Effect of osmosis on cells:
-Osmosis is the movement of water across a cell membrane. Cells use osmosis to maintain concentration equilibrium (the concentrations of solute inside and outside the cell are equal). Changing the amount of water allows the cells to achieve equilibrium.
Effects of osmosis on tissues:
-Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up, and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.
Hope this helps.
Answer: Increase
According to the competitive exclusion principle, when two or more species in an ecosystem are competing for the same resource. The one which has undergone favorable adaptation and more competing will be likely to derive those resource than the one which has not undergone adaptation or less adaptive to the environment and less competing. Squirrels and chipmunks compete for the same food source and this food source became scare one of the two species is likely to disappear according to the competitive exclusion principle because the degree of competition between two species will increase.

Answer:
See the answer below
Explanation:
The stock solution of Gentamycin has a concentration of 5 mg/ml while each plate needs to contain 50 micrograms/ml of Gentamycin.
5 mg/ml = 5000 micrograms/ml
There is a need to dilute the stock antibiotic solution in order to arrive at 50 micrograms/ml. Using the dilution principle;
m1v1 = m2v2
5000 x 1 = 50 x v2
v2 = 5000/50 = 1000 ml
<em>Hence, in order to prepare 50 micrograms/ml, 1 ml of the stock Gentamycin should be taken and diluted with 999 ml of distilled sterilized water. 1 ml of the diluted Gentamycin will then be added to each agar plate while they are still in the molten form at a warm temperature.</em>
