Explanation:
Answer:
B. Positive feedback
Explanation:
The positive feedback or positive feedback mechanism occurs in smaller quantities compared to the negative feedback mechanism. Positive feedback, unlike negative feedback, ensures increased stimulus that causes imbalance, reinforcing it. Thus, positive feedback is not always beneficial, triggering, in some cases, detrimental effects on the body.
Although less than negative, positive feedback also plays an important role in our bodies. An example of this occurs when platelet release chemicals are activated in an injured tissue to attract more platelets, eventually forming a blood clot.
Answer:
The correct answer is nerve cells.
Explanation:
Cobalamine which is also known as vitamin B-12 which is very important for the human body. It helps in the synthesis of RBCs and plays an important role in protecting the nerve cells.
Vitamin B- 12 helps in myelin sheath synthesis and maintenance. This myelin sheath makes the outer covering of neurons and plays an important role in the protection of neurons and relaying of signals at high speed.
Deficiency of vitamin B-12 causes damage to myelin sheath which results in different neurological problems. Therefore the correct answer is nerve cells.
