the science of biology

by ty carroll

Science

the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.

Observation

the action or process of observing something or someone carefully or in order to gain information.

Data

facts and statistics collected together for reference or analysis.

Inference

a conclusion reached on the basis of evidence and reasoning.

Hypothesis

a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

Spontaneous generation

the supposed production of living organisms from nonliving matter, as inferred from the apparent appearance of life in some supposedly sterile environments.

controlled experiment

is a scientific test that is directly manipulated by a scientist, in order to test a single variable at a time. The variable being tested is the independent variable, and is adjusted to see the effects on the system being studied.

manipulated experiment

A manipulated variable is the independent variable in an experiment.

theory

a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.

biology

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.

cell

the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.

asexual reproduction

Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only
