The correct answer is (b) The water has a lower boiling point than salt.

The separation of salt from water is carried out by the process of distillation. The boiling point of water is lower than that of salt so the water converts into steam on heating and the salt remains in the vessel. When salt is mixed in water, there occurs a phenomenon called elevation in boiling point of water but the change is very less as it cannot be observed. Even if there is a elevation in boiling point of the water it is lower as compared to the boiling point of salt.

What is the purpose of genetically modified crops?

Sliva [168]

Answer:

The purpose of genetically modified crops is increasing the food supply. 

Explanation:

When crops are attacked by pests the yield of the crops reduces. The natural pest tackling adaptations of the plant is not just enough to check the invasion of crops by pests. Introducing feature of pest resistance into the genes of plant species will make them pest resistant.

Genetic modification is the method used to achieve this objective. In genetic modification a previously absent feature is introduced into a plant species by various scientific techniques. This feature can be pest resistance, chemical resistance, improved nutrient profile etc.
