Scientific method
A testable explanation for an observation
What is a hypothesis?
The scientific study of life.
What is biology?
The ability to maintain stable internal conditions.
What is homeostasis?
A group of organisms of the same species living in one area
What is a population?
This type of reasoning moves from specific observations to general conclusions.
What is inductive reasoning?
The first step of the scientific method
What is an observation?
The smallest unit of life.
What is a cell?
The ability to produce offspring.
What is reproduction?
All populations living together in one area
What is a community?
This type of reasoning moves from a general principle to a specific prediction.
What is deductive reasoning?
A factor that can change during an experiment.
What is a variable?
The earliest life forms on Earth according to scientists.
What are prokaryotes?
Using energy to carry out life processes.
What is energy processing (metabolism)?
Living things plus their nonliving environment.
What is an ecosystem?
Scientific work is evaluated by experts through this process before publication.
What is peer review?
This group does not receive the experimental treatment.
What is the control group?
Organisms with cells that contain a nucleus.
What are eukaryotes?
Changes in populations over time that help organisms fit their environment.
What is evolution?
The highest level of biological organization.
What is the biosphere?
Science that expands knowledge without an immediate practical application.
What is basic science?
This what science should be.
What is logical, ethical, repeatable, objective?
Organisms that lack a nucleus and membrane-bound organelles.
What are prokaryotes?
Name three characteristics shared by all living things.
What are homeostasis, reproduction, growth and development, response to stimuli, order, energy processing, adaptation, or evolution? (Any three)
Put these in order from simplest to most complex: organ, tissue, cell, organ system.
What is cell → tissue → organ → organ system?
Carl Woese proposed these three domains of life.
What are Bacteria, Archaea, and Eukarya?
