Fleas are very small insects. They are all flightless and do not have eyes‚ although two ocelli may be present. Their antennaes are short and their mouthparts are adapted for piercing and sucking. The female flea lays a few eggs daily that total up to 300 to 400 in its lifetime. The eggs are laid usually on animals and most drop off where they spend most of their time. Bedding‚ floor crevices‚ carpeting‚ along baseboards and areas near their favorite sleeping and napping sites are especially likely

Identification of Unknown # 15 Abstract. One of the most fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The
