Intro to Biology

Hypothesis

________:: proposed explanation based on limited evidence, starting point for further investigation.

Regulation

________:: how living systems are monitored, coordinated, developed, and maintained.

Null Hypothesis

________:: proposes that no statistical significant exists (reject or fail to reject after experiment)

Positive Feedback

________:: output increases the output, amplifies effects when something needs to happen quickly, helps return to homeostasis faster.

Negative Feedback

________:: output decreases the response and shuts down the pathway, maintains homeostasis.

Matter

________:: calls, fundamental unit of life, anything that occupies space and has mass.

Energy

________:: neither created nor destroyed, most systems lose ________ through heat, matter cycles through ________.

Evolution

________:: natural selection and adaptation over generations, fundamental theory of biology.

Communication & Interaction

________:: how living systems receive and exchange info, interactions between and within systems.

Control setup

________:: control group, doesnt receive independent variable, used for comparison to verify conclusions.

Qualitative Data

________:: cant be counted /measured, can be observed /recorded, qualities and characteristics.

Modal Organisms

________:: help scientists understand complex biological processes by observing systems of simple organisms (e.g.

Quantitative Data

________:: can be counted /measured in numerical values.

Evolution

natural selection and adaptation over generations, fundamental theory of biology

Matter

calls, fundamental unit of life, anything that occupies space and has mass

Energy

neither created nor destroyed, most systems lose energy through heat, matter cycles through energy

Information

central dogma DNA → RNA → proteins, DNA is lifes main info molecule, proteins control metabolic activities

Regulation

how living systems are monitored, coordinated, developed, and maintained

Communication & Interaction

how living systems receive and exchange info, interactions between and within systems

hypothesis

proposed explanation based on limited evidence, starting point for further investigation

control setup

control group, doesnt receive independent variable, used for comparison to verify conclusions

Controlled Variables

variables that remain constant/unchanged throughout experiment, same for all groups

Manipulated Variable

variables changed by researcher, independent variables, what is being tested

Dependent Variable

response to changing independent variable, what is being measured for effects of independent variable

Quantitative Data

can be counted/measured in numerical values

Qualitative Data

cant be counted/measured, can be observed/recorded, qualities and characteristics

Null Hypothesis

proposes that no statistical significant exists (reject or fail to reject after experiment)

Modal Organisms

help scientists understand complex biological processes by observing systems of simple organisms (e.g

Negative Feedback

output decreases the response and shuts down the pathway, maintains homeostasis

Positive Feedback

output increases the output, amplifies effects when something needs to happen quickly, helps return to homeostasis faster
