c) a babys umbilical cord can be used to treat the same baby, if they are bord with blood disorders, such as leukemia

d) preserving the babys umbilical cord can be useful to help a sibling who may need stem cell transplant.

3. What are conditions that affect male or female reproductive systems that in Vitro Fertilization would help with?

Answer 1

5. Neuralation is the process theough which neural plate transforms into neural tube.
The neural plate eventually differentiates into the brain and spinal cord.
Vitamin B12 defiency during early stages of pregnancy in mother can lead to failure of neuralation. One such birth defect caused in spina bifida which is failure to develop the spinal cord.
SPINA BIFIDA occurs during fetal development when an embryo is NOT exposed to adequate levels of VITAMIN B12 during neurulation.
1. Stem cell are haemopoetic cells that give rise to all types of blood cells.
An inborn error of blood disorders will affect the stem cells too.
So the correct option is c

2. Superovulation is medical induction of ovary to produce more than one egg.
It can cause adverse effects such as ovarian torsion, multiple births, ovarian hyper stimulation.
so correct answer is c

3. in vitro fertilisation helps to
