Answer:
Neurotransmitters
Explanation:
Neurotransmitters are the chemicals that are released from the axon terminals of the pre-synaptic neurons of the synapse. These chemicals have receptors at the surface of the dendrites of postsynaptic neurons of the synapse. Binding of neurotransmitters to their receptors brings about the excitatory or inhibitory effect on the postsynaptic neuron. Accordingly, the action potential is fired. In this way, electrical signals are passed from one neuron to the next at the synapse. Acetylcholine is an example of neurotransmitters.
Answer:
C) predation
Explanation:
Such an insect would serve as a prey to a predator in a prey-predator relationship. Such relationship is a predation.
Predation is an act of feeding in a prey. The preys are weaker and smaller organisms which can easily be overpowered by the bigger predators.
When an insect evolves to resemble a plant twig, it is an evolutionary mimicry. Such organism that evolves must be prey. This presents the prey an evolutionary advantage for it to be evaded by the devouring predator. Mimicry is an evasive tactics.
In parasitism, one organism benefits while the other, the host, suffers from the relationship. Here, the parasite is lives inside the host. A mimicry won't apply here.
