Question

Medical Science has understood that there are over 200 types
of cancer. Why so? The answer is easy> There are over 200 types
of cells in the human body and all of them can become cancerous.
Normal healthy cells divide and die as they should, but you may
ask "How many time?" The average number of times normal
healthy cells divide is known as Hayflick limit. It was named
after Dr. Leonard Hayflick who in 1965 noticed that cells divide
a specific number of times before one division stops. Its Average
was between 40 and 60. If someone took every cell in his body at
the time he was born, if accounted for all the cells that he would
produce and so on, multiplied number by the average time it takes
for the cells to die, he gets what is known as Hayflick limit. The
maximum number of years one can theoretically live. That would
be 120 years.

C. Answer is the following questions:

i) what is Hayflick limit?

ii) Who was Dr. Leonard Hayflick?

iii) Give a suitable title to the passage?​

Answer 1

The Hayflick limit, or Hayflick phenomenon, is the number of times a normal human cell population will divide before cell division stops. The concept of the Hayflick limit was advanced by American anatomist Leonard Hayflick in 1961, at the Wistar Institute in Philadelphia, Pennsylvania, United States

Answer 2

Answer:

The Hayflick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.
