Figure 6. Population Distribution of Plants
Procedure:
1. Study the three (3) patterns of population distribution (Bermuc Cogon and
Makahiya) as shown in the Figure above. Solve for the area (A=LxW) 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.
Using the given formula below, compute for the density of each population
DENSITY=
number of individuals
size of the area
Number of Organisms

Guide Questions:
Q1. Compare the distribution patterns of the three (3) populations.
Q2. Which population has the greatest density?
Q3. What are the possible causes for the difference in population density?
Q4. What are the factors that could change the density of each population?

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

multiply it by 5 in order for you to understand i cant give an exact answer.
