Answer:
In the decolorization step alcohol is used which destain the gram-negative bacteria but not gram-positive because alcohol degrades the LPS cell wall of gram-negative bacteria which allow the crystal violet to moves out of the cell.
So if we use too little alcohol then the alcohol will not able to decolorize all the gram-negative bacteria and most of the cell in the culture will appear violet or purple because crystal violet retained in the cell wall of bacteria.
So the sample of gram-negative bacteria will appear as gram-positive bacteria under the microscope.
Answer:
Photosynthesis consist of two types of reaction 1 light dependent reaction 2 light independent reaction or dark reaction.
Explanation:
light dependent reaction
light dependent reaction or light reaction occur in the thylakoid of granum of chloroplast.During light reaction light energy is absorbed by various pigments of the photosystem and is finally converted into chemical energy.
During light reaction water is split in presence of sunlight to form H+ and OH- ions.The OH- ions releases electron.The released electron is then transported through various electron carriers resulting in the formation of ATP molecule by cyclic photo phosphorylation and NADPH by noncyclic photophosphorylation.
Light independent reaction
Light independent reaction or dark reaction occur in the stroma of chloroplast.The ATP and NADPH that is formed during light reaction is used as 3:2 ratio for per molecule of glucose production.

Answer: Natural resources are Earth materials used to support life and meet the needs of people. Any organic material used by humans can be considered as a natural resource. Natural resources include oil, coal, natural gas, metals, stone, and sand. Air, sunlight, soil, and water are other natural resources.
Or
Natural resources are resources that exist without any actions of humankind.
