Answer:
D: tidal effects of the Moon
Explanation:
Answer:
Interphase 0.90 = 18 Hours
Prophase 0.04 = 48 Minutes
Pro-metaphase 0.02 = 24 Minutes
Metaphase 0.01 = 12 Minutes
Anaphase 0.02 = 24 Minutes
Telophase 0.01 = 12 Minutes
Answer: adenylyl cyclase inositol triphosphate mainly known as IP3 causes the release of Calcium ions directly from the inracellular stores and causea contraction.
Explanation:
IP3, inositol phosphate is a second messenger a signaling molecule. It is made by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, by an enzyme phospholipase C.
IP3 binds to the calcium channels and opens Ca2+ channels that are embedded in the ER membrane, releasing Ca2+ into the cytosol. Calcium ions released may cause contraction and regulate the Ca2+ channels in the membranes.
