Chapter 1- Intro to Biology

Properties of Life

Energy Processing, Growth and Development, Response to Environment, Reproduction, Regulation, and Evolutionary Adaptation

Emergent Property

A property which a complex system has, but the individual members do not have

DNA

Deoxyribonucleic Acid

RNA

Ribonucleic Acid

Gene Expression

Process of converting information from gene to cellular product (Often Proteins/Enzymes)

Producers

Organisms that generate their own chemical energy

Consumers

Organisms that feed on other organisms or their remains

Evolution

The process of change that has transformed life on earth over billions of years

Inquiry

Search for information and explanations for natural phenomenon

Independent Variable

Value is not affected by another variable (Typically variable being manipulated/changed)

Dependent Variable

Variable’s whose values depends on the value of another variable (Typically the variable being measured/ result of change)

Quantitative Data

Express as numeral measurement, organized into tubes and graphs

Ex: Number of mice caught

Qualitative Data

Often take the form of recorded description

Ex: Light vs dark coat/ Full moon vs no moon

Controlled Experiment

An experiment in which all factors are held constant expect for one

Ex: One pot of beans gets water while the other does not

Genus

To which a species belongs

Species

More unique to that species

Ecosystem

An organism’s interactions with each other and their physical environment

Positive Feedback

An end product speeds up its own production

Negative Feedback

Response reduces the initial stimulus
