Answer:
Exocytosis of vesicles containing glutamate from the nerve terminal would decrease
Explanation:
Glutamate release is regulated by voltage dependent calcium channels. An increase in intracellular Calcium ion concentration is sufficient and necessary to cause glutamate release from astrocytes. Several experiments are done on this study, when these cells are provided with high amount of calcium ions, the glutamate release from nerve terminals increased.
A) be unable to maintain homeostasis
The purpose of the cell cycle is to stope or to prevent cell division when it is not needed and make it happen when it is needed
Answer:
Option (2).
Explanation:
Cell division is the process by which cell increases its number with the help proteins and enzymes. The four main phases of the cell cycle are G1 , S, G2 and M phase.
The cell cycle sequence is important for the proper division of the cell. Any change in these sequences might result in cancer and other disease. The skipping or change of any stage might cause the lack of material. The cell will lose the energy to divide or may result in uncontrolled cell division.
Thus, the correct answer is option (2).
