We describe a bond having one end slightly positive and the other end slightly negative as being polar. Inductive effects. An atom like fluorine which can pull the bonding pair away from the atom it is attached to is said to have a negative inductive effect.
These genetically modified organisms (GMOs) are designed for many reasons, including: pesticide and disease resistance, drought/frost resistance, increased yields, enhanced nutritional content and as a way to produce drugs or vaccines at low cost on a large scale.
On average, farmers who planted GMOs used 37% less pesticide to grow more food, and those farmers made a 68% larger profit. The researchers also found that using insecticide-resistant crops led to 25% greater profit while using herbicide-tolerant crops led to only 9% greater profit.
