Answer:

b. 3,2,4,5,1

Explanation:

3. The action potential induces an electrochemical process that causes release of the acetylcholine.

2. Release of acetycholine into synaptic cleft is down an electrochemical gradient, i.e through diffusion and not requiring energy input.

4. Acetylcholine then binds and activates ligand-gated ion channels of the muscle fiber to open up.

5. Sodium ions will flow into the muscle generation an action potential that will culminate into contractions.

1. The enzyme acetylcholinesterase will breakdown any acetycholine not needed in the synaptic cleft.

European rabbits were introduced into Australia and quickly spread, reproduced, and became a terrible pest. They eat up to $600
Alina [70]

Answer:

True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.

Explanation:

  • An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
  • Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
  • Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.

Compare and contrast the adaptations of free-living flatworms and parasitic flatworms
sammy [17]

<u>Answer:</u>

Free-living flatworms have developed a nervous system which helps them to sense the food. They have a head at one end of the body and each side of the head has sensory cells. These cells help them to sense chemicals and other movements around them.

 

While Parasitic flatworms don't have any nervous or digestive system as they live on the food digested by the host. They have special hooks attached to their head which help them to attach a host. They have developed some covering called 'teguments' which protect them from digestive liquids.
