1. Homeostasis
Home/o = same stasis = stable
2. Hypothesis
a tentative explanation for an observation
the body’s internal clock
4. Mean
add all #;s and divide by the total count of #’s
5. Median
middle number
6. Mode
most frequent number
7. Range
The difference between the highest and lowest. (subtract the 2)
8. Standard Deviation
• 1. Find the mean
• 2. Subtract mean from every #
• 3. Square the mean from every #
• 4. Add all #’s together
• 5. Divide by one less than the total #
• 6. Obtain the square root
9. Accuracy
Accuracy is how close a measured value is to the actual (true) value.
10. Precision
Precision is how close the measured values are to each other. Repeatability
11. BMI
mass(kg)/(height(m))2
12. What is the function of Biruet Reagent?
Used to detect protein.  The more protein the deeper the blue.
13. Optical Density
ability to absorb light
14. Dependent Variable
• measured to determine if the manipulation of the independent variable had any effect.
• Plot on the y-value
15. Independent Variable
a factor that is manipulated in an experiment

Plot on the x-value
16. Diffusion
movement of particles from high to low until equilibrium is reached
17. Factors that effect diffusion:
• 1. Particle size
• 2. Temperature
• 3. Size of concentration gradient
• 4. Barriers and semipermeable
• 5. MembraneViscosity of liquid
18. Permeable Solute
can cross the membrane
19. Impermeable solutes
cannot cross the membrane
20. Dialysis
diffusion of solutes across a semipermeable membrane
21. Osmosis
diffusion of water across a semipermeable membrane
22. Tonicity
a measure of the osmotic pressure gradient (as defined by the water potential of the two solutions) of two solutions separated by a semipermeable membrane
23. Hypotonic
• 1. lower concentration of solutes outside the  cell
• 2. water moves into the cell
• 3. hemolyse
24. Isotonic
• 1. Equilibrium
• 2. No movement
25. Hypertonic
• 1. Higher concentration of solutes outside the
•     cell
• 2. Water moves out of the cell
• 3. Crenate

26. Which way will water flow across a membrane?
High to low concentration
27. Enzymes
biological catalysts
28. 3 types of Digestive Enzymes
• Lipase : for Lipids
• Amylase : for Carbs
• Pepsin : for protein
29. Substrate
substance that enzymes reacts and modifies to form a new product.
30. Iodine test
detect starch prestances
31. Benedict’s test
test for maltose
32. Biurets
test for protein
33. What is the purpose of Bile Salts
help digest fatty food by emulsifying the fat
34. Emulsification
the breakdown of large fat globules into smaller, uniformly distributed particles. It is accomplished mainly by bile acids in the small intestine
35. What is ELISA
Check for enzyme-linked antibodies or Antibody Titer
36. Sequence of steps in an ELISA

A.S.E.A.B.S  (ate sea biscuts)
• 1. Antigen
• 2. Wash
• 3. Serum
• 4. Wash
• 6. Wash
• 7. Substrate
37. Epitope
specific site of an antigen that causes the production of an antibody
38. Antibody titer
a measurement of how much antibody an organism has produced that recognizes a particular epitope
39. What is the purpose of the enzyme linked ANTIBODY
So it can bind to the antiogen
40. Western blot
used to detect specific proteins in the given sample of tissue
41. Spatial
increase in overall strength of a contraction that increases motor units
42. Concentration Time
the time the muscle contracts
43. Relaxation
the time the muscle relaxes
44. Temporal summation
increased rate of stimulus
45. Latent Period
the time that the muscle sits after stimulis occurred
46. Motor unit
a single motor neuron plus all the muscle fibers to which it connects.
47. Tentanization
The steady state of contractions when muscle stimulation is at a higher frequency.
