State clearly what the experiment is about. 2. Observation & Background Information Highlight what you have observed in reality and from research which directly reflects the topic and the hypothesis you are seeking to form. 3. Hypothesis Formulate a scientific prediction/explanation based on the observation. The Hypothesis should be clearly stated for testing. This should be no less than three (3) paragraphs expressing what you have observed happening to bread in your household over a period of time, and the conditions under which the fresh bread normally start changing. In addition, include information you would have researched on the internet on the types of mold, which type actually grows on bread, what conditions increases the growth of that mold on bread, and the health risks of keeping mouldy bread in the home as well as consuming it. Highlight the independent/changeable factors/conditions associated with the experiment. (Example: Moisture, Dark/Light) 8. Responding Variable Highlight whatever factors of the experiment which will respond to change. (Example: One bread will grow mould faster than one) 9. Expected Results Your expected results are typically expressed in a very structured table, listing, short paragraph, or graph in which you wish to use for the execution of the experiment. These structures are used for describing what you expect your results will be. 10. Inferences Your inferences are a list of three (3) to five (5) sentences which specifies your support or rejection of the hypothesis, and logical reasons why. 11. Observation(s) Highlight what you have observed throughout the entire experiment. Represent your observations with images/drawings of the experiment set up (before and after your execution of the experiment), detailed paragraph(s), and/or data table.

Methods: Blood and urine samples were collected before and up to 24 hours after administration of ASA in 22 healthy volunteers. Pharmacokinetic parameters and measurements of platelet aggregation were determined using validated techniques. Results: A comparison between administration routes showed that the geometric mean dosecorrected peak concentrations (C max /D) and the geometric mean dose-corrected area under the curve (AUC 0-∞ /D) were higher following intravenous administration of ASA 500 mg compared with oral administration (estimated ratios were 11.23 and 2.03, respectively). Complete inhibition of platelet aggregation was achieved within 5 minutes with both intravenous ASA doses, reflecting a rapid onset of inhibition that was not observed with oral dosing. At 5 minutes after administration, the mean reduction in arachidonic acid-induced thromboxane B 2 synthesis ex vivo was 99.3% with ASA 250 mg intravenously and 99.7% with ASA 500 mg intravenously. In exploratory analyses, thromboxane B 2 synthesis was significantly lower after intravenous versus oral ASA 500 mg (P,0.0001) at each observed time point up to the first hour after administration. Concentrations of 6-keto-prostaglandin 1α at 5 and 20 minutes after dosing were also significantly lower with ASA 500 mg intravenously than with ASA 500 mg orally. Conclusion: This study demonstrates that intravenous ASA provides more rapid and consistent platelet inhibition than oral ASA within the first hour after dosing.

Have we been given a choice in life, or is life being driven by a series of unalterably predetermined events? (L.I.T) As highlighted by (Lawson, 1994), the word fate is a multivalent term, and it comes from the Middle English adoption of the Latin word fatum meaning, 'that which has been spoken [by God]'. More so, fate, in its first meaning from the Oxford English Dictionary is explained as 'the principle, power and agency by which events are unalterably predetermined from eternity'. Correspondingly, the Oxford English Dictionary of the modern age defined fate as 'the development of events outside a person's control, regarded as predetermined by a supernatural power'. The concept of fate opposes the biblical idea of choice. Choice is the idea which suggests that human beings have all been given free will, and it is dependent solely on human beings to shape their own destiny. Vincenzo Crawford: I became skeptical to the concept of freewill after I sat in the silence of my dwelling, fraternizing my thoughts with the premises on which fate and freewill holds. In the midst of confusion, I pondered, how can you be given an ultimate choice when it isn't a guarantee that you will experience the desired outcome of your choice? For a person can do a good act and achieve not the expected product(s) of the good act done; instead, the result(s) of the act holds a potential of aiding the detriment of the doer.
