wax represents rock. different colors means different types of rock. the squeezing n folding represent rocks being compressed n folded together. heating in pan is rock getting heated. the whole experiment demonstrates how metamorphic rock is formed.
335 million years ago. The continents together were called Pangea(the supercontinent)
Answer:
The given statement is True.
Explanation:
Scala media has endolymph as its constituent and endolymph is rich in Potassium ions (K+)
whereas
Scala tympani and scala vestibuli has in its composition Perilymph and Perilymph has sodium ions as their major constituent ions.
Therefore, scala media is Potassium ion rich while scala tympani and vestibuli are sodium ion rich.
The answers is all of the above
Answer:
d) A constitutively active mutant form of PKA in skeletal muscle cells would lead to an excess in the amount of glycogen available.
Explanation:
This occurs in the process of Glycogenolysis. The process involves breaking down of glycogen to glucose -1- phosphate and glycogen which helps in the release of glucose into the blood stream to prevent hypoglycemia(low blood sugar). The glucose-1-phosphate is later converted to glucose -6-phosphate. The latter enters the glycolytic pathway in which the reaction is catalysed by the enzyme phosphoglucomutase.
This homeostatic glucose regulation is regulated by the protein kinase(PKA)/ cAMP pathway in the skeletal muscles, the liver and the pancreas.
