Plants can use sunlight energy in producing their own food and are examples of autotrophs. Do all autotrophs use sunlight energy to produce their own food? Explain why or why not.

Answers

Some autotrophs use sunlight energy to produce their own food. This is because autotrophs use a process called photosynthesis to make their food. This process uses energy from the sun, as well as water from the soil and carbon dioxide from the air to create glucose.

However, other autotrophs perform chemosynthesis, which does NOT require energy from the sun to produce food.

Overall, not all autotrophs use sunlight energy to produce their own food, but a large chunk of them do.

A few autotrophs use daylight energy to create their own food. This is on the grounds that autotrophs utilize an interaction called photosynthesis to make their food. This interaction utilizes energy from the sun, as well as water from the dirt and carbon dioxide from the air to make glucose.

What is an Autotroph?

An autotroph or essential maker is an organic entity that produces complex natural mixtures (like sugars, fats, and proteins) utilizing carbon from straightforward substances like carbon dioxide.

The essential makers can change over the energy in the light (phototroph and photoautotroph) or the energy in inorganic substance compounds (chemotrophs or chemolithotrophs) to construct natural atoms, which is normally amassed as biomass and will be utilized as carbon and energy source by different organic entities.

A few organic entities depend on natural mixtures as a wellspring of carbon, however can involve light or inorganic mixtures as a wellspring of energy. Such life forms are mixotrophs. A life form that gets carbon from natural mixtures yet acquires energy from light is known as a photoheterotroph, while a living being that acquires carbon from natural mixtures and energy from the oxidation of inorganic mixtures.

Therefore There are various sorts of essential makers out in the World's environment at various states.

Dark areas of the map represent places that are very windy. Wind energy is arguably the cleanest source of power. If you were committed to lowering your negative impact on the environment, where could you move to maximize your ability to harvest wind power?

Answers

Answer:

midwestern plains

Explanation:

No map was attached to this picture. Regardless the best place to move to maximize your ability to harvest wind power would be the midwestern plains. These plains are characterized as large open fields that have no trees, buildings, or hills and are usually just flatland with grass. This lack of variable resources gets rid of friction and allows wind to pick up speed in these areas to create a very windy environment. This is the ideal location for wind power.

building of canals reduced travel time. why

Answers

Answer:

because its help to make the shortest distance......

Answer:

It’s not the travel time, it’s the increase in efficiency, smoothness and reliability. But travel time was also speeded up, in particular because of the directness, allowing goods to go almost from door to door, instead of from town to town.

In Britain, when canals were first built, before roads or railways there were only the rough rural roads. Often impassable to wagons or coaches because of mud in winter, they were frequently reduced to being used only by packhorses.

But where a packhorse could only carry a couple of hundred pounds, and a wagon maybe a ton, a horse towing a canal boat could easily pull thirty tons or more. Slowly, but steadily.

I’m talking here of Britain, and in particular England, because it’s in England that mass canal-building took off.

There had been efficient navigations in the past (the most spectacular being the Canal du Midi in France in the 1680s, and China’s Grand Canal.) And they were larger in scale and far more efficient in carrying capacity than Britain’s modest canals.

But the explosion of Britain’s canal building, starting about 1760, happened precisely because they were small in scale, easier to drive through the countryside, and not dependent on the water large rivers of the big continents.

Indeed, the small scale meant they could be local - to the extent of running through towns and even in many cases right into factories.

They could thus act as ‘conveyor belts’ between factories. It’s this convenience that meant a small boat could deliver cargo (raw materials or coal or components from one factory to another, hugely speeding up delivery.

An example is in Birmingham, England, which went from sleepy farming town to one of the world’s great manufacturing cities in a couple of generations because of the 160 miles of small-scale canal navigations.

That was the significance of travelling time. Not the speed of travel, but the ability to ship around the country without having to tranship on the outskirts of a town.

Answers

The correcat answer is B). Equal Footing section of the Constitution gives equal status and power to all states.

What is an Equal Footing?

The Equal Footing doctrine is based on Article IV, Section 2, Clause 1 of the U.S. Constitution, which grants equal status and power to all states. This doctrine ensures that all states admitted to the Union are granted the same rights, privileges, and powers as the original states. It reflects the principle of equality among states in the United States and underscores the idea of states' sovereignty and autonomy within the federal system.

The Bill of Rights (A), Full Faith and Credit (C), and Privileges and Immunities (D) are other important constitutional concepts, but they do not specifically relate to the equal status and power of states as addressed by the Equal Footing doctrine.

Based on the passage, identify an issue faced by the Ottoman Empire in the 1600s.

Answers

This question is incomplete. Here's the complete question.

The power of the [Ottoman] Empire was waning [fading] by 1683 when the second and last attempt was made to conquer Vienna. It failed. Without the conquest of Europe and the acquisition of significant new wealth, the Empire lost momentum and went into a slow decline.  

Several other factors contributed to the [Ottoman] Empire’s decline:  

• Competition from trade from the Americas  

• Competition from cheap products from India and the Far East  

• Development of other trade routes  

• Rising unemployment within the Empire  

• Ottoman Empire became less centralized, and central control weakened  

• Sultans being less severe in maintaining rigorous standards of integrity in the administration of the Empire  

• Sultans becoming less sensitive to public opinion

Based on the passage, identify an issue faced by the Ottoman Empire in the 1600s.

Answer: The Ottoman Empire grew too extensively to be able to govern it.

Explanation:

Despite not being able to conquer Europe, the Ottoman Empire did grow by several conquests, and because of that it eventually shifted into a less centralized government, making the control of it more difficult.

Furthermore, the sultans´ weakening the standards of the administration of the Empire made the central government even more vulnerable.
