Major groups of lipids
|
Saturated, unsaturated, steroids, phospholipids, and wax.
|
|
Major groups of carbohydrates
|
Starch, Glycogen, Cellulose, and Chitin.
|
|
Saturated vs unsaturated lipids
|
Saturated fat has no double bonds between carbon atoms. mono-unsaturated fat has one double bond between carbon atoms. Polyunsaturated has two or more double bonds between carbon atoms.
|
|
Solute
|
The substance being dissolved by a solvent to form a solution.
|
|
Hypotonic
|
A solution that has low concentration of solutes compared to that of the solution placed adjacent to it. Syrup in water.
|
|
Hypertonic
|
A solution that has a high concentration of solutes relative to an adjacent solution. Water in syrup.
|
|
Scientific Method Steps
|
Make an observation, ask a question, hypothesis, experiment/test hypothesis, analy
|
|
Hypothesis
|
A hypothesis is a
proposed explanation or answer to your question based on an educated/ informed guess. |
|
Diffusion
|
n is the movement of molecules from a region of
higher concentration to a region of lower concentration |
|
Control
|
controls are set up the exact same as your experimental test, but with only one thing different
|
|
Test for monosaccharides (glucose) and disaccharides (lactos
|
Benedict's reagent. Positive results rage from yellow to orange to red depending of concentration.
|
|
Test for polysaccharides (starch)
|
Lugol’s solution or Iodine-Potassium Iodide (IKI). Turns dark blue or black in presence of starch.
|
|
Osmosis
|
; water molecules move down a concentration gradient across a
membrane |
|
Test for lipids
|
Sudan red forms a separate red layer in the presence of lipids. Negative turn solution pink.
|
|
Test for proteins
|
Biuret reagent. Changes form blue to violet in the presence of proteins.
|
|
Storing microscope
|
1. Rotate the 4X objective into place.
2. Remove the slide from the stage. 3. Slide the light intensity lever to 0. 4. Turn off the power. 5. Unplug the cord and wrap it around the base of the microscope. 6. Replace the dust cover. 7. Use two hands, one under the base, to return the microscope to the cabine |
|
Calculating magnification
|
Total magnification = Power of objective lens (4X, 10X, 40X) x Power of ocular lens (usually
10X |
|
Muscular system
|
Movement
|
|
PCR, or Polymerase Chain Reaction
|
A method that creates billions of copies of a specific DNA section can be made from a single fragment, thus vastly increasing the quantity of DNA material
available to be analyzed |
|
Digestive system
|
Functions as a path for eaten food to travel and be absorbed by the organism
|
|
Respiratory system
|
Facilitates breathing functions
|
|
Circulatory system
|
Facilitates blood movement throughout
the body |
|
Excretory system
|
Filters the blood and removes
contaminants or excesses from the body |
|
Reproductive system
|
Determines male or female; functions to produce offspring.
|
|
Skeletal system
|
Physical support for movement
|
|
Nervous system
|
Communication and control over body functions.
|
|
Stained gram negative bacteria
|
pink. Gram negative has a phospholipid outer wall.
|
|
Stained gram positive
|
purple. Gram positive has an outer carbohydrate cell wall.
|
|
Dna extraction
|
Lysis, purification, precipitation. lysis-heat, Purification-detergent. precipitation-alcohol dehydration of DNA.
