Variables, Graphs, and Scientific Method
what is X and what is Y
X: Independent
Y: Dependent
(REMEMBER!!!!!!! VARIABLES CAN BE DIFFERENT LETTERS IN SOME CASES)
Covalent Bonds vs Ionic Bonds
Covalent: formed by the sharing of electrons between two nonmetals
Ionic: formed by the transfer of electrons between a metal and a nonmetal
Molecule for water.
(Bonus points for the type of charge each atom has)
H20 (Hydrogen = positive, Oxygen = negative)
Which macromolecule is used to store short term energy?
Carbohydrates!
All organic compounds contain what element?
Carbon
Control vs Experimental groups..........????
Control Group: Baseline comparison that isn't used to support the experiment
Experimental Group: Group that receives special conditions and treatments that are being studied.
What is it called when water molecules bond together?
Hydrogen Bonding!!!!
(Cohesion...... I guess we can count it)
What does hydrophilic mean? What does hydrophobic mean?
Hydrophobic = Repels water, won't dissolve in it, etc.
Hydrophilic = Water absorbed, absorbing water, dissolves in it, etc.
True or False: DNA contains lipids and proteins
FALSEEEEEEE. it's nucleic acids
The process in which water is added to break down compounds.
(Bonus points if you can name the opposite process)
Hydrolysis.
Dehydration Synthesis is when water is removed to bring compounds together.
Keelan is testing plant growth. He has three plants. He uses water for one, oil for the other, and food dye for the next. Each plant is given the same quantity of liquid on the same day once a week. Each is in a point made of the same material with the same amount of soil. What are the independent and dependent variables? Bonus points if you can name the constants.
Independent: Liquid
Dependent: Plant Growth
Constants: Amount of liquid, pot material, soil amount, time given liquid.
What are the electrons on the outermost ring called? Bonus points if you can name the function
Valence electrons which are used for bonds
What is the property that allows water to climb up things?
Capillary Action + Adhesion
What is an enzyme an example of?
Protein
Amino Acids are the monomer for what?
Proteins!
Can you list the scientific method in order?
1) Ask a Question, 2) Do Background Research, 3) Form a Hypothesis, 4) Conduct an Experiment, 5) Analyze the Data, 6) Draw a Conclusion, and 7) Communicate Results
(if you said something similar it will count!)
For the most part, are electrons equal to protons?
Why is water a "universal solvent"
It can dissolve many things
Which macromolecule has the most elements.
(Bonus points if you can name the elements)
Nucleic Acids! (Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus)
Phosphate group, nitrogenous base, and ribose make up what.
Nucleic Acid
Black takes in more heat while white reflects heat.
How do you solve for neutrons?
Atomic weight minus the atomic number!
What is the monomer for a lipid
Fatty Acid and Glycerol
Which macromolecules are the most important?
Lol its all of them.
Chemical make up of glucose?
C6H1206 (I'm pretty sure if the ratio is the same regardless of number, it is still glucose)
