- - - - In Observing Minute Specimens used microorganism to be observed using a microscope.
    - - Sterile Technique is used in transferring growing organisms from pure culture to a sterile medium without unwanted contaminants using a sterile medium.
    - - Culturing of Bacteria attempts to identify the bacteria in a clinical sample cannot be done unless isolated colonies are used.
    - - Cytochemical Methods are used to locate specific chemical constituents within the cells by differentiating a particular part from the others by colouring them with a specific stain or dye.
    - - Autoradiography ia a technique is used for study the steps and location of synthesis of molecules and to trace metabolic events in the cells.
    - - In Paper Chromatography, chemical substances present in a mixture can be separated according to their molecular weight, size, and solubility in the solvent that rise up to different heights of the Whatman Filter paper.
    - - Cell Fractionation ia a method in which different organelles of the cell that having different size and weight are separated by a centrifuge at different speeds.
    - - Ultracentrifugation is a technique by a rotation at a high speed, particles or organelles of different sizes and shapes are separated according to its density.
    - - Tissue Culture technique involves growing of living cells outside the organism by providing necessary needs and condition to survive.
- - - - Drying is a process which involves an adequate length of time and exposure o "dry air" to preserve specimens.
    - - Weighing is used to determine how heavy is the object using weighing scales.
    - - Grinding is a process of breaking down particles into a smaller form.
    - - Centrifugation is a process in which centrifugal force is exerted to separate substances or particles according to its density.
    - - Distillation is a process which separates liquid substances that involves heat.
    - - Filtration is a process in which solid particles are separated in a liquid or gaseous substances using a filter medium.
    - - Chromatography is an analytical technique commonly used in separating mixture of chemical substances into its individual components.
    - - pH measurements used pH value to determine the amount of hydrogen ions contained in a solution to know whether it is acid or base
