Chapter 1. The science of biology  

. Science is a methodical approach to obtaining and examining data regarding the natural world.

. A deliberate, methodical practice of detecting and describing occurrences or processes is called observation.

. A hypothesis is a potential response to a scientific query or an explanation for a set of findings.

. Salt Marsh Experiment is a salt marsh was the subject of observations by scientists. They then employed scientific methods to respond to the inquiries raised by their observations.

. A controlled experiment is one where just one variable is altered.

. The control group in an experiment is the group that experiences the same circumstances as the experimental group, with the exception of one independent variable.

. Data, or information gleaned from observations, serves as proof.

. The steps of scientific process include observation and questioning, inference and hypothesis-building, controlled experiments, data collection and analysis, and conclusion-drawing.

. Science ideas can emerge in a variety of ways, from curiosity to the necessity to address a particular issue. Making observations, asking questions, speaking with other scientists, and reading about previous studies are common ways that scientists start a research.

. Science requires good communication skills. To ensure that the work complies with scientific norms, scientists review one another's work. One study's findings can inspire fresh thinking and additional research.

. A scientific theory is a thoroughly investigated explanation that permits scientists to make accurate predictions while accounting for a large number of observations and hypotheses.

. A well-tested theory combines a wide range of data and hypotheses, allowing scientists to make precise predictions about brand-new circumstances.

. Bias is an individual preference or viewpoint that is not based on facts or evidence.

. The scientific study of life is called biology.

. DNA is the genetic material that is passed down from parents to organisms.

. A signal to which an organism responds is known as a stimulus.

. The relatively stable internal physical and chemical conditions that organisms maintain are known as homeostasis.

. The series of chemical processes by which an organism accumulates or degrades components is known as metabolism.

. The biosphere, which encompasses land, sea, and the atmosphere, is the area of the planet where life is present.

. The cellular basis of life, information and heredity, matter and energy, growth, development, and reproduction, homeostasis, evolution, shape and function, unity and diversity of life, interdependence in nature, and science as a method of knowing are the big ideas in biology.

. Many overlapping fields in biology work together to investigate life at all scales, from molecules to the entire planet, using a variety of methods.

. When conducting experiments and collecting data, the majority of scientists use the metric system.
