Study Notes

Phases and Mixtures

A phase is any part of a sample that has a uniform composition and properties.
A heterogeneous mixture consists of two or more phases.
Oil and water are an example of a heterogeneous mixture, as they do not mix evenly and form separate layers, each of which is a phase.

Types of Mixtures

Examples of homogeneous mixtures: air, sugar water, rainwater
Examples of heterogeneous mixtures: oil and water, sand and water, kerosene and water

Soil Classification

Topsoil: no definition provided
Subsoil: no definition provided

Branches of Biology

Anatomy

The study of the structure of a plant or animal
Includes the study of cells, tissues, and organs and how they are organized in the body
Divided into several branches, including histology, embryology, gross anatomy, zootomy, phytotomy, human anatomy, and comparative anatomy

Biochemistry

The application of chemistry to the study of biological processes at the cellular and molecular level
Explores chemical processes related to living organisms
A laboratory-based science combining biology and chemistry

Botany

The study of plants, including their structure, properties, and biochemical processes
Includes plant classification and the study of plant diseases and interactions with the environment

Cytology

The examination of a single cell type, often used in fluid specimens
Used to diagnose or screen for cancer, fetal abnormalities, and infectious organisms

Embryology

The study of the formation and development of an embryo and fetus

Entomology

The scientific study of insects
Includes the study of genetics, taxonomy, morphology, physiology, behavior, and ecology of insects

Ecology

The study of the relationships between living organisms and their physical environment
Seeks to understand the interactions between living things and their habitats

Genetics

The study of how genes and traits are passed down from one generation to the next
Includes the study of molecular genetics, epigenetics, and population genetics

Herpetology

The study of amphibians and reptiles
Includes the study of morphology, behavior, ecology, and evolution of amphibians and reptiles

Ichthyology

The study of fish, including bony fish, cartilaginous fish, and jawless fish
Includes the biology, taxonomy, and conservation of fish, as well as husbandry and commercial fisheries

Molecular Biology

The study of the structure, function, and interactions of biological molecules, such as DNA, RNA, and proteins

Mitosis, Meiosis, and Cell Cycle

Mitosis: no definition provided
Meiosis: no definition provided
Cell Cycle: no definition provided

Physics and Chemistry

Physics: the branch of natural science that deals with the properties and interactions of matter and energy
Chemistry: the branch of natural science that deals with the composition, structure, properties, and change of matter

Geology and Astronomy

Geology: primarily studies the Earth's physical structure and substances
Astronomy: the study of the universe beyond Earth's atmosphere
