Table 3
A linear graph is one where there is a steady change in the value on the y-axis with a steady change in the value on the x-axis. The first table will produce a positive sloped straight line that has an increase of 5 in the value of distance with each increment in the time value.
Table 2 will produce a graph where there is a decrease of 2 in the value of distance with an increase in the value of time.
Table 4 will produce a graph where the line is horizontal; the y-value does not change with time.
Table 3 has a graph which has to move up and down to accommodate the decreasing and increasing values, so it will be non-linear.
Water diffuses into the skin via sweat ducts which alters the electrolyte balance. electrolytes can be salts like sodium and potassium. This alters the stability of neurons causing blood vessels to constrict therefore decreasing the amount of fluid in the fingers which would normally give the skin tension. The decrease causes wrinkles.
The answer is the solution is hypotonic solution since there are less solute in the solution , indicating that there is more water in solution .
sorry if my answer was wrong
