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.

how does the tourism industry in Thailand created a need for elephant sanctuaries.
Answer:
The elephants get exploited for the money that tourist bring in. Often times they are abused, not cared for, chained up, and beat into doing tricks and entertaining tourists. This creates the need for sanctuaries because the elephants need a safe haven from abusive owners who exploit then. Hope this helps

Which prop would be most appropriate on the set of Brighton Beach Memoirs to indicate that the play takes place in 1937? a black-and-white photograph of the New York Yankees a pitcher filled with lemonade and four empty glasses a color television a wood-burning stove
Answer:
The most appropriate choice on the set of Brighton Beach Memoirs to indicate that the play takes place in 1937 would be:
a black-and-white photograph of the New York Yankees
Explanation:
To understand this answer we need to evaluate the rest of them. First of all, none of them would be black and white in an era of black and white pictures. Second, the pitcher filled with lemonade would not indicate the time. Third, the wood-burning stove would be from an earlier time and the color television would be from a more recent time, also both would not match their own time. Therefore, the picture is the correct answer.
Answer:The most appropriate prop on the set of "Brighton Beach Memoirs" to indicate that the play takes place in 1937 would be a black-and-white photograph of the New York Yankees.

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

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
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.

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
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)".

Answer:
C). Corundum
Explanation:
Corundum is a crystalline type of aluminum oxide that usually contains iron, titanium, vanadium and chromium traces. Corundum is an incredibly durable and hard material. It is the third hardest mineral, after moissanite and diamond.
A geologist determine that a sample of a mineral can’t be scratched by a steel naill but can be scratched by a Masonary drill bit. Based on this information, the sample mineral has to be softer than CORUNDUM.
Due to Corundum's hardness , it can scratch almost every other mineral, and Since corundum is harder than the drill bit of masonry that can smash the mineral sample and thus the mineral sample must be softer than corundum.
Answer:C
Explanation:Corundum is an extremely hard crystallized alumina, used as an abrasive. For example Ruby and sapphire
Corundum is extremely hard and it can scratch most minerals and than the drill bit of masonry that can smash the mineral sample.Which means mineral sample must be softer than corundum for this to be possible .

What is the distance across the river from okmar to the big rock
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
131343149 meters
