Q

Control

A

a trial run in the experiment that illustrastes “normal” conditions when the indepentant variable is not manipulated

24
Q

Constants

A

Factors in the experiment that does not change from trial to trail

25
All data mechanisms must have what 2 things
titles and untits
26
Qualitative Data
-descriptions in words -based on observation such as color, odor, or texture
27
Quantitive Data
-numeric measurements -Data is objective -mass, volume, temperature, disance, concentration, time, or frequency
28
Levels of organization in order
Atom, molecule, macromolecule, organelle, cells, tissue, organ, organ system, organism, population, community, ecosystem, biosphere
29
Objective
unbiased, not influenced by feelings, intrest, and prejudices
30
Subjective
biased, influenced by feelings intrest prejudices
31
What can influnece results (biases)
race, gender, politics, religon, nationaity, economic intrest
32
What is a bias
A predjudiced presentaion of material; a constant error in estamating a value
33
What are the 6 characteristics of ife
Reproduction, Growth/Development, Metabolism (use energy), maintain homostasis, Made up of cells, Respond to stimuli,
34
Reproduction
asexual or sexual, pass on DNA or RNA
35
Growth/Development
directed by DNA, stages of life
36
Homostasis
maintain s stable internal enviroment
37
Energy
Need it for metabolism
38
Respond to Stimuli
like moving hand if yuo touch something hot
39
Biodiversity
variety of life; increases from poles to equatior
40
Ocular or Eyepiece
Part of the microscope that you look through
41
Nosepiece
rotates to change objective
42
Stage
where specimen is placed for observation
43
Stage clips
hold slides in place
44
Diaphragm
controls the amount of light entering the fiel dof view
45
Coarse Adjustment Knob
used for focusing under low power
46
Fine Adjustment Knob
usdd for adjusting under high power
47
How to find total magnification
ocular X objective
48
Field of View
circular area you observe when looking into a microscope
49
What happens to the field of view as magnification increases?
It shrinks and you see more details
50
Reverse-Image
When observing specimens under a microscope the image you observe is a reversed image of how it looks on the slide
51
Resolution
the ability of a microscope is the ability to clearly determine the two seperate points or objects as singular distinguishing entities
52
Depth of Field
the tickness of the plane of focus
53
Large depth of field =
larger area focused
54
Small depth of field=
only part can be focused
55
Unit Conversions
