1. Divergent Plate Boundaries or Constructive Plate Boundaries. This is where two plates separate. Ridges are created when mantle convection rises up beneath it, with extreme heat, the crust will thin, and the igneous material beneath will eventually.
<span>2. Divergent, or destructive plate margins cause volcanoes. As the more dense plate subducts, it will melt at depth and the water driven off, will lower the melting point of the overlying mantle wedge, this will create a type of magma. Volcanic Island Arcs are formed at oceanic-oceanic destructive plate margins. The hot, bouyant magma, is less dense that the surrounding rock, so will rise to the surface, and will collect beneath the plate that hasn't been subducted. It will then, under increased pressure erupt under the sea. Over thousands to millions of years, it will keep erupting, to form islands. </span>
<span>3. Earthquakes are mainly caused at Transform boundaries and Divergent boundaries. At transform boundaries, two plates sliding past eachother, and the build up of friction could lead to earthquakes, if enough stress is built up and then suddenly released, then the energy is released as seismic waves or an earthquake. At divergent boundaries, earthquakes happen along the Benioff zone which is the slope of the subducting plate that is slowly being dragged into the mantle by mantle convection and slab pull. </span>
<span>4. Divergent boundaries cause orogenisis (mountain building). But only the continental-continental margin where two continental plates are colliding. Because they are the same density, they don't subduct, but they buckle, compress and uplift to form mountains. Just like the himilayas, when the Indian plate collided with the eurasian plate.</span>
Answer: option B) False
Explanation:
The body relies on SEVERAL sources for its energy or glucose supply.
Firstly, understand that Glucose could be supplied from the following:
Glycogenolysis (Glycogen break down induced by Glucagon)
Amino acids metabolism (once amine group is removed)
Fatty acid oxidation.
All of the pathways mentioned can directly or indirectly yeild GLUCOSE, thus making it UNNECESSARY for Carbohydrate meals to be consumed every 3 to 4 hours.
Therefore, the answer is False
Answer:
The number of thermal power plants increased between 1950 and 1975.
Explanation:
Here, the table that shows the amount of water withdrawn in billion gallons per year, between 1950 and 2005,
Year 1950 1965 1975 1990 2005
Amount 180 340 420 410 410
Since, 420 > 180,
Also, 50 percent of water withdrawn is used up by thermometric power plants.
Thus, thermal power plants in 1975 > thermal power plant in 1950
Therefore, the number of thermal power plants increased between 1950 and 1975.
Second option is correct.
Note : first option is incorrect.
Since, by the above table,
The least amount of water used by power plant is 180 billion gallons per year,
Thus, third option is incorrect,
Now, the table does not represents energy produced,
Fourth option can not be said correct.
Answer: <em>D. Causes an accumulation of lipids in brain cells</em>
Explanation:
Tay-Sachs disease is caused by a genetic mutation in the <em>HEXA</em> gene. It is an autosomal recessive disease that causes the mutation on an enzyme, which metabolizes <em>GM2 Ganglioside</em> in nerve cells, this leads to a build-up of the molecule in brain cells. At the moment there is no cure for the disease, only support treatment is available.
Insulin is released into the blood when oxygen levels are low and blood glucose levels are high
