Answer:
At a level in the spinal cord
Explanation:
The gate theory was elaborated in 1965 by P.D. Wall and r. Melzack, to explain the influence of tactile skin stimulation on pain relief. It essentially admits that there exists in the medullar posterior horns (located behind the central canal of the spinal cord) a gate-acting neural mechanism that can control the passage of nerve impulses transmitted from the peripheral fibers to the CNS through the medulla.
The gate regulates the influx of nociceptive impulses even before a perception of pain is created. The variation in the passage of action potentials (nociceptive) that the gate produces is determined by the activity of the thick (A-alpha and A-beta) and thin (A-delta and C) fibers, as well as cognitive influences.
Answer:
Option E
Explanation:
Correlation and causation studies are two different things. Co-relation is a simple representation of relationship between two subjects A and B. It does not mean that A will be caused because of B or B will be caused because of A.
However, causation connects two variables “cause and effect.” The case of negative impacts produced by TV during childhood stage is more a cause and effect relationship than a co-relation
Hence, option E is right answer

Riparian zones can reduce the impact of water pollution is true.
The statement is true.
<h3 /><h3>What are Riparian zones?</h3>
The areas along the banks of rivers and other sources of surface water are known as riparian zones.
The floodplain and riparian buffers bordering the floodplain are included.
Riparian zones benefit streams, groundwater, and downstream land areas in numerous ways, both environmentally and recreationally.
Thus, the given statement is true.
