Questions and Answers

What is a characteristic of a phase in a sample?

  • The composition is constant throughout (correct)
  • The properties are different from the other parts of the sample

    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

    • 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
