What are some problems with eating fish from higher trophic levels?

Answers

Answer 1
Trophic levels refer to where organisms fall on the food chain. Fish from higher trophic levels are often larger and have a higher dollar value at market, resulting in overfishing and the depletion of those species from the wild. If those fish are continued to be consumed at a high level, the loss of predators at the top of the food chain could throw off the balance in the ecosystem.

One of the Germanic tribes was the Vandals.


TrueFalse

Answers

True. They were a Germanic tribe that lived in the East in the 5th century AD. Most probably, they lived on the territory of today's Poland. Thanks to many fights for supremacy, the Vandals ended up on the Iberian peninsula and even across the Mediterranean sea, in North Africa. They entered the popular culture as a synonym of barbarous tribes who destroyed everything in their sight. In truth, they weren't better or worse than their contemporaries in this respect.

What determines the size of a mineral crystal formed from magma?

Answers

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Final answer:

The size of a mineral crystal formed from magma is determined by the rate of the magma's cooling and the concentration of specific elements or compounds in the magma.

Explanation:

The size of a mineral crystal formed from magma is determined primarily by two factors: the rate at which the magma cools, and the amount of specific elements present in the magma. A slower cooling rate generally allows larger crystals to form, as the conditions conducive to crystal growth last for a longer period of time. On the other hand, a rapid cooling rate limits the growth of crystals, causing them to be smaller. Moreover, the presence of specific elements or compounds can also influence the size of the crystals. For instance, a magma with a high concentration of silica is more likely to form larger quartz crystals.

2. Which one advancement of the Second Agricultural Revolution do you think was the most significant and why?

Answers

Technological advancement. The second agricultural revolution was strongly influenced by the development of machinery and led to the industrial revolution. 

The most significant advancement of the Second Agricultural Revolution was the crop rotation system, which increased land productivity and, in conjunction with the seed drill, led to enhanced agricultural efficiency and set the stage for the Industrial Revolution.

Crop rotation helped to maintain soil fertility by rotating different crops on a piece of land over a period of time. This practice significantly increased the productivity of the land and, together with Jethro Tull's seed drill, revolutionized agricultural efficiency. Tull's invention enabled precise planting of seeds in rows, making weed control easier and enhancing crop yields. These innovations, among others from the era, greatly reduced the amount of labor required to produce food, leading to larger surplus production and setting the stage for the subsequent Industrial Revolution.

What is the significance of the Hudson river?

The Hudson River flows through New York for 315 miles (507 kilometers). The river was discovered in 1609 by an Englishman working for the Dutch East India Company named Henry Hudson, after whom Canada's Hudson Bay is also titled.

Native Americans lived in the Hudson River region long before European settlers did. The Lenape (also known as the Delaware Indians), the Wappingers, and the Mahicans were the three subgroups of the Algonquins, who resided along the river.

All throughout the colonization of the United States, the Hudson was frequently used for travel. The Hudson was a significant trade and transport route, although is smaller than several other American rivers. The Hudson River valley, which is adjacent to settlements in New York, was used during the Revolutionary War in the 1750s.

Hence, Options  (A), (C ), (F), and (H) are the right choices.

All of the following are names for canyons except

Select one:
a. ravines
b. gorges
c. chasms
d. lowlands

Answers

Ravines and gorges are names for canyons. Therefore, A and B are eliminated. Chasm is also another name for a canyon, so C is out. Lowland is described for a land that’s lying low, based off of sea level. The answer is D: lowlands.

Final answer:

The term that does not refer to a canyon is 'lowlands'. While ravines, gorges, and chasms are all types of canyons or canyon-like structures, lowlands are flat or gently rolling terrain without steep sides or significant depth. So the correct option is d.

Explanation:

All of the following are names for canyons except lowlands. Here's why:

Ravines: These are small to medium-sized canyons typically carved by running water and are narrow and steep-sided.Gorges: Similar to ravines, gorges are typically deeper and more narrow canyons, often with a river flowing through them.Chasms: These are very deep, narrow openings in the earth's surface, and they can be similar to canyons but are often more dramatic in depth compared to their width.Lowlands: This term refers to areas of land that are low in elevation compared to surrounding areas, which does not describe a canyon. Lowlands are the opposite of highlands and do not have steep sides or a significant depth that characterizes canyons.

Canyons are known for having been formed by the process of erosion over millions of years. The Valles Marineris on Mars, though often referred to as a series of canyons, was primarily formed due to tectonic cracks rather than erosion by water. However, water played a later role in shaping these canyons. Other processes like wind erosion also continue to shape existing canyons on Earth. These terms describe various types of steep-sided valleys, which are often associated with rivers or ancient water flow, unlike lowlands that represent flat or gently rolling terrain.

Is lake ontario the closest to great lake to ottawa and canada?

Answers

Yes it is the closest

No, Lake Ontario is not the closest Great Lake to Ottawa, Canada. The closest Great Lake to Ottawa is Lake Ontario's neighbor to the west, which is Lake Huron.

Lake Huron is the closest Great Lake to Ottawa, Canada, although it is not directly adjacent to the city. Lake Huron is located to the northwest of Ottawa, with a distance of approximately 300 kilometers (186 miles) from the city.

In contrast, Lake Ontario, which is the easternmost Great Lake and directly south of Ottawa, is farther away, with a distance of over 400 kilometers (about 250 miles).

While both lakes are part of the Great Lakes system and provide significant water resources and recreational opportunities for the region, Lake Huron is geographically closer to Ottawa than Lake Ontario.

why do astronomers find it difficult to locate extra-solar planets with telescopes

Answers

Ground-based telescope can not detect planet in the brightness of stars

Answer:

     About 300 planets have been located around stars other than the Sun, but this is usually by indirect measurements, such as the change in their passage over their stars' gravitational field, distorting the surrounding light.

  All the extrasolar planets detected so far were a hesitation on a chart, because most of them don't reflect any luminosity.

which group of american people would benefit the most if illegal immigration did not exist in the U. S.?
a. elders
b. high school drop-outs
c. big business entrepreneurs
d. people working in the medical field

Answers

Hello!

B - high school drop-outs would likely benefit the most if illegal immigration did not exist in the U.S.

Due to the fact that illegal immigrants are not legally in the country, they cannot obtain a driver's license/ID or any other legal documents. Most jobs require an ID when hiring. Because of this, illegal immigrants are forced to find low-paying jobs that to not ask for identification when hiring employees. Unfortunately, this puts legal American high school drop-outs at a disadvantage. Drop-outs do not have the chance to earn a diploma or any high-level credentials. This means that they would also need the low-paying jobs that the illegal immigrants are often working in. If illegal immigration did not exist in the U.S., high school drop-outs would benefit because they would be given the jobs that the illegal immigrants currently have.
