Answer:
The correct answer is violet/ purple.
Explanation:
Gram staining is performed to distinguish between gram-positive and gram-negative bacteria. The first stain or dye which is used in gram stain is crystal violet. So after adding this dye, all cells will be colored purple.
So when we stop after the addition of first dye then all the cells will appear purple/violet because all the cells will contain crystal violet in its cell wall which can be seen under the microscope. So we will not be able to distinguish between gram-positive and gram-negative bacteria. So the correct answer is purple.
Simple diffusion, which is different from facilitated diffusion.
We reject the options a) and b) since the question says that the data supports "equally" both cases - so we have no basis for making a choice either way.
Further, in science the decisions are reached based on facts, not voting, so we also reject the answer D .
We are left with the answer C and this is also the best practice in science - when unsure, leave it as a hypothesis.
