Base your answers to questions 71 – 73 on the information and table below and on your knowledge of
science.
A farmer grows and sells flowering plants. The best-selling plants are the ones with the
most blossoms. The farmer reads an advertisement for a plant food saying that it will make plants
grow faster and taller. The farmer predicts that taller plants will have more blossoms and
performs the following experiment to test this hypothesis.
Two groups of 10 plants each are grown in identical pots filled with equal amounts of
identical soil. The amount of sunlight, the room temperature, and the amount of water are held
constant for both groups. Group A is given plant food at regular intervals according to the
instructions on the package. Group B is not given plant food.
The farmer observes the plants after 15 weeks of growth. The results are recorded below.

Use the information below to answer question 85.
The Sun as a Source of Energy
Much of the energy on the Earth can be traced back to the Sun. Let’s look at an example of this. You
turn on the television, which converts the electrical energy in the wires into sound and pictures. But where did
the electrical energy come from? Your power company might burn coal or oil to generate the electrical energy
that they sell you. When the fuel burns, it creates lots of heat energy which is used to create steam. The steam
is made of fast-moving water molecules with lots of kinetic energy. The steam turns a turbine, a device that
generates electricity. The oil or coal that begins this process is ancient, organic material made of dead plants
and animals which heat and pressure have transformed into hydrocarbon compounds. The energy stored in
these compounds is similar to the energy stored in plants and animals that are still alive; all of this energy comes
from the Sun!
85.
Give another example of a series of energy transformations that can be traced back to the Sun.
