The ability of an organism to maintain a stable internal environment, despite changes in the external environment.

The process by which organisms inherit traits from their parents and pass them on to their offspring.

The ability of an organism to change over long periods of time, adapting to its environment.

The process by which organisms take in and use energy from their surroundings.

The process by which organisms produce offspring.

The basic unit of life, which contains all the necessary components for life.

A molecule that stores genetic information and is passed down from parents to offspring.

The ability of an organism to react to changes in its environment.

The factor being manipulated or changed by the researcher in an experiment.

The factor being measured or observed in an experiment, and its response is dependent on the independent variable.

A group in an experiment that does not receive the treatment or manipulation being studied.

A group in an experiment that receives the treatment or manipulation being studied.

In the context of the experiment, the different levels of exposure to Geomyces destructans (the fungus causing WNS)

Whether or not the bats in each group developed white-nose syndrome (WNS).

A possible explanation for a phenomenon that can be tested through scientific experimentation.

Personal biases can influence how scientists interpret data. Scientists must remain objective.

A scientific study that investigates a possible cause-and-effect relationship between two or more aspects of the natural world through controlled experiments, manipulating variables to observe their impact.

A scientific study that observes and analyzes natural occurrences or patterns without manipulating variables. It's like watching a movie and taking notes, but without changing the plot.

A relationship where changes in one aspect consistently lead to changes in another, suggesting a possible cause-and-effect connection. Think of rainfall and plant growth.

A relationship where one aspect directly causes a change in another. Think of turning on a light switch and the light turning on.

A scientific approach that uses a systematic process of observation, experimentation, and analysis to answer questions about the natural world.

Questions or topics that cannot be investigated through empirical observation and experimentation. Think of moral or ethical dilemmas.

The process of experts in a field reviewing research before it is accepted and published.

A well-substantiated explanation that is supported by a vast body of evidence and has been repeatedly tested and confirmed.

A statement or fact that is objectively true and universally accepted based on repeated observations and experiments. They are not open to debate and are considered to be factual. For example, the human heart pumps blood throughout the body.

A set of procedures designed to test a hypothesis and gather objective evidence. This can involve conducting experiments, making observations, or collecting data.

A possible explanation for a phenomenon or observation that has not yet been systematically tested or supported by evidence.

A specific group of symptoms or signs that characterize a particular disease or condition.

Objective information or data gathered through observation, measurement, or experimentation. It's what you see, hear, measure, or experience.

The basic building block of life, commonly formed from components found in Earth's atmosphere.

A strong chemical bond formed when two atoms share electrons.

A type of bond involving the sharing of electrons between two atoms.

A bond formed between oppositely charged atoms due to the transfer of electrons.

A weak bond formed between a hydrogen atom and a highly electronegative atom, like oxygen.

The central element present in organic molecules, forming the backbone of life.

A chemical bond formed between amino acids, linking them together to form proteins.

The ability of organisms to maintain a stable internal environment despite external changes.

A substance that repels water, causing it to form beads and roll off surfaces.

A scale that measures the concentration of hydrogen ions (H+) in a solution, indicating its acidity or alkalinity.

The building blocks of proteins, made up of a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain (R-group).

The first amino acid in the sequence of any protein during protein synthesis.

Complex molecules composed of one or more long chains of amino acids, folded into specific three-dimensional shapes.

Specialized proteins that bind to specific antigens (foreign substances), triggering an immune response.

The universal solvent in living systems, participating in many chemical reactions and transporting substances.
