Humans impact the physical environment in many ways overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
The molecules which store and process genetic information is DNA - deoxyribonucleic acid.
Fossil fuel power burn carbon fuels such a coil,oil or gas to generate that drives large turbines that produces electricity by burning carbon fuel they produce large amount carbon dioxide.
Answer:
Posterior column mediates a pathway called as posterior column medial lemniscus pathway in central nervous which is responsible for mediating certain sensations like touch, vibration etc. Damage to the left posterior column unable to transmit signals to the primary somatosensory cortex in the gyrus and parietal lobe of the brain.
Explanation:
- The spinal cord and cerebrum is connected by some specialized tract called as white matter tract. These tracts are either ascending or descending.
- The another name of ascending pathway is known as medial lemniscus pathway.
- The origin of this pathway takes place within posterior column of the spinal cord.
- Posterior column medial lemniscus pathway is important as it transmit signals to the cerebrum which is responsible for generating impulse like vibration, touch etc.
- Thus damage to this column can't be able to transmit signals to different parts of cerebrum and thus impulse like touch, vibration,pressure etc will not generate.
