New cards
Desirable Difficulty
When material becomes difficult, which causes you to learn better.
2
New cards
Retrieval
the process of recovering or locating information stored in memory
3
New cards
Metacognition
understanding one’s thought process
4
New cards
Active Studying
studying that ensures long time memory by using strategies beyond simply reading the material
5
New cards
Passive Studying
Not actively taking notes or studying, most info is lost after this.
6
New cards
Synapse
a junction between two neurons, or a neuron and a target. It permits the transmission of electrical or chemical signals. The synapse is formed between presynaptic and postsynaptic neurons
7
New cards
Scanning Objective
Lowest Power
8
New cards
Low Power
The second smallest power
9
New cards
High power
The highest power
10
New cards
Total magnification
Objective power x objective power (10)
11
New cards
Base
Keeps the microscope in one piece
12
New cards
Stage
Holds slide
13
New cards
diaphragm
Controls the amount of light
14
New cards
Light source
Source of light. Mirror or light.
15
New cards
eyepiece (ocular lens)
Magnifies the image produced
16
New cards
Arm
Supports and connects parts of the microscope
17
New cards
Nosepiece
Hold's all the lens and attaches them to microscope
18
New cards
Coarse Adjustment
Moves the stage up and down
19
New cards
Fine Adjustment
Carefully focus the microscope
20
New cards
empirical
Based on an experiment and observation rather than theory
21
New cards
inquiry
a search for knowledge
22
New cards
Eukaryotic Cells
Clearly defined nucleus, and organelles like mitochondria and chloroplasts
23
New cards
Prokaryotic cells
Cells that lack a nucleus and other complex organelles
24
New cards
Archaea
A group of microorganisms that lack a nucleus, all of them are prokaryotic.
25
New cards
Bacteria
prokaryotic, unicellular, and has no organelles or organized nucleus
26
New cards
Eukarya
A group of organisms whose cells all have a nucleus. All animals, plants, fungi, and some unicellular organisms are in this domain.
27
New cards
antibiotic
Substance that kills bacteria
28
New cards
probiotic
Live microorganisms that have health benefits
29
New cards
Fermentation
The process of breaking down sugar with enzymes in microorganisms like yeast
30
New cards
3 domains of life
Archaea, Bacteria, and Eukarya
31
New cards
Endosymbiont Hypothesis
That eukaryotic cells evolved from prokaryotic cells
32
New cards
ATP
Stores energy and becomes adp after using energy
33
New cards
ADP
A molecule created when you use ATP
34
New cards
photosynthesis
When plants turn water and CO2 into glucose and oxygen to create energy.
35
New cards
Cellular Respiration
The process of cells using glucose and oxygen to make CO2, water and ATP
36
New cards
Mitochondria
The organelle that helps with cellular respiration
37
New cards
Chlorplasts
The organelle that helps with photosynthesis
38
New cards
Cellular Respiration Formula
C6H12O6 + 6O2 > 6CO2 + 6H2O
39
New cards
Photosynthesis equation
6CO2 + 6H2O > C6H12O6 + 6O2
40
New cards
glucose
A sugar that allows plants and other organisms to store energy
41
New cards
empirical
derived from experiment and observation rather than theory
42
New cards
data
Models, charts, graphs, statistics
43
New cards
independent variable
The manipulated variable that doesn't depend on the other for change
44
New cards
dependent variable
Depends on the independent variable for change
45
New cards
Controls
Variables that aren't changed
46
New cards
Technology
Tools that are used to help us draw a conclusion
47
New cards
osmosis
Water moving from a place of high concentration to low concentration.
48
New cards
anaerobic respiration
Process of breaking down sugars to make energy without oxygen
