Describing Competition

irinina [24]

Whales have horizontally positioned tales opposed to fish and they swim in an up and down type of motion to move, where as fish are the exact opposite flexing and turning their body left and right with their vertical tale to move.

Whales have bigger mouths to eat large schools of krill (their main source of food)

And also, whales are mammals, and breathe with their lungs, whereas fish use gills to breathe underwater. I hope this helped! Please mark Brainliest!

Hair Coloring Experiment

leva [86]

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

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

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.

In the exposed example, the independent variable is the red hair coloring

- Red Hair Paint

- L’Oreal

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.

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

CONSTANTS

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

In the exposed example, the constant variable is the type of hair, curly or straight.

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.

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

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.

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,

- 10 blonds,

- 10 brunettes,

- 10 with black hair

- 10 with red hair
