Both conform to the basic laws of chemistry and physics.

The basic unit of life, found in all living organisms.

Include lipids, proteins, nucleic acids, and carbohydrates.

Prokaryotic cells lack a membrane-bound nucleus, while eukaryotic cells have one.

The three domains are Bacteria, Archaea, and Eukarya.

Prokaryotic and eukaryotic cells both have a plasma membrane.

Present in the nucleus of eukaryotic cells; carries genetic information.

No devices or additional materials; must be taken in one sitting at UPL.

Experiments designed to determine differences between groups under controlled conditions.

The variable being measured in an experiment, which depends on other variables.

A testable statement predicting an outcome, often if-then in nature.

The simplest unit of biological organization that can exhibit all life properties.

The group in an experiment that does not receive the treatment, used for comparison.

A series of steps used for scientific inquiry, typically including observation, hypothesis, experimentation, and conclusion.

A test where fish health was monitored under different oxygen levels to see the effects on survival.

A statement that forecasts an expected outcome in an experiment based on a hypothesis.

A subatomic particle with no charge located in the nucleus of an atom.

A positively charged subatomic particle found in the nucleus of an atom.

A negatively charged subatomic particle that orbits the nucleus of an atom.

An atom that has the same number of protons and electrons is neutral.

Atoms that have lost electrons, gaining a net positive charge.

Atoms of the same element with different numbers of neutrons but the same number of protons.

A bond formed when two atoms share one or more pairs of electrons.

A bond formed when one atom transfers electrons to another, resulting in attraction between charged ions.

A standard for comparison in an experiment, often a group without the independent variable.

Elements like water, oxygen, nitrogen, and carbon are essential to all living organisms.

Molecules that contain carbon and are found in all living organisms.

The number of protons in the nucleus of an atom, unique to each element.

The particle in an atom with the smallest mass is the electron.

An experiment where only one variable is changed to ensure valid results.

Organisms are named using genus and species names, like Homo sapiens.

The flow of genetic information is DNA → RNA → Protein.

Arrangement of life complexity: Cell, Tissue, Organ, Organism, Population, Community, Biosphere.

A protective barrier that all cells possess along with DNA as genetic material.

A diagram showing evolutionary relationships and the order of species divergence.

A systematic process for answering questions through observation and experimentation.

Phylogenetic trees help understand the history and relationships between organisms.
