Molten material is allowed to solidify into the final shape.
Casting defects occur during solidification:
Gas porosity
Shrinkage
Two stages of solidification:
Nucleation
Growth
Answer:Through polymerization reactions.
Explanation:
This happens when monomers bond together to form a polymer.
Answer:
Option-D
Explanation:
Parkinson's diseases are a neural disorder which affects the movement of the human body. The disease is caused by the low production or no production of dopamine by the neurons which thus interfere with the impulse transfer and thus movement.
In the given question, the patient with Parkinson's disease is provided with levodopa but no improvement is observed therefore the prescriber must change the drug regimen, for example, the levodopa should be given in combination with carbidopa. These medications enter the blood-brain barrier and get converted to the dopamine.
Thus, Option-D is the correct answer.
Mitosis should be the answer. if not that, then cell division. hope this helps :3
Answer:
Types of minerals change in heated<u><em> metamorphic </em></u>area rock. A record of biological time can be found in <u><em>sedimentary</em></u> area rock. Matter changes state from liquid to solid to form<u><em> igneous </em></u>area rock
Explanation:
Metamorphic rocks can be described as a type of rocks which arise by the phenomenon of metamorphism. Immense heat and pressure changes previous rocks (sedimentary, igneous or other metamorphic rocks) into metamorphic rocks.
Sedimentary rocks can be described as the type of rocks which are made by the deposition of minerals or organic particles and hence, help in evolutionary studies.
Igneous rocks can be described as the rocks which are made from lava or magma (hence changing state from liquid to solid).
