Expert Solution
If we wants to perform the experiment to investigate the effect of different Colors of light of yellow red and clear cellophane and plant three seeds in each one.
This experiment is done on the basis of independent variables. In this process there is one dependant variable is light which can be used from sunlight or artificial light. The dependent variable is temperature, humidity and growth of plant.
In the independent variables the variables changed by its own or purposely changed the amount of light.
The amount light is measured as it is independent variables and amount of temperature and humidity is measured due to their variables. So both the variables can be controlled and measured. As there is clear cellophane which absorbs the visible light and red light remains as it is. If we use dubble red filter cellophane then red light is absorbed. Like this ways we can calculate amount of light and growth of plant.

You are designing an experiment to investigate the effect of
odor on alertness. In this experiment, 10 subjects will experience
the experimental condition (smelling peppermint) and another 10
will be given the control condition (odorless). You know that age
significantly affects the sense of smell, with people over the age
of 60 showing a decreased ability to identify odors. A total of 20
subjects of all ages (18-80) have signed up for the experiment. How
would you assign them to...

A physics professor wants to perform a lecture demonstration of
Young's double-slit experiment for her class using the 633nm light
from a He-Ne laser. Because the lecture hall is very large, the
interference pattern will be projected on a wall that is 6.0m from
the slits. For easy viewing by all students in the class, the
professor wants the distance between the m=0 and m=1 maxima to be
30cm .
What slit separation is required in order to produce the...

techniques, design an experiment to investigate a novel hypothesis
for the process of vesicle transport. The hypothesis proposes that
a network of defined microfilament tracts in the cytoplasm exist
(like railroad tracks!) and that are not visible under a microscope
and that do not stain with the regular histochemical dyes that are
available. These tracts are of distinctly different types and are
made up of proteins – each type of unique...

In a laboratory experiment to investigate the effect of sewage
effluent on the fecundity of freshwater shrimps (Gammarus
pulex) a number of populations of shrimps were placed into
large vessels with different concentrations of organic matter.
Females from each vessel were then dissected to see how many eggs
they were carrying.

A researcher conducts an experiment in a residence for senior
citizens to investigate the effect of floor type on the risk of
fall-related injury. For 24 randomly selected individuals in the
facility, she records the type of flooring (either standard
flooring or a new, rubber flooring that absorbs the impact of
falls) in their room and whether they sustained at least one
fall-related injury in their room over the previous two years. She
is interested in whether the rubber flooring...

An experiment was conducted to investigate the effect of
extrusion pressure (P) and temperature at extrusion (T) on the
strength y of a new type of plastic. Two plastic specimens
were prepared for each of five combinations of pressure and
temperature. The specimens were then tested in a random order and
the breaking strength for each specimen was recorded. The
independent variables were coded (transformed) as follows to
simplify the calculations: x1= (P-200)/10,
x2= (T-400)/25. The n=10 data points
are...
