The double fortification process involves adding iodine and iron to salt. It is a method used to fight micronutrient deficiencies in developing countries. Iron and iodine are two of the most important micronutrients involved in cognitive function, maternal and infant survival and human productivity. This is a cost-effective method that ensures that the population receives these nutrients without having to change their eating habits.
Answer:
A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components.
Answer:
When the females tend to form a solitary group, the adult males have an advantage of mating with females in different social groups thus enhancing on the productivity of the species.
Explanation:
When both the sexes of the species tend to make a group, the males and the females of the group have to mate with the members of that particular group and hence the males have restricted mating options which reduce the size of the herd. When the females have a separate social group, the males can mate with the members of different groups and raise the herd size in a short period of time. This helps in the increase in the population size and also helps in avoiding inbreeding depression which happens among small grouped animals.
