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
This quiz covers the concepts of mixtures and phases, including the composition and properties of each phase. It also discusses the difference between pure substances and mixtures.
