1) Used to assess foetal growth and detect abnormalities such as spina bifida etc. 2) Useful in diagnosing kidney stones, gall stones, cirrhosis, obstructions in intestine, oviducts, uterus etc. 3) To measure blood flow through the heart, arteries and veins based on a phenomenon known as Doppler E..

a) Local species diversity is directly related to the efficiency with which the predators prevent the monopolization of an environmental area by any species. b) Predation keeps the prey population under check, so as to maintain an ecological balance. c) Weak and less efficient members in the prey ..

Significance of Respiration - Respiration is an important process in nature. It is a process by which the solar energy trapped by the plants in the food can be utilised. The organic compounds are broken down to release energy. This energy is in the form of ATP molecules and is made availa..

Respiration is an important process in nature. It is a process by which the solar energy trapped by the plants in the food can be utilised. The organic compounds are broken down to release energy. This energy is in the form of ATP molecules and is made available for all the vital activities of the ..

Mitosis becomes significant for the following reasons. Mitosis forms two daughter cells which will have the same chromosome number and same genetic material as the parent cell. Daughter cells formed from mitosis are genetically identical to their parent cell and no variation would be intr..

Variations provide the species a way to survive and adapt to the changing environmental conditions. Since there are variations, nature can choose the best suited individual and allow the species to multiply further. Thus, natural selection is possible only because of variatio..

Competition is extremely important in determining the distribution of closely related species. essential in determining habitat range and speciation..

Pollination leads to fertilisation, resulting in the production of seeds and fruits, thus ensuring continuity of life...

Photosynthesis is the only process which produces enormous quantities of organic matter for sustaining the life on this globe. It is the only known method of manufacture of organic food from inorganic raw materials. Animals including man are directly or indirectly dependent on photosynthetic ..
