3.co-release and cotransmission of more than one neurotransmitter

Explanation:

The complete question is as follows:

The discovery of what properties of neurotransmission caused neuroscientists to rethink Dale's Principle?

  1. inhibition of neural activity
  2. neural communication at more than one place at a neuron
  3. co-release and cotransmission of more than one neurotransmitter
  4. finding similar neuronal activity in more than one location in the brain

  • Dale's principle was given by a scientist named Henry Dale in 1940's and the principle state that each neuron is capable of releasing only a single type of neurotransmitter.
  • This principle meant that a particular neuron is capable of performing only a single function at all the synapses.
  • However, Dale's principle were soon proven to be false when it was discovered that there are many neurons capable of releasing more than one neurotransmitter at a time and this is termed as cotransmission and co-release of the neurotransmitters.
  • An example of co-transmission is the release of GABA along with substance P as cotransmitter.

What type of ecological interaction is this? toad fish live on the bottom of the ocean. They bury themselves in the sand/mud and wait to ambush their prey, crustaceans and mollusks

Answers

Answer:

Predation

Explanation:

There are 4 main types of ecological interactions (these are 2 way interactions), and they are mutualism, commensalism, competition, and predation. This is predation because the toad fish are the predators, while the crustaceans and mollusks are prey. A basic definition for predation is attacking or plundering another, which is what the toadfish is doing to its prey.
