Answer: ionotropic; metabotropic
Explanation:
A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.
Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.
The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
The Answer is A but im only about 5% sure about my answer
Answer:
Apart from poisoning the fish, this toxic fishing activity kills animals that are essential to the aquatic environment, such as corals, and provide food and shelter for a number of marine species. One square meter of coral reef is lost with every fish captured using this method. Also, overfishing has the potential to deplete main reef habitats and damage coral habitat. In many places, rapid human population growth, increased demand, the use of more advanced fishery technology, and insufficient maintenance and regulation have resulted in the extinction of key coral species and habitat damage.
BTW, I used my own words
