The energy in all food webs and chains can, in fact, be traced back to the sun. The sun produces different types of electromagnetic energy waves, one of which is visible light. This type of energy cannot be used by most organisms; except for plants. They convert light energy into chemical energy via the process of photosynthesis. This chemical energy is now available to pass through the trophic levels of food chains.
The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion. Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms - including all plants and animals - release energy from their food using respiration.-BBC.CO.UK
The answer to your question is c, because during photosynthesis, glucose and oxygen is mad from water, light, and CO2
Explanation:
Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.
Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.
= 300 g
Thus, we can conclude that weight of Tris-HCL required is 300 g.
