Answers

Answer 1

Answer:

Explanation:

Measuring the amount of deu terium in the universe allows us to set a limit on the density of ordinary matter of universe. Density of the universe is about 9×10-27 kg m-3, because of the way in which deu terium was created in the Big B ang, an exact measurement of the amount of deuterium would allow scientists to set limits on the models of the great explosion.

PLEASE HELPPPP!!!!!!!!!!!!Which statement is TRUE about northern geography and its impacts?

A.The climate mekes farming difficult in New England

B.Very few trees grow in the Great Plains due to the cold

C.The most northerly States have the longest growing season

D.States in the north experience only two different seasons​

Answers

Answer:

c

Explanation:

The correct statement about northern geography and its impacts is A: The climate makes farming difficult in New England. This is a true reflection of the challenges faced by the region due to its climate.

The North is one of the least densely populated regions in North America, characterized by brutally cold winters, short growing seasons, and poor soil quality. These factors make farming particularly challenging in places like New England. The statement that the most northerly states have the longest growing seasons is incorrect due to the extreme cold and long winters, which significantly shorten the growing period for crops. Additionally, the Great Plains, contrary to the assertion that very few trees grow there due to the cold, actually have a different natural vegetation profile, with tree growth not being primarily limited by temperature. As for the North experiencing only two seasons, this is also incorrect as the northern states experience four distinct seasons, although winter may be significantly longer and harsher than in other regions.

How do toponyms become a part of the cultural landscape? Give an example?

Answers

Answer:

A toponym is the name of a place. Boston, Australia, and Montreal are all toponyms. ... Words ending in nym are types of names, like an eponym is a name for a thing that came from a person's name. A toponym, therefore, is a name for a place.

Explanation:

Toponyms serve as symbols of regional culture and thus reflect the history, habitat and environment of a place. Toponymic studies examine the origin and development of an ethnic group, present the spatial patterns of a certain culture and reveal both man- made and physical environmental features of a region.

Radiometric dates calculated from minerals in sedimentary rocks produce ages that ________.
a. are just as accurate as when the technique is applied to igneous rocks
b. are too young (postdate sedimentary deposition)
c. are too old (predate sedimentary deposition)
d. represent the time the sediments became lithified

Answers

Answer:

c. are too old (predate sedimentary deposition)

Explanation:

Radiometric dates calculated from minerals in sedimentary rocks produce ages that are too old and often predates the sedimentary deposition.

Radiometric dating involves the uses of radioactive elements in rocks to measure the absolute age of rock.

It involves comparing the daughter to parent ratio because the decay started when the minerals formed in a rock in a period of crystallization or metamorphic event.

Sedimentary rocks are often made up of re-worked minerals. They are derived from pre-existing igneous and metamorphic rocks. When radioactive minerals from these sources finds their way into sediments, they give the age of their parent rock and not that of the sedimentary rock because their activity is not being reset.

The radiometric dates from minerals in sedimentary rocks are usually too old because they reflect the age of the minerals' original crystallization, not the formation of the sedimentary rock. Therefore, the correct answer is option c. For accurate dating, other methods like relative dating using cross-cutting igneous rocks are used.

The question states- "Radiometric dates calculated from minerals in sedimentary rocks produce ages that ________. The correct answer is c. are too old (predate sedimentary deposition).

This happens because radiometric dating measures the age of the minerals at the time they crystallized, which often occurs long before they were part of the sedimentary rock.

This makes the minerals in sedimentary rocks older than the rock itself. For dating sedimentary rocks, methods like relative dating of cross-cutting igneous formations or using fossils are more accurate.

Radiometric dating tells you different things depending on which geologic material you're studying. For minerals in igneous rocks, the radiometric age tells you when the mineral crystallized from magma.

In metamorphic rocks, some isotopes can tell you the age of metamorphism, but for sedimentary rocks, the radiometric age pertains to the original crystallization in their parent rock, not the sedimentary rock formation.

Therefore, as per the above explaination, the correct answer is option c that is "are too old (predate sedimentary deposition)".

why is the Mississippi river more of a highway than the amazon river?

Answers

Final answer:

The Mississippi River is a more significant transportation route compared to the Amazon River due to its longer history of human settlement and development, its strategic location connecting major cities and agricultural regions, and its extensive use for navigation purposes with the introduction of steamboats.

Explanation:

The Mississippi River is more of a highway than the Amazon River due to several factors. First, the Mississippi River has a longer history of human settlement and development, which has led to the construction of infrastructure such as ports, docks, and transportation networks. Second, the Mississippi River flows through the heartland of the United States, connecting major cities and agricultural regions, making it a vital transportation route for goods and commerce. Lastly, the Mississippi River has been extensively used for navigation purposes, with the introduction of steamboats during the transportation revolution, which further solidified its status as a major water highway.

What is the function of the large, sheetlike pectoralis muscles of a bird it moves the tail to form a rutter system it anchors the feet when the bird perches it provides the wing upstroke it provides the wing's downstroke?

Answers

Answer:

it provides the wing's downstroke

Explanation:

the function of the large, sheetlike pectoralis muscles of a bird is that it provides the downstroke of the wings.

The pectoralis muscles of a bird enable the wing's downstroke during flight, while the supracoracoideus muscles allow the upstroke, with both attaching to the sternum's keel. The sternum's enlarged size and the flexible furcula (wishbone) support the demand for muscular strength and flexibility required for flight.

The large, sheetlike pectoralis muscles of a bird are primarily responsible for the wing's downstroke during flight. These muscles are highly developed and account for a significant percentage of a bird’s body mass relative to most mammals. The contraction of the pectoralis major muscles attaches to the keel of the sternum and pulls the wings downward. In contrast, the supracoracoideus muscles are involved in the wing upstroke, moving the wings upward through a tendon mechanism that passes over the shoulder bones. Both sets of muscles play critical roles in flight, with the pectoralis assisting in generating lift and thrust.

Birds' skeletal structures, including a large sternum and a fused clavicle forming the furcula or wishbone, further support the muscle work during flapping. The large sternum accommodates the substantial flight muscles, while the elastic furcula provides resilience and strength to the shoulder girdle as the wings beat.

Why was slavery in the United States a paradox?

Answers

Answer:

Freedom and slavery, the 'central paradox of American history' In October 1705, Virginia passed a law stating that if a master happened to kill a slave who was undergoing “correction,” it was not a crime. Indeed, the act would be viewed as if it had never occurred.

Explanation:

Slavery in the United States was a paradox because the Constitution states that all men are created equal, yet the same document allowed for people of color to be enslaved.

Before the Industrial Revolution, a light-colored variety of peppered moth was well camouflaged among light-colored lichens that grew on the bark of trees around London. A dark-colored variety of the peppered moth probably existed but was rarely observed because it was so easily seen by birds and eaten. When industry was introduced in London, soot killed the pollution-sensitive lichens, exposing dark tree bark. As a result, the dark- colored variety of the moth became the better carnoutlaged of the two moth varieties.
57.

In this situation, what is the relationship between the birds and the moths?
(1) producer-consumer
(2) predator-prey
(3) parasite-host
(4) autotroph-heterotroph

Answers

Answer:

2. Predator - Prey

Explanation:

Preys are animals or fauna that are haunted and killed by another animal for the sake of food. Preys are simply animals haunted for food.

Predators are the animals that naturally preys or hunt other animals for food. They kill and eat other animals.

In this scenario, the bird is the predator that hunts and kill the preys which are the moths for food. Therefore, the relationship that exist between the birds and moth is a predator-prey relationship.

Answer:

The correct answer is:

Predator-prey (2)

Explanation:

A predator-prey relationship is a relationship between two species when one species is being fed on (prey) and another species is being fed (predator). In this example, the dark-colored moths were easily seen and eaten by birds, hence the birds are the predators, while the moths are the preys.

The other types of relationships listed are

Producer-consumer; here a species of organism are responsible for the conversion of simple chemical substances into more complex substances called food these organisms are called producers. Examples are the green photosynthetic plants that produced food substances from carbondioxide and other simple substances, while consumers are every other organisms that lack the ability to make these special conversions

parasite-host; a parasite-host relationship is one when an organism of usually a lesser complex species (parasite) benefits from another organism(host) thereby harming it in the process.

autotroph-heterotroph; similar to producer consumer relationships, autotrophs are organisms that can produce their own food from substabces found in their sorroundings eg light for photosynthetic organisms and chemicals for chemosynthetic organisms, while heterotrophs are organisms that depend on other organisms (plants or animals or both) for food.

When the Soviet Union controlled Central Asia _?_ .
A. people were forced to work on government farms
B. industrialization was discouraged
C. urban areas declined
D. most people became nomadic herders

Answers

B because is the correct answer

Final answer:

During the control of Central Asia by the Soviet Union, people were compelled to work on collective farms as part of the government's collectivization policy, which brought about significant demographic and cultural changes as well as economic hardships, including widespread famines.

Explanation:

When the Soviet Union controlled Central Asia, people were forced to work on government farms. This policy was part of a larger movement called collectivization, where the government sought to reorganize agriculture into large farm collectives instead of individual farms. This process entailed nomadic peoples settling in cities or on collective farms and donating their land, animals, farm equipment, and farm buildings to the collective farm.

During this period, Central Asians experienced a significant cultural shift as millions of Russians and Ukrainians were resettled into the region, introducing a mix of local and Russian culture, particularly in urban areas. Furthermore, the massive resettlement and collectivization policies led to widespread famine, particularly in the 1930s, due to crop seizures and mismanagement. This had long-lasting effects, including the loss of livestock which did not recover until the 1950s.

What is the difference between continent-continent divergence and ocean-ocean divergence?

Answers

Answer:

Continent-Ocean Convergence is similar to ocean-ocean convergence. One important difference is that in continent-ocean convergence mountains are formed instead of islands . When oceanic and continental plates collide or converge, the oceanic plate (denser plate) subducts or plunges below the continental plate (less dense plate) forming a trench along the boundary.

Explanation:

Continent-continent divergence results in rift valleys and possibly new ocean basins, while ocean-ocean divergence forms mid-ocean ridges and new oceanic crust. Both processes involve tectonic plates moving apart in different environments.

Differences Between Continent-Continent Divergence and Ocean-Ocean Divergence

Understanding the differences between continent-continent divergence (CCD) and ocean-ocean divergence (OOD) is crucial in the study of plate tectonics.

Continent-Continent Divergence (CCD)

In CCD, two continental tectonic plates move away from each other. This movement causes the formation of rift valleys, such as the East African Rift. Over time, if the divergence continues, it can lead to the creation of a new ocean basin.

Ocean-Ocean Divergence (OOD)

OOD occurs when two oceanic plates diverge at mid-ocean ridges, creating new oceanic crust as magma rises from below the Earth's surface. This process forms underwater mountain ranges, such as the Mid-Atlantic Ridge.

In summary, CCD involves the separation of continental plates leading to rift valleys and potentially new ocean basins, while OOD leads to the formation of mid-ocean ridges and new oceanic crust. Each type of divergence shapes the Earth's surface differently.

which of the following are examples of a negative feedback loops? A. global warming B. a thermostat that controls the heat in your home C. Loss of bioriversity D. fruit ripening E. convection currents F. I dont know yet​

Answers

Answer:

C and A

Explanation:

Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

The following are the examples of negative feedback loops:

A. global warming

C. Loss of biodiversity

A negative feedback loop is also called as an inhibitory loop. It is a kind of self-regulating system.It inhibits the future production of output by the system. For example, the body reduces manufacturing of some proteins or hormones when their level is too high. A thermostat that controls heat, ripening of fruit, and convectional currents are not the examples of a negative feedback loops. Global warming is the increase in the green house gases into the atmosphere. Carbon dioxide is one of green house gases. The level of carbon dioxide in the atmosphere can be controlled by the absorption of carbon dioxide gas from the atmosphere by the plants. This process is self regulating. But if plants are removed by deforestation then it will increase the global warming. Loss of biodiversity can inhibit the future production of output of the system that is the total number of species that will reduce in future.

Hence, A. global warming, and C. Loss of biodiversity are the correct options.

What is the distance across the river from okmar to the big rock

Answers

Answer:

The distance across the river from Omkar to the big rock is 131343149 meters

Step-by-step explanation:

* Lets study the information in the problem

- Let Omkar position is point A

- Let Melissa position is point B

- Let big rock position is C on the other side of the river

* Now we have triangle ABC

- The distance between Omkar and Melissa is 100100100 meters

 along the river

- The angle between Omkar and the big rock is angle BAC

∴ m∠BAC = 33°

- The angle between Melissa and the big rock is angle ABC

∴ m∠ABC = 98°

- The big rock is at angle C

* Now we can find the distance between Omkar and the big rock

 by finding the length of side AC in the triangle

- By using the sine rule

∵ sin A/BC = sin B/AC = sin C/AB

∵ AB = 100100100 meters

∵ m∠ABC = 98°

- Lets find m∠C

∵ In any triangle the sum of the measures of the interior angles is 180°

∴ m∠A + m∠B + m∠C = 180°

∵ m∠A = 33° , m∠B = 98°

∴ 33° + 98° + m∠C = 180° ⇒ add

∴ 131° + m∠C = 180° ⇒ subtract 131 from both sides

∴ m∠C = 49°

- Now lets use the sine rule

∵ sin ABC/AC = sin C/AB

∴ sin 98/AC = sin 49/100100100 ⇒ by using cross multiplication

∴ AC = (sin 98 × 100100100) ÷ sin 49 = 131343148.8

∴ AC ≅ 131343149 meters

* The distance across the river from Omkar to the big rock is
