Macromolecules
Glucose, and galactose belong to this type of carbohydrate monomer.
Monosaccharides
These six elements necessary for life can be remembered as CHONPS.
What are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur?
A student writes, “The liquid is green and has a sweet smell.” This type of observation does not require numbers.
What is a qualitative observation?
In an experiment, this is the factor deliberately changed by the scientist and is usually placed on the X-axis.
Independent Variable
If a monomer is like a single brick, this larger structure would be the brick wall.
What is a polymer?
This offers zero calories per gram
Nucleic Acids
Going across the periodic table means moving through these, while moving up and down means moving through groups.
Three measurements are 10.1 g, 10.1 g, and 10.2 g, but the accepted value is 15.0 g. The measurements demonstrate this quality but not accuracy.
What is precision?
Students test whether different drinks affect running speed. The type of drink is changed, while running speed is measured. Running speed is this variable.
Dependent Variable
Amino acids join together by peptide bonds to form this protein polymer.
What is a polypeptide?
This macromolecule provides 9 calories per gram, more than twice the energy per gram of carbohydrates.
Lipids
Two elements are in the same group on the periodic table. According to your notes, they have the same number of these outer electrons.
valence electrons
The ground is wet” is an observation. “It must have rained” is this because it uses the observation to make a possible explanation.
What is an inference?
A plant experiment includes one group receiving the normal amount of water while other groups receive different amounts. The normally watered plants make up this group.
Control Group
Enzymes, antibodies, hormones, receptors, and some structures in your body all belong to this incredibly diverse macromolecule group.
What is a protien
A molecule contains a phosphate head and two fatty-acid tails. Its head interacts with water while its tails avoid water.
What is a phospholipid?
An element has seven valence electrons and is highly reactive because it needs only one more. It belongs to this periodic-table family.
What are the halogens?
A scientist discovers new evidence that changes our understanding of a phenomenon. This is acceptable because scientific understanding does this as new findings are made.
What is builds/changes with new evidence?
During the start of the year Ms.Marcoux had you sign a contract and a syllabus. If you read the syllabus what was the last thing Ms.Marcoux asked you to do and turn in that was seperate.
Drawing of W-Coyote
A cell membrane can control what enters and leaves because two layers of these molecules create a selectively permeable barrier.
What are phospholipids/a phospholipid bilayer?
Carbohydrates and proteins both provide 4 calories per gram, yet the body typically uses one first and saves the other as a last resort. Name them in that order.
Carbohydrates & Proteins
One family desperately wants to lose its single valence electron, while another is already stable with a full outer shell. Name both families.
Alkali and Noble Gases
One describes patterns in nature and answers HOW, while the other organizes evidence to explain WHY. Contrary to a common misconception, one does not eventually turn into the other.
What are a scientific law and a scientific theory?
A scientist changes fertilizer type to determine its effect on plant growth. One group gets no fertilizer. Name the IV, DV, and control group.
What are fertilizer type, plant growth, and the no-fertilizer group?
Macromolecule riddle: I am not the body's first choice for energy. My monomers are amino acids. I may act as an enzyme, antibody, hormone, receptor, or transporter. Who am I?
What is a protein
