|
Spontaneous Generation |
Non-binding objects can give rise to living organisms. Which was proposed by Aristotle in 4th century BC, but disproved later in 16th(Francesco Redi) and 18th(Louis Pasteur) century. |
|
|
Scientific Method |
Method of research in which a problem is identified, relevant data is gathered, a hypothesis is formed from data, and then the hypothesis is tested. |
|
|
Hypothesis |
A tentative explanation for the observation based on previous knowledge, facts, and general principles. Includes "If" and "Then" in the statement. |
|
|
Biosphere |
The biological component of the Earth, which includes Lithosphere, Hydrosphere, and Atmosphere. |
|
|
Ecosystem |
A community of living organisms in conjuction with the nonliving components of their environment interacting as a system. |
|
|
Community |
Includes all the living components of a specific region. |
|
|
Population |
A group of organisms which belong to the same species that interbreed and live in the same geographical area. |
|
|
Organisms |
A living being |
|
|
Organ System |
A group of organs that work together to perform a certain task. |
|
|
Organ |
A collection of tissues joined in a structural unit to serve a common function. |
|
|
Cell |
Building blocks, the structural unit of life |
|
|
Organelles |
Within cells, which allow the cells to function properly. |
|
|
Element |
A substance that consists of just one type of atoms. |
|
|
Isotopes |
Different possible versions of each element. |
|
|
Molecule |
When two or more similar or different atoms join together chemically. H2 or CO(Carbon monoxide) |
|
|
Compound |
A molecule that contains at least two different elements. H2O or CO2 (Carbon dioxide) |
|
|
Non-polar Covalent Bonds |
Formed by two similar atoms |
|
|
Polar Covalent Bonds |
Formed by two dissimilar atoms |
|
|
Hydrogen Bonds |
Polar molecules such as water show particular positive and negative charges. The partial charges on a covalently bonded hydrogen atom attracts a different electronegative atom to form a hydrogen bond. |
|
|
Metabolism |
Energy, in the former of food, is transformed to maintain metabolic processes and for survival. |
|
|
Osmoregulation |
The process of regulating water potential in order to keep fluid and electrolyte balance within a cell or organism relative to the surrounding. |
|
|
Adapting |
Changing one's behavior to suit the circumstances |
|
|
Organic Chemistry |
Study of compounds containing Carbon. All organic/biological compounds contain Carbon and Hydrogen |
|
|
Biochemistry |
The study of chemical processes in living organisms |
|
|
Essential Elements of life |
Carbon, Hydrogen, Oxygen, Nitrogen, (C.H.O.N.), Calcium, Phosphorus, Potassium, and Sulfur |
|
|
Energy levels of the shell |
Orbitals form shells. Energy increases from inner shell towards outer shell. Electrons gain or lose energy when they jump from one level to another. |
