Cards in this deck (21)
- 1WHAT ARE THE PARTS OF AN ATOM?THE NUCLEUS IS MADE OF NEUTRONS AND PROTONS
ELECTRONS ROTATE AROUND THE NUCLEUS - 2WHAT IS A NON POLAR COVALENT BONDELECTRONS SHARED EQUALLY.
EXAMPLE: HYDROGEN BONDS - 3WHAT IS A POLAR BOND?ELECTRONS SHARED UNEQUALLY.
EXAMPLE: WATER - 4WHAT IS AN IONIC BOND?WHEN HIGH ELECTRO-NEGATIVITY STRIPS VALENCE AWAY FROM ANOTHER ATOM.
EXAMPLE: SODIUM CHLORIDE - 5WHAT IS A HYDROGEN BOND?HYDROGEN BONDS OCCUR WHEN A POSITIVE HYDROGEN BOND ATTRACTS TO A NEGATIVE ATOM.
EXAMPLE: WATER, DNA - 6WHAT IS A CHEMICAL REACTION?REACTIONS OCCUR WHEN TWO OR MORE MOLECULES INTERACT AND THE MOLECULES CHANGE.
- 7WHOS GOING TO ACE THIS TEST TODAY?YOU OF COURSE! KEEP WORKING HARD, YOU ARE DOING GREAT! :)
- 8HOW DOES A HYDROGEN BOND RELATE TO WATER?HYDROGEN ATTRACTS THE H ATOMS TO THE O ATOMS. HYDROGEN BONDS ARE THE GLUE OF WATER!
- 9WHAT ARE THE PROPERTIES OF WATER?-WATER IS LIQUID AT ROOM TEMP; drinking, bathing, cooking
-TEMP OF WATER RISES AND FALLS SLOWLY; prevents drastic changes
-HIGH HEAT OF VAPOR; body doesnt overheat
-ICE IS LESS DENSE THAN LIQUID WATER; so ice floats
-WATER MOLS ARE COHESIVE; blood vessels - 10WHAT IS AN ACID?INCREASES THE HYDROGEN CONCENTRATION OF A SOLUTION
- 11WHAT IS pH?POWER OF HYDROGEN!
- 12WHAT IS BASE?REDUCES THE HYDROGEN ION CONCENTRATION OF A SOLUTION
- 13DEFINE SOLUTETHE MATTER THAT DISOLVES IN SOLUTION
- 14DEFINE SOLVENTTHE MATTER DISSOLVING SOLUTE
- 15DEFINE SOLUTION2 OR MORE SOLVENTS MIXED TOGETHER AND UNIFORMLY DISPERESED.
MAINLY THE RESULT OF FLUID, SOLID OR GAS BEING DISSOLVED IN A LIQUID. - 16WHY IS CARBON IMPORTANT FOR LIVING ORGANISMS?CARBON STICKS TO ITSELF. CREATING LONG CHANGES OF COMPLEX MOLECULES, IMPORTANT IN THEIR OWN FUNCTIONS. ALL LIFE ON EARTH IS BASED ON CARBON.
- 17WHAT IS THE FUNCTION AND SUBUNIT OF CARBOHYDRATES?THE FUNCTION OF CARBS IS A SHORT TERM ENERGY STORAGE.
SUBUNIT: SIMPLE SUGARS - 18WHAT IS THE FUNCTION AND SUBUNIT OF NUCLEIC ACID?TO STORE AND TRANSMIT GENETIC INFORMATION. EXAMPLE: NUCLEOTIDES
- 19WHAT IS THE FUNCTION AND SUBUNIT OF PROTEIN?TO SUPPORT ENZYMES AND TRANSPORT DEFENSE, TO PUT HORMONES IN MOTION. SUBUNIT: AMINO ACIDS
- 20WHAT IS THE FUNCTION AND SUBUNIT OF LIPIDS?CONTAIN MORE ENERGY PER GRAM THAN OTHER BIOLOGICAL MOLECULES.
SUBUNIT: FATTY ACIDS - 21HOW IS DNA AND RNA ALIKE AND DIFFERENT?DNA AND RNA ARE BOTH MADE UP OF POLYNUCLEOTIDE STRANDS. DNA HAS 2 STRANDS. RNA ONLY HAS 1.
