| Term | Definition |
|---|---|
| covalent bond | electrons being shared between two atoms to form a molecule |
| hydrogen bond | when a hydrogen atom is part of a polar covalent bond it's partial positive charge allows it to share attractions with other electronegative atoms, such as oxygen or nitrogen. pg. 24 |
| cohesion/ cohesive | the sticking together of particles of the same substance. ex: when water sticks to water |
| adhesion/ adhesive | the action or process of sticking to a surface or object. ex: when tape sticks to paper |
| polar | uneven sharing of electrons that causes partial charges |
| hydrophilic | having a tendency to mix with, dissolve in, or be wetted by water |
| hydrophobic | tending to repel or fail to mix with water. |
| non polar | even sharing of electrons to produce neutral (no charge) molecules |
| the six key elements that make up the majority of living tissues | (CHNOPS) carbon, hydrogen, nitrogen, oxygen, phosphorous, sulfur |
| the four major macromolecules found in cells | proteins, nucleic acids, lipids, carbohydrates |
| proteins | "the work horse of the body" jobs: transportation, movement, structure, immunity |
| nucleic acids | contain the genetic code (DNA) are passed down to offspring via reproduction |
| lipids | long term energy storage used to keep bodies warm and are major parts of the cell membrane |
| carbohydrates | short term/ immediate energy source made by plants and other organisms through photosynthesis |
| biology | the study of life |
| science | the study of the natural world |
| skills of a scientist | 1. observation 2. gather and organize data 3. communicate what you've learned |
| characteristics of life (there are 6) | 1. made of one or more cells 2. reproduce 3. requires energy 4. change, adapt, evolve w/ genetic code (DNA) 5. grow and develop 6. responds to stimuli |
| atom | the smallest bit of matter that retains the properties of an element |
| molecule | a group of two or more atoms held together by covalent bonds |
| bond | an attraction between two atoms resulting from the sharing of outer-shell electrons or the presence of opposite charges on the atoms. |
| macromolecule | a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer |
| electron | a subatomic particle with a single negative electrical charge |
| proton | a subatomic particle with a single positive charge |
| neutron | a particle that is electrically neutral ( has no electrical charge) |
| property | quality of an element |
| polarity | charged |
| subatomic particle | a particle smaller than an atom |
| solution= | solvent + solute |
| monomer | a molecule that can be bonded to other identical molecules to form a polymer |
| polymer | a substance that has a molecular structure consisting mostly or entirely of a large number of similar units bonded together |
| dehydration reaction | a chemical reaction that involves the loss of a water molecule from the reacting molecule |
| atomic nucleus | the region where the protons and neutrons are |
| if an atom is hydrophobic, why won't it mix with water? | The electrons in the atom are shared evenly making them neutral and unable to mix with water |
| atomic number | is the number of protons |
| number of neutrons= | mass-atomic number |
