<span>I suspect this question should read "How long does a red blood
cell live." A red blood cell lives for between 100 and 120 days. It
takes 7 days for a new red blood cell to develop from stem cells. Stem
cells are similar to base cells. They can also be seen as a general
template from which specialized cells are made. Stem cells can be taken
from a newborn baby's umbilical chord or extracted from an adult blood
donor's blood.</span>
Answer:
The excessive alcohol consumption of the mother.
Explanation:
Alcohol consumption during pregnancy harms the developing baby, the foetus. This is because alcohol passes from the mother's blood to the baby's blood and this affects the growth of the baby's cell.
This causes severe damage to the cells of the brain and the spinal cord.
FASD - Fetal Alcohol Spectrums Disorder is characterised by growth and developmental problems and it can range from mild to severe.
Example is the baby having small head, narrow eye and behavioural problems later in life.
