Lab

Lab Introduction Water plays a vital role in biological systems. Some species are able to survive in diverse environment such as fishes in salt water, Cactus plants in dry land and mammalian cells in aqueous surrounding because of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation, we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab, we will determine the effects of hypertonic, isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell's placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal cell's placed in hypotonic solution, it begins to swell and then finally lyse; a plant cell placed in this type of solution however, is said to be turgid. In isotonic solution, the animal cell stays the same (normal) whereas the plant cell becomes flaccid.en: Epidermi s cells of Rhoeo Discolor; the vacuole...

3 Cases of Erroneous Punctuation with Quotations

3 Cases of Erroneous Punctuation with Quotations 3 Cases of Erroneous Punctuation with Quotations 3 Cases of Erroneous Punctuation with Quotations By Mark Nichol In each of the following sentences, punctuation associated with a quoted phrase or a partial or full quotation is not appropriate. Discussion after each example explains why the punctuation should either be changed or omitted altogether, and one or more revisions illustrate correct treatment of the quoted material. 1. The old saying, â€Å"What gets rewarded gets done,† is as true with risk management as with any other business process. The phrase â€Å"the old saying† should not be treated restrictively- â€Å"What gets rewarded gets done† is not the only old saying; it is being described as an old saying- so omit punctuation between the phrase and the saying itself: â€Å"The old saying ‘What gets rewarded gets done’ is as true with risk management as with any other business process.† 2. The company responded in a statement Friday that the newspaper article showed, â€Å"a complete disregard for basic journalistic standards.† Because the partial quotation complements the attribution to complete a sentence that requires no internal punctuation, do not use such punctuation to separate the attribution and the quotation: â€Å"The company responded in a statement Friday that the newspaper article showed ‘a complete disregard for basic journalistic standards.’† 3. â€Å"I would like to do a college fund for him, it’s not the kid’s fault,† he said. Regardless of whether such a sentence is a quotation or not, the use of a mere comma to separate two independence clauses without the support of a conjunction is incorrect: â€Å"’I would like to do a college fund for him; it’s not the kid’s fault,’ he said.† However, using a semicolon in a quotation has always seemed stiffly formal to me; simply as a personal preference, I would use a more dashing punctuation mark: â€Å"’I would like to do a college fund for him- it’s not the kid’s fault,’ he said.† Another alternative is to insert the attribution between the two clauses, treating them as separate sentences: â€Å"‘I would like to do a college fund for him,’ he said. ‘It’s not the kid’s fault.’† Want to improve your English in five minutes a day?
