What is the correct pathway for air entering the human respiratory system?

SpyIntel [72]

Air enters into the body through nose and proceeds to pharynx or windpipe afterwards it proceeds down and reaches to larynx the voice box and continue to proceed to trachea which is surrounded by rings so that by air pressure it cannot be collapse from there a divides into two side left and right bronchus then it conducted towards bronchioles which is the pathway to alveoli at last it reaches to its Final Destination (not that movie....hahah) which is alveoli where the exchange of gases takes place

Describe two forms of mechanical weathering.

GalinKa [24]

1.Frost Wedging (Freeze-Thaw)

Water expands by 9 percent when it freezes. As it expands, it exerts up to 4.3 million pounds per square foot of pressure. Since water seeks low points, repeated freezing and thawing can lead to deep vertical fissures as cracks are extended downward. Cracks that allow entry of roots lead to similar wedging.

2.Crystal Formation

Crystal formation cracks rock in a similar way. Most water contains dissolved salts. When water in rock fissures evaporate, the salt concentration increases, which leads to crystallization. This occurs in arid regions where the humidity fluctuates widely, so that the salt can be redissolved and carried into new fissures.

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
