Answer: Consumers
Explanation: Pumas are carnivores meaning they only eat meat, herbivores eat plants, and omnivore eat both meat and plants but still eat plants. Producers are more like plant they product nutrients, which herbivores or omnivores eat.
The synapse between neuron X and the postsynaptic neuron is most likely a cholinergic synapse. Neurotransmitters from neuron X bind to the postsynaptic membrane receptors that are connected to sodium channels. Positive sodium ions(Na+)enter the cell but are not enough to make the membrane potential reach the threshold. This is an excitatory synapse.
The synapse between neuron Y and the postsynaptic neuron is an inhibitory synapse. The most common inhibitory neurotransmitter is GABA(Gamma amino butryric acid). When GABA binds to the postsynaptic receptor, chlorine channels are open. Chlorine(Cl-) is an anion that is negatively charged. When chlorine enters the cell it makes the potential go below the resting membrane potential.
The synapse between neuron Z and the postsynaptic neuron has pretty much the same mechanism as the synapse between neuron X and the postsynaptic neuron but more sodium ions enter the cell so an action potential can be generated.
Apparently it’s called the ovum
