

Explanation:

most people think that socialism defies the point of the us because it was built on capitalism but there are a few  people who think      

Answer:

.

Explanation:

For many Americans, “socialism” is a word that evokes a weakened work ethic, stifled innovation and excessive reliance on the government. For others, it represents a fairer, more generous society.

Critics of socialism point to Venezuela as an example of a country where it has failed. People with positive views of socialism cite different countries, such as Finland and Denmark, as places where it has succeeded.

‘Capitalism’ viewed positively by about two-thirds of Americans

Among the 65% with a positive view of capitalism, many give reasons that contrast with criticisms of socialism. For example, while many who hold a negative view of socialism say it undermines initiative and makes people too dependent on government, nearly a quarter of those with a positive view of capitalism say it promotes individual opportunity (24% say this).

And while those with a positive view of socialism say it could bring increased equality, a common theme among critics of capitalism is that it has led to unequal distribution of wealth in this country

For the heredity Test, we assumed that crossing a short-furred FF female with a short-haired F male would produce only offspring with short hair. We found a 1:0 phenotypic ratio in the data chart, which indicates that all offspring had short fur. This backs up the theory.

What is Heredity?

The term "inheritance" describes the transmission of qualities from one generation to the next via genetic material, such as DNA. It is the process through which genetic information is passed from one generation to the next and is essential for the growth of both individuals and groups.

Different physical and behavioral qualities, including height, eye color, hair color, predisposition to certain diseases, and others, are inherited due to heredity.

Our research backs up the Mendelian inheritance theory, which states that the dominant allele suppresses the expression of the recessive allele. We discovered that the hamsters' inheritance of fur length followed the ratios predicted by inheritance laws. Our findings back up the theories put out in each of the experiments.

Therefore, short fur, FF female and short fur, F male are the test variables.

When Spanish conquistadors began their conquest of South and Central America, they met very little resistance from the Maya civilization there. Why were the Maya so easy for the Spanish to defeat?

A: The Mayas had joined the Incas in the mountains of South America, centuries before the Spanish arrived.

B: The Mayan culture and population had been weaked by a long-lasting and severe drought, centuries before the Spanish arrived.

C: The Mayas were a peace-loving people who were not willing to fight back against the Spanish mercenaries.

D: The Mayas had been defeated by the Aztecs and absorbed into their culture, a century before the Spanish arrived.

Answers

Answer:

Mostly B althoguht the correct answer is that Spanish conquistadors had much more advanced weapons and horses

Explanation:

The region, in which Mayas were living, suffered from long-lasting and severe drought centuries before the Spanish arrived.

Who are Mayas?

The Mayas were an indigenous civilization that flourished in Mesoamerica, in what is today in modern-day Mexico, Guatemala, Belize, Honduras, and El Salvador.

The Maya civilization emerged around 2000 BC and reached its climax between 250 AD to 900 AD. The Mayans had developed a sophisticated culture, known for its advances in writing, mathematics, astronomy, architecture, and art.

The Maya region suffered a long severe drought which led to the depletion of agriculture and other allied activities. It also led to food shortages which caused civil unrest which weakened the Mayans.

This severe drought caused multiple problems for the Mayans, which in turn helped the Spanish conquistadors in their conquest as they faced a weak Mayan civilization.

Hence, Option (B) is correct.

What happened to China's economy during the Great Leap Forward?
O The economy went backward.
The economy moved ahead.
O The economy was modernized.
The economy stayed the same.

Answers

The economy went backwards!

China's economy during the Great Leap Forward went backward. Thus the correct option is A.

What is the Economy?

Every nation's economy is based on the ratio of its annual output to its annual consumption, which also assesses the flow of money into the market by looking at each person's purchasing power.

The quick conversion of China from an agricultural to an industrial society was the goal of the social and economic campaign known as "The Great Leap Forward" in China.

The Great Leap Forward caused drought and widespread starvation instead of boosting the nation's economy. This campaign's goal is to demonstrate how collective farms can coordinate labor more effectively, cut down on inefficiency and waste, and significantly boost output.

Therefore, option A is appropriate.
