Study Notes

Key Biological Concepts

  • Paul Oliver is the biologist known for discovering the Pinocchio frog in New Guinea.
  • Biology is the scientific study of life and living organisms.
  • A species is defined as a unique type of organism that can interbreed within its group.

Fundamental Units and Structures

  • Atoms are the fundamental building blocks of all substances.
  • Molecules are formed by two or more atoms bonded together.
  • Molecules of life include lipids, proteins, RNA, DNA, and complex carbohydrates.
  • The cell is the smallest unit with emergent properties, vital to biological functions.

Biological Organization

  • Emergent properties refer to characteristics of a system not found in its individual components.
  • Tissues are specific cell types organized in a particular pattern, enabling complex functions.
  • An organ is a collection of tissues working together to perform a specific task.
  • Organ systems consist of sets of interacting organs that coordinate processes.
  • An organism is a living being made up of one or more cells.

Population and Ecosystems

  • A population comprises interbreeding individuals of the same species within a defined area.
  • Ecosystems consist of communities interacting with their surrounding environment.
  • The biosphere encompasses all regions of Earth where organisms exist.

Energy and Nutrients

  • Producers acquire energy and nutrients from their environment to produce their own food.
  • Nutrients are substances required for growth and survival that organisms cannot synthesize independently.
  • Consumers cannot produce their own food and obtain energy by feeding on other organisms.

Genetics and Biodiversity

  • Inheritance is the transfer of DNA from parents to offspring, influencing traits.
  • Biodiversity encompasses the variation among living organisms and ecological communities.
  • Bacteria and archaea are single-celled organisms characterized by DNA not contained within a nucleus.
  • Eukaryotes possess DNA enclosed within a nucleus and include diverse organisms like plants and animals.

Classification and Taxonomy

  • Taxonomy is the system used for naming and classifying species into hierarchical categories.
  • Traits refer to inherited characteristics that are common within a species.
  • A taxon is a rank or group of organisms that share specific traits.

Scientific Principles and Methodology

  • Scientific methods involve formulating a hypothesis, testing it, collecting data, drawing conclusions, and reporting findings.
  • Independent variables are defined and manipulated by the experimenter, while dependent variables are influenced by changes in the independent variable.
  • An experimental group consists of individuals receiving a treatment, while a control group is identical except for the independent variable.
  • A scientific theory is a well-supported hypothesis that has persisted through extensive testing and can be disproven by conflicting evidence.
  • Laws of nature describe phenomena consistently observed without fail, although the scientific explanation may remain incomplete.

Science vs. Pseudoscience

  • Science focuses on testable ideas pertaining to observable aspects of the natural world.
  • Pseudoscience includes claims or methods that resemble science but do not adhere to scientific standards of accuracy, objectivity, and reproducibility.
