Hair Coloring Experiment
leva [86]

The independent variable (hair<em> colorin</em>) causes a <u>response</u> in the dependent one (colorin <em>effectiveness)</em>. The constant variable <u>can not change</u> (<em>curly or straight</em>), the control variable is <u>kept constant</u> (<em>time and environmental conditions</em>). The experimental group receives the <u>treatment</u> (<em>40 students</em>).

------------------------------------------------

INDEPENDENT VARIABLE

Refers to all the variables in an experiment that provoke a response in another variable. The independent variable is modified to analyze its effects on another variable. The researcher changes on purpose the independent variable to observe the response of the dependent variable.

<em>In the exposed example, the independent variable is the red hair coloring </em>

<em>- Red Hair Paint</em>

<em>- L’Oreal</em>

DEPENDENT VARIABLE

Refers to the variable, which response depends on any change in the independent variable. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable.

<em>In the exposed example, the dependent variable is the coloring effectiveness, seen through how well the coloring takes and lasts. </em>

CONSTANTS

This variable does not change during the whole experiment and under any circumstance. It <u>can not change</u>.

<em>In the exposed example, the constant variable is the type of hair, curly or straight. </em>

CONTROL

Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.

<em>In the exposed example, the controlled variables are the exposure time to the colorings and environmental conditions, such as temperature, humidity, etc.</em>

EXPERIMENTAL GROUP

The experimental group receives the treatment. The researcher apply different treatments to the experimental groups to observe how they affect the dependent variable. There can be several experimental groups.

<em>In the exposed example, the general experimental group is the 40 students' hairs. Because coloring does not have the same effect on different hair colors, the experimental group includes,</em>

<em>- 10 blonds, </em>

<em>- 10 brunettes, </em>

<em>- 10 with black hair</em>

<em>- 10 with red hair</em>

Totipotent stem cells have the ability to develop into any kind of cell found in the human body.
When the sperm fertilizes the egg, creates the zygote which is the fist totipotent cell. After that, in the first cell divisions more totipotent cells are produced. Within several days, these totipotent cells produce even more totipotent cells and after four days the cells begin to specialize.
