What are the 9 characteristics that seperate humans from other things?

Breathing, we require energy, reproduction, adaptation, complexity, movement, homeostasis,  we produce waste, and DNA.

Define human biology.

the study of human life.

Define breathing as it applies to a characteristic of human biology.

Respiration (aerobic) - taking in oxygen.

Metabolism is the sum of all chemical reactions that occur.

Define require energy as a characteristic of human biology

food -> ATP

C6H12O6 + 6O2 -> 6CO2 + 6H2O

 l-> ATP

<- photosynthesis

Define reproduction as a human biology characteristic

Individual, cells, and tissues

(growth and repair)

Define adaptation as a characteristic of human biology

Responds to their environment; organisms make changes to achieve better survival

(ex. mutation)

Define complexity as it applies to human biology characteristics.

We have levels of organization (with respect to living things), composed of organic macromolecules: carbohydrates, lipids, and proteins. All of our cells are composed of carbohydrates, lipids, and proteins.

Define movement as it applies to the characteristic of human biology

We can have cellular movement, we have organelles which move.

 Define homeostatsis as it applies to the characteristics of human biology.

Maintaining a constant or consistent internal environment, regardless of what's going on outside.

(Ex. shivering, blood pressure, blood sugar)

Define produce waste as it applies to the characteristics of human biology

We produce waste by digesting food. Oxygen goes in and CO2 comes out. (Ex. blood goes out through the kidneys as urine, feces, heat which is the #1 waste producer).

Define DNA as a characteristic of human biology.

the genetic blueprint. DNA controls all the other characteristics of human biology. Without DNA there is no internal control.
