using the word semi permeable, explain how a screen is similar to a cell membrane

Answers

Answer 1

Answer with Explanation:

A "screen" is semipermeable just like the cell membrane because it only allows certain tiny things to pass through. For example, an aircon protector filter screen allows the air to be ventilated into a room but not the contaminants coming from outside. These contaminants may include dirt, pollens, smoke, dust, etc. In a similar nature, the cell membrane only allows small particles to pass through just like oxygen.

Both the screen and the cell membrane act as barriers. Only certain things can diffuse readily through them while the other things are being trapped.

Why is it difficult to stop the practice of tavy farming in Madagascar? (Site 1)

Answers

It is hard to stop Tavy farming because the farmers need the land to plant food and provide for their familes. If they stop doing Tavy farming, they wont have enough food to survive and provide for them.      

I'm sorry if this answer is wrong I just tried to help the person who asked it, and I'm sorry for that other person her commented.  

Tavy works well and does not permanently destroy the forest as long as field sizes are small and farmers leave adequate time for re-growth. However, if you do this too much, too quickly soil starts to leak nutrients. It is hard to stop tavy farming because farmers in Madagascar are needing the nutrients for their crops; because they don't have enough money for fertilizers. So on without doing it, they could starve, but they are taking down trees and animal homes to do so, leaving a scar on the environment.

Answer:

Adult illiteracy isn't often spoken about compared to other subjects, but it is so important.

Explanation: Thousands of people today are struggling with reading because of their childhoods and where they live. A similar person that dealt with illiteracy was Amelia Sandoval. As a child her parents never valued education and she dropped out of school in fifth grade. Her childhood was a disaster and she wound up in jail. After getting straightened up, she realized how different of a life she should've lived and what she should change.  As soon as she got out of jail sandoval got an education, and knew that it was the first step to improve herself. Amelia isn't the only one struggling with illiteracy, and not everyone has access to knowledge. "I had no regular teacher"(Douglass 1). Just like Amelia, Frederick didn't go to school, he couldn't just get an education like we can today.

Briefly explain why obedience to the Roman Catholic pope was judged to be evidence of obedience to government rulers during Spanish domination of Latin America

Answers

Answer:

The Roman Catholic Pope and the governments that were allies had close ties and worked together for mutual interest.

Explanation:

During the period of colonization, the government rulers of Spain and the Roman Catholic Pope had very close ties. They basically collaborated and in many ways worked together for mutual interest. The mutual interest was basically to retain power and keep the obedience of the masses for that purpose.

If the people were obeying the Roman Catholic Pope, and the majority did, it was not just seen as a religious thing, but also as a political one. Automatically, the rulers of the Spanish empire accepted this as the people obeying them. While this may seem strange, it is not really, since the rulers of Spain had a big influence on the Pope and protected him, while the Pope was doing a double job, political and religious, in keeping people at peace.

Why is trade an essential part of the culture and economy of the Pacific Islands?

Answers

Answer: Trade spreads culture & ideas because it encompasses people who move around the globe while trading. ... Trade has bought has bought with it wealth as well as diversity.

Explanation:

Resources are unevenly distributed throughout the Pacific Islands, which makes trade vital to the region's economy. Trade is therefore essential for surviving. Trade, where subsistence farmers sell small quantities of agricultural goods, is a significant component of the informal economy.

Why trade is important?

Trade enables nations to access commodities and services that might not otherwise be accessible domestically as well as increase their markets.

Market competition has increased as a result of global trade. This ultimately leads to more competitive pricing, which lowers the cost of the final product for the consumer.

Trade is a growth engine that improves jobs, lowers poverty, and expands economic opportunities.

According to recent studies, trade liberalization boosts economic growth by an average of 1.0 to 1.5 percentage points, which after ten years results in income that is 10 to 20 percent greater.

Hence, the resources are unevenly distributed throughout the Pacific Islands, which makes trade vital to the region's economy. Trade is therefore essential for surviving. Trade, where subsistence farmers sell small quantities of agricultural goods, is a significant component of the informal economy.

А) It is the largest city in the Middle East.
B) Tripoli is located along the Mediterranean Sea.
C) Tripoli is the home to millions of devout Muslims.
D) It is located far from a major river or major desalinization plant.​

Answers

Answer:

D. It is located far from a major river or major desalinization plant.

Explanation:

"Tripoli" is Libya's capital city. If you happen to see the map, the city is located far from a major river or major desalinization plant. This is because, the place lacks in rainfall which makes it harder to form permanent rivers. Such problem clearly shows the need to address its access to groundwater.

"The Great Man-Made River" was made established in 1892 in order to address the water problem in the area. These pipelines supplies water to the different parts of Libya (including Tripoli).

Answers

Answer:

Correct answer is D) French and British​.

Explanation:

Option is D is the correct answer as British and French explorers were the first ones who came to the soil of Canada in late 15th and beginning of 16th Century. Later they have even fought for that land, and probably the most famous one was the French and Indian war in 1763 after which Canada went under control of Britain. Even today English and French are official languages in Canada.

A is not correct as Spain colonized mostly Central and South America.

C is wrong for the same reason - Portugal settled only in South America.

Expository, on the other hand, requires the writer to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner.

The percentage of water consumption that is not returned to the original water source after withdrawal is referred to as "water consumption." Water is consumed when it is evaporated into the atmosphere or integrated into a product or plant.

How can I write an essay about water?

Water is the most basic requirement for all life forms on Earth to function. It is safe to claim that water is the reason that Earth is the only planet capable of supporting life. This universal solvent is one of the most important resources on the earth. Life cannot exist in the absence of water.

Water aids in solid meal digestion. It also maintains the health and hydration of our skin. Water aids in the elimination of waste from our bodies via sweat, urination, and defecation. To prevent dehydration, we must replenish the water in our bodies.
