kinds of microscopes include; phase-contrast‚ dark-field‚ polarizing and UV. Each of these microscopes differs in the source and manner in which the light is passed through the specimen to be viewed. The microscopes that are usually used in biology labs are compound binocular or monocular light microscopes. Compound microscopes have a minimum of two magnifying lenses (ocular and objective). Binocular microscopes have two eyepieces while the monocular ones have one eyepiece. The ocular lens of a

Lesson 02.08 DBA/Module Exam Lesson 02.01: Chemistry of Life · Explain why biological macromolecules are important for everyday life. Cells make large macromolecules by bonding smaller molecules together into chains called polymers (from the Greek polys‚ "many‚" and meris‚ "part"). Polymers are large molecules composed of many identical or similar subunits called monomers. There are four categories of biological macromolecules that provide energy and structure to living organisms and their cells
