1

Desirable Difficulty

When material becomes difficult, which causes you to learn better.

New cards
2

Retrieval

the process of recovering or locating information stored in memory

New cards
3

Metacognition

understanding one’s thought process

New cards
4

Active Studying

studying that ensures long time memory by using strategies beyond simply reading the material

New cards
5

Passive Studying

Not actively taking notes or studying, most info is lost after this.

New cards
6

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

New cards
7

Scanning Objective

Lowest Power

New cards
8

Low Power

The second smallest power

New cards
9

High power

The highest power

New cards
10

Total magnification

Objective power x objective power (10)

New cards

Source of light. Mirror or light.

New cards
15

eyepiece (ocular lens)

Magnifies the image produced

New cards
16

Arm

Supports and connects parts of the microscope

New cards
17

Nosepiece

Hold's all the lens and attaches them to microscope

New cards
18

Coarse Adjustment

Moves the stage up and down

New cards
19

Fine Adjustment

Carefully focus the microscope

New cards
20

empirical

Based on an experiment and observation rather than theory

New cards
21

inquiry

a search for knowledge

New cards
22

Eukaryotic Cells

Clearly defined nucleus, and organelles like mitochondria and chloroplasts

New cards
23

Prokaryotic cells

Cells that lack a nucleus and other complex organelles

New cards
24

Archaea

A group of microorganisms that lack a nucleus, all of them are prokaryotic.

New cards
25

Bacteria

prokaryotic, unicellular, and has no organelles or organized nucleus

New cards
26

Eukarya

A group of organisms whose cells all have a nucleus. All animals, plants, fungi, and some unicellular organisms are in this domain.

New cards
27

antibiotic

Substance that kills bacteria

New cards
28

probiotic

Live microorganisms that have health benefits

New cards
29

Fermentation

The process of breaking down sugar with enzymes in microorganisms like yeast

New cards
30

3 domains of life

Archaea, Bacteria, and Eukarya

New cards
31

Endosymbiont Hypothesis

That eukaryotic cells evolved from prokaryotic cells

New cards
32

ATP

Stores energy and becomes adp after using energy

New cards
33

ADP

A molecule created when you use ATP

New cards
34

photosynthesis

When plants turn water and CO2 into glucose and oxygen to create energy.

New cards
35

Cellular Respiration

The process of cells using glucose and oxygen to make CO2, water and ATP

New cards
36

Mitochondria

The organelle that helps with cellular respiration

New cards
37

Chlorplasts

The organelle that helps with photosynthesis

New cards
38

Cellular Respiration Formula

New cards
40

glucose

A sugar that allows plants and other organisms to store energy

New cards
41

empirical

derived from experiment and observation rather than theory

New cards
42

data

Models, charts, graphs, statistics

New cards
43

independent variable

The manipulated variable that doesn't depend on the other for change

New cards
44

dependent variable

Depends on the independent variable for change

New cards
45
