Answer:

Three factors are used.

The availability of sunlight.

The distance from shore and

The water depth.

Explanation:

Availability of Sunlight 

The photic zone is the upper part of the ocean into which sunlight penetrates.

Distance from Shore 

The intertidal zone is the strip of land where the land and ocean meet and overlap, or the zone between high and low tides.

The neritic zone is the marine-life zone that extends from the low-tide line out to the shelf break.

The oceanic zone is the marine-life zone beyond the continental shelf.

Water Depth

The pelagic zone is open zone of any depth. Animals in this zone swim or float freely.

The benthic zone is the marine-life zone that includes any sea-bottom surface regardless of its distance from shore.

The abyssal zone is a subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight

Give two reasonsthat may account for the continuous firing of a PostsynapticNeuron.

lyudmila [28]

Answer:

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

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
