Answer:
Hydrogen
Explanation:
Hydrogen is the non-mineral nutrient, that is essential for photosynthesis.
Carbon, Oxygen and Hydrogen are the non-mineral nutrients.
Answer:
Energy from the sun is transferred to Earth's surface. Some of that energy is then transferred to the air above the surface. The closer a location is to the equator, the more energy it receives from the sun. Therefore, a location's air temperature is affected by its distance from the equator.
Explanation:
Wells, tube-wells, rivers, lakes, dams etc. Methods of management of water resources include rainwater harvesting, construction of bawris and khadins and water harvesting structures on the level terrain.
Answer:
The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.
Explanation:
Chemical composition of the Sun and the movement of galaxies.
Astronomers are scientists who study the universe and the objects within it such as the sun, galaxies, stars, planets, star forming regions, and the evolution of the universe. Chemical composition of the Sun and the movement of galaxies are the types of evidence that astronomers use to estimate the age of the universe and stars. Astronomers detect the movement of galaxies by viewing its light spectrum. Astronomers can measure the expansion rate of the universe accurately by taking the measurements of many galaxies. Also, the chemical composition of the sun gives astronomers some idea about the age of the universe and stars.
