Answer:
The higher the pressure on anything, the hotter it will get. The hotter a rock gets, the more possibility that it will have to melt.
So you're out the base of the crust, with any kilometers of crust above you, and that's a lot of pressure. Then take into account that you have thousands of degrees of heat coming from the mantle-core boundary, and directly from radioactive decay within the mantle, which only adds to the temperature.
The net result is like melting a stick of butter. It's very easy to do without a lot of energy -- since Earth is a massive ball of thermal energy, then well... it's easy to do.
How do the circulatory and respiratory systems deliver important
substances?
Answer:
Gas exchange between tissues and the blood is an essential function of the circulatory system. In humans, other mammals, and birds, blood absorbs oxygen and releases carbon dioxide in the lungs. Thus the circulatory and respiratory system, whose function is to obtain oxygen and discharge carbon dioxide, work in tandem.

In your own words, explain how stalagmites are formed in caves.
Explanation:
As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite. Speleothems form at varying rates as calcite crystals build up.A male cardinal’s red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
increased variation in the shades of red because there is no advantage in one specific color
increased variation in the shades of red because the cardinals try different ways to impress the females
decreased variation in the shades of red over time because no form of the trait is advantageous
decreased variation in the shades of red after a single generation
Answer:
decreased variation in the shades of red over time because no form of the trait is advantageous
Explanation:
If the vibrant red feathers are no longer used to attract mates, then it is no longer useful to the males, so it will cease to exist.
Answer:
C. decreased variation in the shades of red over time because no form of the trait is advantageous

Human blood consists of blood groups A, B, and O. However, there is one more blood group, AB, which contains alleles A and B in the same genotype. What is this phenomenon called?
A.
coinheritance
B.
codominance
C.
incomplete dominance
D.
polygenic inheritance
Answer:
B. codominance
Explanation:
because if the placement of the A and B molecules on each cell is controlled by the proteins that are coded by different versions of the same gene, then IA and IB are codominant but both are dominant to Io. If a person receives an IA allele and a IB allele, their blood type is type AB, in which characteristics of both A and B antigens are expressed.

A plant cell has a 5%, percent salt concentration. It is placed into a solution
containing a 12%, percent salt concentration.
Explain what will happen to the cell and why?
Answer:
Water in cells moves toward the highest concentration of salt. ... If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt.
Explanation:
- Lee el siguiente párrafo y a continuación responde lo que se te pide.Los seres humanos primitivos comenzaron a clasificar las plantas y los animales tanto por su utilidad como por el daño que les causaban, luego fueron profundizando aún más en sus conocimientos sobre la flora y la fauna de su entorno, identificando los ciclos biológicos y hábitat, entre otros aspectos que facilitaron su producción y pronta disponibilidad. Con base en el párrafo anterior se puede afirmar que: * 1 punto A) Empezaron a entablar una relación más estrecha con el medio ambiente. B) Abandonaron su vida primitiva y nómada C) Incrementaron sus conocimientos únicamente sobre el ciclo del agua. D) Empezaron la agricultura y la piscicultura.
Answer:
A) Empezaron a entablar una relación más estrecha con el medio ambiente.
Explanation:
Desde el pasaje, podemos ver que la gente comenzó a prestar más atención a su entorno y cómo la fauna y la flora afectan la vida humana.

How is the changing environmental quality posing a challenge to agricultural industries?
Soil polluted with heavy metals causes crops to grow more quickly.
Higher birth rates in livestock are due to land pollution.
Water and land pollution make it more difficult to grow healthy crops and livestock.
Droughts cause more people to move to rural areas.
Answer:
Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive, or poorly timed application of pesticides, irrigation water, and fertilizer. Industrial farming practices, such as monocropping and intensive tillage, have also compromised soil health over time. ... Excessive fertilizer use can also cause a buildup of salts in soil, heavy metal contamination and accumulation of nitrate (which is a source of water pollution and also harmful to humans
Explanation:
However agriculture is both cause and victim of water pollution. It is a cause through its discharge of pollutants and sediment to surface and/or groundwater, through net loss of soil by poor agricultural practices, and through salinization and waterlogging of irrigated land.

Numerous atp and naphtha are produced during light reaction why
Answer: cracking of naphtha. It is important to ensure that the feedstock does not crack to form carbon, which is normally formed at this temperature. This is avoided by passing the gaseous feedstock very quickly and at very low pressure through the pipes which run through the furnace Shale naphtha is obtained by the distillation of oil produced from bituminous shale by destructive distillation. Petroleum naphtha is a name used primarily in the United States for petroleum distillate containing principally aliphatic hydrocarbons and boiling higher than gasoline and lower than kerosene.
Explanation: Light naphtha can refer to either a finished product used as a petrochemical feedstock or a distillation cut commonly called light straight run naphtha. It is composed of pentane and slightly heavier material. In a refinery, light naphtha is often blended directly into gasoline.
