Sci. Method
The four (4) parts of an experiment that must be present in order for an experiment to be valid.
What are the Control / Treatments / Replication / Randomization?
What are the elemental symbols for the following elements:
Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur, Phosphorus?
What are C for carbon; H for hydrogen; O for oxygen; N for nitrogen; S for sulfur and P for phosphorus?
Glucose, Fructose & Glactose are examples of what organizational level of carbohydrates?
What are monosacchrides?
Membranes function to:
What is to keep the good things in and the bad things out, or to maintain particular concentrations of matter across the membrane?
What conditions exist if a cell is in a hypertonic solution?
What is the concentration of solutes outside the cell are higher than the concentration of solutes inside the cell?
What are the two (2) types of controls that an experiment may have?
What are positive and negative?
What value is measured to give an idea of how acidic a solution might be?
What is pH?
Glucose, Fructose & Glactose all have the same chemical formula but different shapes, they are therefore examples of what class of molecules?
What are isomers?
What is the principle component of membranes?
What are phospholipids?
What conditions exist if a cell is in an isotonic solution?
What is the concentrations of solutes on both sides of the membrane are equal?
What is the reason or rational behind the idea that an experiment must be replicated?
What are variations in responses from the treatments, in other words the same treatment may elicit different values?
What are the elemental symbols for the following active groups: any acid; any base; a carboxyl group; a hydroxyl group; a sulfhydryl group
What are H(+) for acids; -OH for bases; COOH for carboxyl groups; -OH for hydroxyl groups and -SH for a sulfhydryl group?
Name the four levels of organization of proteins.
What are Primary; Secondary; Tertiary & Quaternary?
Name four components of membranes.
What are phospholipids, proteins, glycoproteins and cholesterol?
What conditions exist if a cell is in a hypotonic solution?
What is the concentration of solutes outside the cell are lower than the concentration of solutes inside the cell?
Why must experiments be randomized?
What is to eliminate bias?
What is a suspension?
What governs the activity or activity level of molecules involved with any biochemical process?
What is shape?
Differentiate between Active, Facilitated and Passive transport in regards to membranes.
Active transport requires the use of ATP to complete the transport process (e.g. the application of energy); Facilitated transport is special case of Passive transport which involves proteins in the process increasing the liklihood or rate of transport but does not require energy and Passive transport requires no energy and covers both facilitated and non-facilitated transport.
In which osmotic condition is osmosis said not to occur: Hypertonic, Isotonic or Hypotonic?
What is isotonic?
What value for each treatment is given by scientists as the correct answer for an experiment?
What is the mean?
What is the force or phenomenon that draws water up into a narrow tube?
What is capillarity or capillary action?
Name the monomers of each of the four major classes of biochemical molecules in the cell.
What are monosaccharides for carbohydrates; amino acids for proteins; glycerol; fatty acids or ring structures for lipids; and nucleotides for nucleic acids?
Name four of the six functions of proteins on membranes.
You can remember these six functions using the mnemonic JET RAT: Junctions, Enzymes, Transport, Recognition, Anchorage, and Transduction. [1]
Which osmotic condition leads to plasmolosis: Hypertonic, Isotonic or Hypotonic?
What is hypertonic?
