The cause of the change in insect characteristics occurred when a few survivors of the 1st spray became resistant to the insecticide. When they had offspring, those insect babies are born with the trait that made them resistant to insecticide. This occurs when the parents pass on the trait to their offspring. The end result is that the insecticide is less effective and more insects survive.

Rudiy27
The hawk, a carnivore (animal meat-eater), is predating on the rabbit, an herbivore (plant-eater). So the hawk can be seen as the predator and the rabbit as the prey.
But another type of relationship important in Ecology is consumers. So producers are the plants that feed a food web. That makes the rabbits the primary consumers (herbivores) of these plants. Then the hawks become the secondary consumers (carnivores) of the primary consumers, by eating the herbivores.

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.
