True??? I think u don’t need to put the answer I gave u but it’s just my thought
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.
Answer: B. The endoplasmic reticulum

The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.
Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.
Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.
DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.
Both DNA and RNA are termed as the genetic molecules of life.
