Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world's growing population.
non-metals gain electron and metals lose electrons,
<span>Iron is a metal, so when it reacts it loses an electron becomes a
cation and form ionic bonds. Hydrogen is a non-metal, it gains an electron when
