Meaning of Life
This is the definition of Biology.
The study of life
1st step in the scientific method
Define the problem
or
Ask a question
These are the 3 subatomic particles and their charges
Electrons, negative
Protons, positive
Neutrons, neutral
When atoms come together to make a molecule, or when a molecule breaks up into separate atoms
Chemical reaction
These are the 4 building blocks of life
Proteins
Lipids
Carbohydrates
Nucleic acids
The ultimate source of energy for life on Earth
The sun
2nd step in the scientific method.
Research
This is the type of bond that occurs between a positively charged ion and a negatively charged ion
Ionic bond
These are the atoms that come together to form a molecule.
Reactants
This element serves as the "backbone" for the building blocks of life.
Carbon
Cytology
3rd step in the scientific method.
Form a testable hypothesis
Valence shell
These are the molecules that result from reactants coming together
Products
This building block helps form the structure of tissues and organs, carries out chemical reactions in the body, and can act as chemical messengers.
Proteins
This is the study of genes and heredity
Genetics
4th step in the scientific method
Test hypothesis
This is the type of bond that occurs between 2 or more atoms sharing electrons in their valence shells
Covalent bond
This is the first law of thermodynamics
Energy cannot be created or destroyed; it can only be transferred or transformed.
These are the building blocks of proteins.
Amino Acids
List of 3 out of 5 characteristics of living things
Growth
Reproduction
Organization
Response
Requires energy
5th step in the scientific method
State your conclusions
This provides the most stability to an atom
The octet rule. When the valence shell is completely full (8 electrons) or completely empty.
This is a type of protein that changes the rate of a chemical reaction.
Enzyme
This is the type of bond that exists between amino acids
Peptide bonds
