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.
The answer is d because of heat and pressure
Earth’s orbital speed around the Sun is closest to OC) 850 mi/h
Whales play an important role in stabilizing the aquatic food chain and reproduction of other species.
As more whales are killed the food distribution in the ocean becomes destabilized and causes changes in the food supply of many other kinds of marine life.
Whales are vital to the food chain, stabilising food flow and maintaining a healthy ocean.
As such, the rapidly decreasing whale population will have major effects on the ocean's ecosystem.
Believe it or not, whale poop also serves quite an important purpose to the ecosystem.
Answer:
It's an alarming situation about the decline of commercial fish population and we must need to develop the policy solution to this dangerous fisheries problem.
We can develop more fish by fish hatcheries to increase the population of fish and release large number of fish into the ocean.
We should give the awareness to the general public related to decrease the recreational fishing impact.
Commercial fishing must be ban until we reaches the sustainable level of fish.
There must be place international limits to every country related to limited number of fish they can take.
