ionic‚ polar or covalent will dissolve in it‚ therefore more reactions take place while in solution with water. Often in organisms substances must be in solution and water is the solvent. Plants can only obtain mineral salts in solution and human digestion will only dissolve soluble foods‚ meaning large starch molecules must be broken down into soluble sugars. Also many organisms living in water spend most of their time underwater‚ yet they require oxygen to respire‚ and as water is such a good solvent

The unknown bacteria A and bacteria B have to be identified by its genus and species. First both bacteria had to be inoculated into a TSA agar media using the streak plate method. Four quadrants were drawn‚ so that the bacteria could be isolated as much as possible. Each bacteria was inoculated into two different plates‚ so that one could be incubated at 37 degrees Celsius and the other at 25 degrees Celsius. Bacteria B‚ which was incubated at room temperature showed red colonies throughout its media

relationship between two organisms where one organism benefits but the other is neutral‚ there is no harm or benefit. An example of commensalism is a flatworm attaching to the horsecrab and eating the crab’s food while the crab is not affected. Commensalism *Parasitism is a type of symbiotic relationship between organisms of different species

Unable to read the Gram Stain at first it was later confirmed that Unknown #7 was a gram negative bacteria. When introduced to Starch Unknown #7 produced no zone of clearing showing that it did not contain the enzyme amylase. When introduced to the Lipid Unknown #7 did produce a zone of clearing indicating that it did contain the enzyme lipase. When introduced to Casein Unknown #7 produced no zone of clearing indicating that it did not contain the enzyme protease. When streaked onto the Gelatin‚

Short Essay 2: Genetically Modified Organism Debate A genetically modified organism is used to refer an organism whose genetic material has been changed by genetic engineering techniques‚ which cut and combine DNA molecules from different organism into one molecule (Wikipedia‚ 2012). This way‚ scientists can give it new characteristics that people desire but do not have normally. Since the benefits brought by genetically modified organism are extremely obviously‚ such as lower

The Dangers of Genetically Modified Organisms In 1980‚ the first GMO patent was issued through a U.S. Supreme Court ruling. A mere thirty-five years later this fairly new discovery is readily available in an over-abundance to consumers for consumption. Genetically Modified Organisms have been developed because they do not follow the natural laws of crop production. They have been engineered for herbicide tolerance and rapid growth among other purposes. The Food and Drug Administration has stated

Amongst many problems that living organisms face‚ one of the biggest is the change in the temperature of the environment. Why is this a major problem for living organisms? A change in the temperature of the environment disrupts many of the body’s enzymes and regulatory proteins‚ changing their shape and perturbing their function. However‚ organisms have taken two different approaches to tackling this problem we call this organisms endotherms and ectotherms but in this essay‚ we will talk about an

The effect of mutations on living organisms Mutations occur when there is a change in the base sequence on the DNA strand. Most mutations have absolutely no effect due to them occurring in the introns‚ or the “junk DNA”. However some mutations occur on the exons‚ and these are the ones that can be potentially harmful to the organism‚ although in some exceptional cases random mutations can be beneficial‚ and pressured mutations are almost always beneficial to the survival of a species. Harmful
