Here is the answer that would best complete the given statement above. <span>The physical, chemical, and biological laws that operate today also in geologic past. This statement relates to the principle of </span>uniformitarianism. Hope this answers your question. Have a great day!
<span>Central nervous system
Sympathetic nervous system
The neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions. </span>
<span>Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions.<span>

The tick is considered the vector in the chain of infection.
Generally, vector organisms are organisms that are capable of transmitting disease pathogens from infected organisms to uninfected ones either directly or indirectly as a result of their activities.
Ticks are parasites that feed on the blood of vertebrate animals such as deers and humans. When they feed on the blood of animals with certain infections, the pathogens for such infections are sometimes carried in the guts of the parasites and these are transferred to the bloodstream of the next animal that would be their host.
A good example of this is Lyme disease.

I'm not 100% sure, but I'd say the availability of vaccines and medicine.
