Focedure: 1. Study the three (3) patterns of population distribution (Bermuda, Cogon and Makahiya)
as shown in the Figure above. Solve for the area (A= L x W) given that the Length is
20cm and Width is 20cm.
2. Count the number of organisms in each population and record it on the table given
below.
3. Using the given formula below, compute for the density of each population.
DENSITY=
number of individuals
size of the area
Number of Organisms
Population Density
Table 1. Population Density

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

there is none because earth is stationary and flat.
