Explanation:

Coexistence occur when individual occupying in a particular place are able survive with limited resources.

Dispersal - some of the lizard go hunting, they disperse themselves to various places to get resources.

Stability mechanism- this happen when individual stabilizes them selves in a particular habitat dealing with

environmental variations that may occur and drift them apart.

Equalizing mechanism - they all try to be at the same pace to avoid been out compete, even though some are stronger they equalize their energy for all to manage the limited resources.

Give two reasonsthat may account for the continuous firing of a<br> PostsynapticNeuron.
lyudmila [28]

Answer:

1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which  leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>

2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase)   that  metabolize activities of  cholinergic   neurotransmitters  e,g acetycholine at post synaptic cleft. leading to firing of action potential.

Explanation:

Neuron whose dendrites  transmits action potential to the  neuromuscular junction is called presynaptic neuron. While  neuron that  transmit action potential away from the neuronal synaptic junction, or from the neuromuscular  junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called  post synaptic  neuron.

The more  negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced

The inhibition of  activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to  continuous   excitatory activities  of cholinergic neurotransmitters   on  the receptors at the postsynaptic neuron, and the more  action potential
