Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

the experiment to test this question is coffee‚ Coke‚ tea. Some people have more stained teeth then others‚ and that is affected by their diets. Different liquids can to different things to your teeth‚ and the most frequent thing done to teeth is staining. The reason for this project is to test what different liquids stain the teeth the most‚ so that people can prevent their teeth standing by not drinking as much of certain liquids. The next most common type of tooth stain is from a persons

"TURMERIC: HOMEMADE WHITENING TOOTHPASTE" CHAPTER I Abstract: We are only recently becoming more aware of all the benefits of turmeric to our bodies. In addition to health benefits‚ turmeric also seems to have beauty benefits. Not only is it great for the skin‚ it also seems to whiten teeth! It is very skeptical‚ but the root plant we once thought to be only dyes to textiles can somewhat really make the teeth whiter and brighter! It sounds a little counter-intuitive to apply a rich yellow substance

important key in understanding plant biology‚ aiding this study are the fundamentals of histology and techniques in histochemistry. This experiment involved exercising free-hand sectioning techniques‚ learning maceration procedures and application of staining techniques. Sudan dye for Lipids and IKI test for starch were applied on section stem‚ root and leaf parts of Tridax procumbens. Stem cross-section of T. procumbens showed distinct ground tissues and fourteen to sixteen vascular bundles organized

layers of mineralised matrix. These lamellae are pink in colour which shows the eosin dye of H&E is staining this structure. This means that the lamellae of the osteons are acidophilic structures. The last structure of the osteon that can be seen in this figure is the cement line. This is a thin line that surrounds the entire osteon. It is purple in colour which shows the haemotoxylin dye of H&E is staining the cement line. This is turn means that this part of the osteon is a basophilic

EMG 9 and EMG 26 contain strain _lac-_(I- Z+ Y+) and strain _lac -_ (I+ Z- Y-)respectively.Three genes huddled together on the chromosome are required for two strains of _E.coli_ to utilize lactose.Consisting of three genes‚ namely‚ _lacZ_‚ _lacY_ and _lacA_‚ the _lac_ operon orderly handles these genes to code specific enzymes necessary for the metabolism of lactose. The genes _lacZ_‚ _lacY_ and _lacI_ would code for beta-galactosidase‚ galactosidase permease
