<h3>The inner lining of the tube like systems possesses the ciliated epithelium. The cells bear shorter hair like projections called cilia which beat and allow the movement of the particles. The fallopian tubes are lined with cilia and vibrate to move the egg or the mucus in the cavity</h3>
<u>Answer:</u>
<em>The purpose of genetically modified crops is increasing the food supply. </em>
<u>Explanation:</u>
<em>When crops are attacked by pests the yield of the crops reduces.</em> 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 <em>genes of plant species will make them pest resistant.</em>
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.<em> This feature can be pest resistance, chemical resistance, improved nutrient profile etc. </em>
