describe energy flow in and from Earth's interior. HELP PLEASE
Answers
Answer:
There is a total of three processes within the Earth's interior:
convection, conduction, and radiation.
Explanation:
The question refers to the ways of heat, as energy, which is transferred or transmitted, from one body to another, because of difference in temperature between them. Conduction, Convection and Radiation, are the mechanism by which heat ( as energy) can be transferred or transmitted.
Conduction.
This mechanism the direct transfer of energy through a material due to the movement of molecules at high temperatures to the molecules at lower temperatures.
To be noted that the term “conduction” is also used in electricity as electrical conduction in materials (in general) and is the transference of an electrical charge from one position to another. Metals conduction is due to the high mobility of electrons which migrate though the crystal lattice.
Convection.
Refers to the heat transfer mechanism for substances which show small/poor heat transfer, by direct conduction, such as fluids ( liquids, vapours, and gasses). There are two processes involved in convention of heat ( or energy) transfer, the Natural Convection and the Forced Convection. In both processes there are various parameters involved for the calculation of heat transfer. These include the specific heat and thermal conductivity of the fluids, the density, the velocity etc.
Radiation.
This mechanism of heat transfer is based on the fact that all bodies emit energy by radiation, in the form of electromagnetic waves, but without the need of conducting medium. By definition the speed of light is the speed at which light waves propagate through materials is 299 792 458 m/s ( or 299792 km/s ) in vacuum. However, due to interaction of the magnetic and electrostatic fields, and produce various different effects depending of their wavelength.The heat is transmitted between the end of region of radio waves ( Radio waves are long wavelengths and very short waves called gamma (γ) Ray's)
At about halfway between these two wavelengths there is a small section which is “visible (by human) light,” and the “ very high frequency light” which is the end of the radio waves exists the the range of wavelengths by which heat is transmitted. Actually this range frequencies which is below the frequency of red light is the “ infrared “. The amount of heat radiated, as well as the range of wavelengths where the radiation takes place is determined by the temperature of the body under consideration.
But to answer your question:
Three mechanisms—convection, conduction, and radiation—transfer energy throughout the Earth's internal system, including the atmosphere, oceans, and surface. On either a small scale or a big size, all of these processes can take place simultaneously. The atmosphere and ocean are discovered to be strongly coupled.

During volume changes in the thoracic cavity, what is primarily responsible for changes in length?.
Answers
During volume changes in the thoracic cavity, Diaphragm is primarily responsible for changes in length.
The main components of the respiratory system are the two lungs. They are located in the thoracic cavity, which is the area to the left and right of the heart. The rib cage safeguards the cavity. Other components of the respiratory system are supported by a muscular sheet known as the diaphragm.
The diaphragm contracts and pulls downward upon inspiration, or when the lungs inhale. The muscles between the ribcage tighten and pull upward at the same time. As a result, the pressure inside the thoracic cavity lowers and its size grows. Air rushes in as a result, filling the lungs.
Thus, diaphragm is responsible for the increase in length of the thoracic cavity.

Below is a list of their concerns as well as how important each issue is to the community. Community Concerns Concern Level Wave action Low Beachfront development Low Nearshore aquaculture Low Health of nearby coral reef Moderate Roosting bird species High Storm surge threat High Which of the following solutions would best address the issues of greatest concern in the community? Construction of a seawall Construction of a seawall A Planting mangrove forests Planting mangrove forests B Construction of an offshore breakwater Construction of an offshore breakwater C Adding large sand dunes
Answers
Answer: B, planting mangrove forests
Explanation:
Healthy mangrove forests provide homes for roosting bird species, protect coastal communities from storm surges, and provide a nursery habitat for juvenile coral reef organisms.
A is incorrect because the construction of a seawall would prevent the threat of storm surge but would not provide a habitat for roosting bird species nor help the health of the coral reef.
C is incorrect because the construction of an offshore breakwater would prevent the threat of storm surge but would not provide a habitat for roosting bird species. Its construction would also likely damage the nearby coral reef.
D is incorrect because creating large sand dunes could initially protect from storm surges, but this can also cause erosion. Sand dunes would not provide habitat for roosting bird species nor would they help to protect the health of the coral reef.
The introduction of certain animals from Europe, especially horses, had a positive effect on some American Indian communities. However, European cattle and other livestock sometimes caused more harm than good. In some cases, livestock entered the unfenced fields of American Indian farmers, eating and trampling their crops. Unlike European farmers, many American Indian farmers had never learned how to fence in their fields because it had never been necessary. The American Indians in the Spanish colony of New Spain in Central and North America experienced this problem. Antonio de Mendoza, the first viceroy of New Spain, wrote these words to the Spanish king in the 1530s: May your Lordship realize that if cattle are allowed, the Indians will be destroyed. How could the Spanish have helped American Indians adapt to the new species of livestock?
Answers
Answer:
Explanation:
To reduce the incidents of destruction of field by this animals the Spanish could have helped adapt by taming the animals, the animals can be kept in a ranch where they would be controlled to prevent them from entering fields.
The American India could be enlighten through orientation about how to keep their farms save from invasion by this pest animals.
The India should be enlighten about the animal and its mode of operation and how to prevent the entry of this animal pest into their field. This will help them adapt to animal.
With this the India would be able to feel loved and start adapting to the new changes.

Question Between about 1910 to 2010, average global temperatures across Earth's surfaces increased about 0.6 ° Celsius. During the same period, average ocean temperatures increased about 0.1 ° Celsius. What explains the difference between the changes to average global temperatures and average ocean temperatures?
Answers
Answer:
The difference between the changes to average global temperatures and average ocean temperatures can be explained by the fact that the ocean has a much greater capacity to absorb heat than the atmosphere. This means that the ocean can store much more heat than the atmosphere can, and as a result, it takes much longer for the ocean to warm up or cool down compared to the atmosphere. This process is known as thermal inertia.
Additionally, the ocean has currents that can transport heat from one region to another, which can also contribute to differences in temperature between different parts of the ocean. Furthermore, the surface of the ocean is constantly being mixed by wind and waves, which can help distribute heat throughout the water column.
Therefore, while both the atmosphere and the ocean are warming as a result of human-caused climate change, the ocean is absorbing much of the excess heat, resulting in a slower rate of warming for the ocean compared to the atmosphere.
Explanation:
This has to do with the special property of water regarding its specific heat capacity. This is why oceans heat up and cool down slower than land.
What is specific heat capacity?It is the quantity of heat required to raise the temperature of a substance by 1⁰C. Mathematically, it is the heat capacity of the substance over mass of the sample.For water, the specific heat capacity is approximately 4.2 J/g°C. This means, it takes 4.2 J of energy to increase the temperature of 1 gram of water by 1⁰C.As a result, the ocean takes far longer to warm up or cool down than the atmosphere. This is because the ocean can store much more heat than the atmosphere.The ocean also comprises currents that can move heat from one area to another, which can also be a factor in the temperature disparities across various oceanic regions.To find out more about specific heat capacity, visit:

Which of the following abnormal lab values indicates the presence of an acute myocardial infarction? elevated creatine kinase levels
Answers
Elevated creatine kinase (CK) levels can indicate the presence of an acute myocardial infarction (AMI).
CK is an enzyme found in various tissues, including the heart muscle (myocardium). During an AMI, the blood supply to the heart muscle is significantly reduced or completely blocked, leading to myocardial cell damage. As a result, the damaged myocardial cells release CK into the bloodstream.
Therefore, elevated CK levels in the blood can be an indication of myocardial injury, including AMI. However, it is important to note that CK levels can also be elevated in other conditions, such as skeletal muscle injury, so additional diagnostic tests are typically performed to confirm an AMI.

Only weak reproductive barriers existed by this time, so the two populations could freely interbreed and re-establish gene flow. This outcome in a hybrid zone is known as _____. See Concept 24.3 (Page) View Available Hint(s)for Part A speciation reinforcement fusion punctuated equilibrium stability
Answers
The outcome in a hybrid zone that resulted when some members of two populations of a certain species of salamander, which had diverged from each other after being split into two populations by a wide, dry valley, began to interbreed, despite the only weak reproductive barriers that existed by that time and re-establish gene flow is called "fusion."
The divergence of two or more populations into separate species is known as speciation. Speciation results from the evolution of reproductive isolation between populations that were once capable of interbreeding and exchanging genes. Because they stop the movement of genes between populations, reproductive barriers are important mechanisms that cause reproductive isolation.Reproductive barriers can be separated into two types based on when they occur: prezygotic and postzygotic barriers.
Prezygotic barriers are barriers that keep two populations from forming a zygote (a fertilized egg) and developing an embryo, whereas postzygotic barriers keep two populations from producing viable, fertile offspring once a zygote has been established and an embryo has begun to develop.One form of reproductive isolation is when two or more populations live in the same geographic area but do not interbreed, or interbreed only rarely. This is called sympatric speciation. Sympatric speciation is possible due to the fact that even if two populations are located in the same place, reproductive barriers can still emerge that prevent them from interbreeding and exchanging genes. Additionally, sympatric speciation can occur through a number of different mechanisms, including disruptive selection, where two different phenotypes are favored in different environments, and polyploidy, where an error in cell division leads to extra sets of chromosomes.

"what fraction of plants in the f2 will have the yellow seed, tall phenotype?"
Answers
The proportion of F2 plants that exhibit the tall, yellow-seed phenotype would be 4/16, which may be expressed as 1/4 or 25%.
Thus, Punnett square is used to identify the potential genotypes and phenotypes in the F2 generation if we believe that the yellow seed and tall phenotypes are controlled by single genes, with yellow (Y) being dominant over green (y) and tall (T) being dominant over short (t).
The genotypic ratio in the F2 generation of two heterozygous plants (YyTt x YyTt) would be 1 YYTT: 2 YYTt: 1 YyTT: 2 YyTt: 1 YYtt: 2 Yytt: 1 yyTT: 2 yyTt: 1 yytt.
We can observe that out of the 16 potential genotypes in the F2 generation, 1 + 2 + 1 = 4 display the yellow seed and tall phenotype that we are interested in (YYTT, YYTt, YyTT). The proportion of F2 plants that exhibit the tall, yellow-seed phenotype will be 1/4 or 25 percent.

what is shunting the blood so that it may be filtered known as?
Answers
Answer: Dialysis
Explanation: Dialysis involves either shunting the patient's blood through a special machine (haemodialysis) that helps remove the wastes while preserving water and salts, or removing wastes through fluid introduced into the abdomen (peritoneal dialysis).
Shunting the blood so that it may be filtered is known as Hemodialysis. It is a long answer. Hemodialysis is a process of removing waste and extra fluid from the blood.
Blood is filtered outside the body using a machine called a dialyzer, also known as an artificial kidney.The process of shunting blood for it to be filtered during hemodialysis is done through a vascular access, which is created by a minor surgery that connects an artery and vein, usually in the arm. The blood is pumped from the patient's bloodstream into the dialyzer, which filters the blood, and the filtered blood is returned to the patient's bloodstream.
Hemodialysis is used when the kidneys are unable to filter the blood on their own due to kidney failure. This may be caused by various factors, including diabetes, high blood pressure, glomerulonephritis, and other kidney diseases. Hemodialysis is usually done three times a week for three to five hours per session.
