Answer: The correct answer to the question is option C
BECAUSE YOU HAVE HAD ONE CHILD WITH TAY-SACHS,YOU MUST EACH CARRY THE ALLELE.ANY CHILD YOU HAVE HAS A 25% CHANCE OF HAVING THE DISEASE.
Explanation: Tay- Sachs is a rare disorder that is inherited,it is characterised by a progressive destruction of the nerves of the brain and spinal cord.its onset is from around 6months of life to around 4-5years of age when the child affected eventually dies.
A Child that have Tay-Sachs experiences problem with coordination,muscle contraction, must stiffness and weakness.there is also difficulty is speaking, swallowing, wasting(uncontrolled weightloss), hearing loss,seizure, and vision loss.
Since the parents of the child in the question claims they don't have Tay- Sachs and no one in the family has it but they came down with a child having Tay-Sachs and one of the major factors to Tay-Sachs as stated above is heredity,the main point to counsel the couples on is that because they have had one child with Tay-Sachs,they most each carry the allele which is obviously recessive so any child they had have has 25% chance of having the disease.

A voltaic cells/ Galvanic cell uses a spontaneous reaction to generate electrical energy in this type of cell, the system does work on the.
This is the spontaneous chemical reaction that produces an electrical current through an outside circuit. These cells are important because they are basic for batteries that fuel modern society. it is occurs with no outside intervention.
This is used the energy released during a spontaneous red-ox reaction to generate electricity. That reaction will have a negative value of gibb's free energy, delta- G. Electrochemical cell is often called a voltaic cell after its inventor the Italian physicist alessandro volt.
