Biology Review Quiz Notes

Vocabulary flashcards covering the nature of science, scientific method, laboratory calculations, and characteristics of life based on lecture review notes.

Science

A process, an organized way of observing and asking questions about the natural world.

Goals of Science

To provide natural and testable explanations for events in the natural world, use explanations supported by data to understand patterns in nature, and make useful predictions about natural events.

Scientific Method

A methodology involving observing, asking questions, making inferences, forming hypothesis, conducting controlled experiments, collecting and analyzing data, and drawing conclusions.

Formal Hypothesis

An "if….then….because" statement structured as: If (independent)….then (dependent)…. because (inductive and deductive reasoning).

Controlled Experiment

An experiment designed around an independent variable, a dependent variable, and a control group.

Data Analysis

The interpretation of scientific data through graphing.

Peer Review

Publishing articles in scientific journals that allows researchers to share ideas and allows other scientists to evaluate work and test the data, ensuring science is transparent and shared.

Scientific Attitudes

Core attitudes of scientific inquiry: curiosity, skepticism, open-mindedness, and creativity.

Bias, Ethics, and Moral Values

Considerations where applying scientific information involves understanding the role of science context in society and its limitations.

Density

$D = \frac{M}{V}$, where volume ($V$) can also be found using Water Displacement.

Calculating Percent of Error

$$\frac{\text{Experimental} - \text{Accepted}}{\text{Accepted}} \times 100\%$$

Characteristics of Life

Cells, Reproduce DNA, Growth and Development, Energy, Respond to Stimuli, Homeostasis, Evolve and Adapt.

Levels of Structure

Cells, tissue, organs, organs systems, organism.

“Xenobots: ethical and moral concerns vs advantages of further development and capabilities”

Xenobots are programmable living cells derived from frog embryos, raising ethical concerns about their use and impact on ecosystems, while offering advantages in biotechnology, medicine, and environmental cleanup.

Scientific Notation

A mathematical notation for expressing numbers as a product of a coefficient and a power of 10, allowing for convenient representation of very large or very small values.

Scientific theories vs Scientific Laws

Scientific theories explain phenomena based on extensive evidence and observations, while scientific laws describe consistent relationships or patterns observed in nature that are universally accepted.

Asexual vs Sexual Reproduction.  Advantages/Disadvantages

Asexual reproduction is faster and needs one parent but has little genetic variation, while sexual reproduction usually needs two parents and more time but creates genetic variation.
