Study Notes

Introduction to Biology

Red pandas (Ailurus fulgens) are well-adapted to mountainous forests in Asia.
Their red and white coat provides camouflage in their environment.
Their long, bushy tail helps with balance in trees and provides warmth.
A bony projection in their wrist helps them grasp bamboo.
Red pandas are classified in their own family.

Biology: the Scientific Study of Life

Biology is the scientific study of life.
Properties of life include order, reproduction, growth, development, energy processing, regulation, response to the environment, and evolutionary adaptation.
The cell is the fundamental structural and functional unit of life.

Characteristics of Life

DNA is present in all living things.
Order refers to the structured arrangement of organisms.
Growth and development are essential for maturation.
Organisms maintain homeostasis (regulation).
Change or adapt to their environment.
Composed of cells (prokaryotes and eukaryotes), the simplest unit of life.
Obtain energy and convert it for use. (Include autotrophs and heterotrophs)
Reproduce to continue the species (sexual and asexual).
Respond to stimuli from the environment.

Domains of Life

Biologists categorize organisms into three domains (Bacteria, Archaea, and Eukarya).
Domain Bacteria: Prokaryotic; peptidoglycan cell walls present; further categorized as Eubacteria.
Domain Archaea: Prokaryotic; no peptidoglycan cell walls; further categorized as Archaebacteria (extremophiles).
Domain Eukarya: Eukaryotic; diverse groups of organisms; Protista, Fungi, Plantae, and Animalia).

Kingdoms of Life

Domain Eukarya contains four kingdoms;
- Protista: often unicellular with diverse characteristics; either plant-like (algae), animal-like (protozoa), or fungus-like.
Fungi: either unicellular or multicellular; have chitin cell walls; decomposers.
Plantae: multicellular; cellulose cell walls; autotrophs.
Animalia: multicellular, no cell wall; heterotrophs.

Levels of Biological Organization

Biologists study life across a diverse scale from molecular level to global level.
Molecules->cells->tissues->organ->organ system->organism->population->community->ecosystem->biosphere
Emergent properties result from interactions between parts.

Science and its Process

Science is a way of knowing about the natural world.
Science uses an evidence-based inquiry process.
A scientific theory is broad in scope and supported by strong evidence.
A scientific method employs observations, question formulation, research, hypothesis development, experimentation, data analysis, and reporting to explore questions.
Inductive reasoning draws broad conclusions from specific observations. (e.g., Sun always rises in the East).
Deductive reasoning derives specific conclusions from broad generalizations. (e.g., all organisms are made of cells; humans are organisms; therefore, humans are made of cells).

Controlled Experiments

In experimental studies, one factor is manipulated (independent variable) to see how that affects another variable (dependent variable).
In a controlled experiment, an experimental group is compared with a control group
An example would be a study on camouflage by comparing how a noncamouflaged and camouflaged mouse is affected by being in a light habitat vs. dark one.

Evolutionary Theory

Darwin proposed the theory of evolution by natural selection.
Evolutionary theory describes how inherited traits can vary, leading to different reproductive success rates and adaptations in populations.
Life has evolved from its earliest forms to the vast array of organisms existing today.

Systems Biology

Studying interactions among components of a biological system, is called systems biology.
Systems biology attempts to model complex systems and predict how their components will respond in specific circumstances
