Introduction: The question investigated in this lab was which drugs have the greatest and least affect on the pulse of the Lumbriculus variegates. Ethanol will cause the worms to become inactive‚ caffeine will cause the worms to become overactive‚ and nicotine will cause the worms to become more active. Lumbriculus variegatus is also known as black worm. This small species of worms currently lives in North America and Europe within marshes and ponds. They survive by eating microorganisms and organic

Food Packaging Food packaging draws on disciplines like chemistry‚ microbiology‚ food science and engineering. About 25% of the ex-factory cost is for packaging and thus provides the challenge for food packaging technologists to design and develop functional packages at low cost. Today packaging is pervasive and essential. It surrounds‚ enhances and protects the goods from processing and manufacturing through handing and storage to final consumption without packing‚ materials would be messy

This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you would have taken your first sample from. I will return to the lab with the samples of soil I have extracted from the site. Here I will make a solution from the samples in order to carry out the identification tests.

Laboratory safety is an integral part of any lab experience. If the participants are unkempt or precarious‚ they can easily cause a huge accident or even tragedy. When working in the lab‚ so many different hazards are faced. The rules of the laboratory are in place to ensure that one does not hurt themselves‚ let alone everyone else in the room or even the whole building. Each person needs to be responsible for themselves‚ while also watching for potential dangers others may not notice. The first
