Based on the result in this
experiment, the mobile phase rose up on the TLC plate then dragged the ink from
the marked dot up along the TLC plate, which is the light pink pigment whose Rf
was 0.98 had the greatest affinity to the mobile phase. Moreover, the pigment
that was closer to the marked dot was more attracted to the stationary phase,
which is the dark pink spot that had an Rf of 0.72 and had a greater affinity to the
stationary phase.
Answer:
Explanation:
It's simply law of osmosis.
In osmosis solvent particles move from lower solute concentration to higher solute concentration until both the solution acquire the same concentration. So when a plant cell is kept in hypertonic solution (having more solute concentration), the solvent particles move outside the cell causing it to shrink, which is also known as plasmolysis of cell.
When a plant cell is kept in hypotonic solution (having less solute concentration), the solvent particles move inside the cell causing it to swell up which is also known as deplasmolysis. But due to the presence of cell wall, plant cell can not burst. Cell wall is a very stratchable boundary made up of cellulose mainly which makes the plant cell non-collapsable (but animal cells can burst in hypotonic solution due to absence of cell wall)

Explanation
Moisture is a great environment for bacteria to grow, the moister the environment is the more the bacteria will thrive, thinking about this lower moisture levels will result in lower microbial diversity.
The small intestine has higher ph than the stomach, this means that the bacteria there thrive in higher ph than the stomach bacteria.
Normal microbia in the skin usually acts as the first barrier against pathogens, while we have normal microbia it will protect us and will be less likely to get skin pathogens.
Immunocompromised patients are people that have received treatment to reduce their immunological system capacity, this means that even though this is done to battle a disease, another opportunistic infection can appear and take advantage of the fact that the defenses are low.
