German Scientist named William Roentgen.
Roentgen discovered X-Rays while researching at the University of Wurzburg in 1895. Roentgen noticed rays emanating from black paper and theorized as to what they were.
Answer:
The response to the question is a discrete random variable.
Explanation:
By definition of a discrete random variable we infer that the response can only take certain known values but the response shall be completely random. As an example when we toss a fair coin the out comes are discrete as only either head or tail is possible and the outcome is random meaning we cannot predict the outcome before hand.
Similarly an continuous random variable takes any value in a set and there are infinitely many possible values it can take. For example if we choose any real number between 1 and 10. Since the answers are infinitely many in number and are completely random.
Now in our survey we can infer that the responses shall be either "yes I smoked last week" or "No i didn't smoke last week". Hence the variables are discrete and random.

Answer:
spinal cord
Explanation:
In 1965 Melzack and Wall proposed the gate-control theory to explain the phenomena related to pain. This theory suggests the presence of a mechanism at the level of the central nervous system that opens or closes the pain pathways.
The transmission of afferent (sensitive) nerve impulses is modulated by a gate system, located in the posterior antlers of the spinal cord.
