The lymphatic system includes areas of high concentrations of APCs, T and B cells.
<h3>What is the lymphatic system?</h3>
The lymphatic system is a branch of the circulatory system which consists of a system of organs , tissues, cells and vessels known as lymphatic vessels, which help transport the fluid, lymph around the body.
The lymphatic system contains high concentration of immune cells.
Therefore, the lymphatic system includes areas of high concentrations of APCs, T and B cells.

Answer: summation
Explanation:
The process which determine if an action potential will be generated or not depends on the combined effects of the signal inputs from multiple sources of synapse or from the repeated signals from the same synapse.
If the input signals reach the threshold voltage, action potential will be generated. (all –or –none principle).Therefore, this process is a determinant of the likelihood of action potential generation and it is called summation.
Summation is the ability to integrate multiple PSPs at multiple synapses.it is the process that determine if an action potential will be generated by combined effects of inhibitory or excitatory signals.
Based on the pathways and voulme of applied stimuli in the presynaptic neuron;
The signals can be temporal summation ( consecutive signals produced from the same synapse)where action potential of high frequency in the PSN generated action potential in the post synaptic neuron, which summate with one another. Or Spatial where signals inputs are from multiple presynaptic cells.
<span>An emulsion refers to a liquid dispersed in another liquid with which it is not soluble. For example, oil mixed with vinegar is an example of an emulsion with which oil remains suspended as droplets in vinegar, in which it is not soluble. An emulsifier helps to stabilize emulsions and aid in the mixing of the substances.</span>
Answer:
Reservoirs
Explanation:
Glaciers serve as reservoirs in the water cycle since they can store water for long periods of time. A biogeochemical or nutrient cycle is composed of
- reservoirs, in which the biogeochemical or nutrient is stored, and
- the several processes by which the biogeochemical or nutrient is cycled between its reservoirs.
