explain what it means to say that the earliest organisms were heterotrophic anaerobic prokaryotes.

Answers

Answer 1
Answer:

Heterotrophs, meaning "other feeders", are simply organisms that cannot make their own food. So "heterotrophic anaerobes" means they were creatures which ate some naturally occurring food and did not breathe oxygen. Hope this helps! :)
Answer 2

Heterotrophs are essentially organisms that cannot produce their own food, hence the name "other feeders." Therefore, "heterotrophic anaerobes" refers to organisms that did not breathe oxygen but instead consumed some naturally existing food.

What are heterotrophs?

Heterotrophs are defined as the organisms that are dependent on plants for their sustenance and are unable to create their own food by converting inorganic materials and light energy into organic materials. Photoheterotrophs and chemoheterotrophs are the two subgroups of heterotrophs.  Heterotrophs must consume or absorb their food because they are unable to produce it.

The earliest living things on Earth were bacteria. They first appeared in the first oceans' water three billion years ago. Initially, only anaerobic heterotrophic microorganisms existed.

Thus, heterotrophs are essentially organisms that cannot produce their own food, hence the name "other feeders." Therefore, "heterotrophic anaerobes" refers to organisms that did not breathe oxygen but instead consumed some naturally existing food.

How did German territorial losses lead to World War II?

The Soviets were angry about not receiving territory, leading to expansion attempts in Eastern Europe.
Ethnic divisions in Czechoslovakia caused conflicts between competing international alliances.
Germans resented losing territory to the new Poland, which fueled nationalistic tendencies.
French grievances about Germany’s nonpayment of war damages caused France to demand more land.

Answers

The correct answer is C) Germans resented losing territory to the new Poland, which fueled nationalistic tendencies.

German territorial losses lead to World War II in that Germans resented losing territory to the new Poland, which fueled nationalistic tendencies.

After losing World War I, German was forced to accept the terms of the Treaty of Versailles. As part of the peace treaty, Germany was forced to give territory to Poland, Belgium, and Czechoslovakia. Of course, Germany was forced to pay reparations for the damage caused during the war.

These factors and the fact that the Weimer Republic did not work out as expected, created the conditions for the rise of the Nazi Party and the arrival of Adolph Hitler as the leader of Germany in 1933.

Hint: use your objectives to help you.

Answers

The below labelings and explanations are what is requested:

The Labels and Explanations

Great Britain owned both colonies and settler colonies, for example India, Australia, Canada, and South Africa.

The resources procured from these places encompass tea, cotton, diamonds, and gold.

French colonies situated in Africa, Southeast Asia, and the Caribbean facilitated the collection of rubber, oil, coffee, and sugar.

German colonies located in Africa, Asia, and the Pacific led to the harvesting of rubber, timber, and diamonds. Italy's colonial ownership in Africa and the Mediterranean yielded cotton and coffee.

Spanish rule in Latin America and the Philippines acquired gold, silver, and sugar, whereas Portugal's authority in Brazil, Africa, and Asia provided gold, diamonds, and spices.

As per Belgium's possessions in Africa, including the Congo, they gained access to rubber and ivory. Japan had control over Korea and Taiwan reaping coal and iron as a result. Furthermore, economic imperialism took place in China, Iran, Mexico, and Ethiopia while anti-imperial resistance was witnessed in India's Indian Rebellion of 1857, China's Boxer Rebellion of 1899-1901, Africa's Mau Mau Uprising, and Cuba's Revolution of 1959.

the market for yam is in equilibrium ,show how the following events will affect the market. 1. Research has shown that eating more yam cut the risk of cardiovascular diseases. 2. there is an increase in the cost of fertilizer​

Answers

Answer:

Scenario 1 ⇒ Demand for yam will increase.

If people found out that eating yams reduced the risk of them getting cardiovascular diseases, they would demand more of it so they can benefit from this reduced risk.

This will lead to a rise in price because the Demand curve will shift to the right and intersect with the Supply curve at a higher equilibrium price.

Scenario 2 ⇒ Supply of yam will decrease.

With the cost of fertilizer increasing, farmers of yam will have to incur more cost to be able to produce yams. They will therefore reduce their production levels so that they incur less cost thereby decreasing supply.

This decrease in production levels will lead to a rise in price because the supply curve will shift to the left and intersect with the Demand curve at a higher equilibrium price.

How to calculate the marginal cost

In the question, we are told that the fixed and variable costs for 5 units of the sailboats are $4,000 each which equals $8000 in the summation.

Now for the sixth boat, the marginal cost can be obtained by subtracting the total cost for the 5 units with the new cost of $10,000. When we subtract the new cost from the old cost, we will get $2,000 and this is the marginal cost for the sixth boat.
