Home/o = same stasis = stable
a tentative explanation for an observation
the body’s internal clock
add all #;s and divide by the total count of #’s
most frequent number
The difference between the highest and lowest. (subtract the 2)
- 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
Accuracy is how close a measured value is to the actual (true) value.
Precision is how close the measured values are to each other. Repeatability
What is the function of Biruet Reagent?
Used to detect protein. The more protein the deeper the blue.
ability to absorb light
- measured to determine if the manipulation of the independent variable had any effect.
- Plot on the y-value
a factor that is manipulated in an experiment
Plot on the x-value
movement of particles from high to low until equilibrium is reached
Factors that effect diffusion:
- 1. Particle size
- 2. Temperature
- 3. Size of concentration gradient
- 4. Barriers and semipermeable
- 5. MembraneViscosity of liquid
can cross the membrane
cannot cross the membrane
diffusion of solutes across a semipermeable membrane
diffusion of water across a semipermeable membrane
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
- 1. lower concentration of solutes outside the cell
- 2. water moves into the cell
- 3. hemolyse
- 1. Equilibrium
- 2. No movement
- 1. Higher concentration of solutes outside the
- 2. Water moves out of the cell
- 3. Crenate
Which way will water flow across a membrane?
High to low concentration
3 types of Digestive Enzymes
- Lipase : for Lipids
- Amylase : for Carbs
- Pepsin : for protein
substance that enzymes reacts and modifies to form a new product.
detect starch prestances
test for maltose
What is the purpose of Bile Salts
help digest fatty food by emulsifying the fat
the breakdown of large fat globules into smaller, uniformly distributed particles. It is accomplished mainly by bile acids in the small intestine
What is ELISA
Check for enzyme-linked antibodies or Antibody Titer
Sequence of steps in an ELISA
A.S.E.A.B.S (ate sea biscuts)
- 1. Antigen
- 2. Wash
- 3. Serum
- 4. Wash
- 5. Enzyme linked antibody
- 6. Wash
- 7. Substrate
specific site of an antigen that causes the production of an antibody
a measurement of how much antibody an organism has produced that recognizes a particular epitope
What is the purpose of the enzyme linked ANTIBODY
So it can bind to the antiogen
used to detect specific proteins in the given sample of tissue
increase in overall strength of a contraction that increases motor units
the time the muscle contracts
the time the muscle relaxes
increased rate of stimulus
the time that the muscle sits after stimulis occurred
a single motor neuron plus all the muscle fibers to which it connects.
The steady state of contractions when muscle stimulation is at a higher frequency.
