Habituation of Exploratory Behavior in Rats Regarding Spatial Rearrangement of Familiar Objects This experiment investigated the possibility of renewed exploratory behavior under the influence of spatial rearrangement‚ specifically after periods of habituation. Rats are very inclined to explore all aspects of novel environments that they are freshly exposed to‚ but eventually habituation

Preparation u Alcohols when heated in presence of H2SO4‚ H3PO4‚ P2O5‚ Al2O3 or BF3 undergo loss of water molecule with the formation of alkene. Conc. H2SO4 180oC H3PO4/P2O5 200oC Al2O3/BF3 350oC CH3-CH=CH2 + H2O CH3-CH2-CH2-OH CH3-CH=CH2 + H2O CH3-CH=CH2 + H2O u u Mechanism: In the first step OH group of the alcohol is protonated in a fast reversible reaction. Unlike OH group‚ protonated OH group is a good leaving group. Step 1: CH3 CH3-C-CH3 + H+ HO CH3 CH3-C-CH3 H2O+

1. What is ethics? Ethics is the branch of philosophy that involves systematizing‚ defending‚ and recommending concepts of right and wrong conduct. As a branch of philosophy‚ ethics investigates the questions “What is the best way for people to live?” and “What actions are right or wrong in particular circumstances?” In practice‚ ethics seeks to resolve questions of human morality‚ by defining concepts such as good and evil‚ right and wrong‚ virtue and vice‚ justice and crime. 2. What is administration

reaction serves as the starting material in the subsequent reaction. The multistep synthesis of benzilic acid begins with a conversion benzaldehyde to benzoin through a condensation reaction. The benzoin then oxidizes into benzil‚ which undergoes rearrangement to give benzilic acid. Benzoin Synthesis * When two benzaldehyde molecules condense in the presence of thiamine‚ it leads to the formation of a molecule of benzoin. The thiamine behaves as a coenzyme catalyst. This step of the reaction involves

Contents Oncogene An oncogene is a kind of abnormal gene that predisposes cells to develop into cancers. Unlike normal genes‚ which can be turned off after being turned on‚ oncogenes are altered in a way that keeps them stuck in a state of constant activity. That uninterrupted action helps drive the uncontrolled growth that underlies tumors. Oncogenes can be turned on by inherited changes - ones that are passed down from parent to child - or by cancer-promoting agents that

pairs from prophase of meiosis-1 split and migrate to opposite poles and then into separate gametes. Also‚ this splitting of chromosomes occurred apart from the splitting of the other chromosomes in that cell. 4. Recombination involves the rearrangement of genes by random chromosome assortment and crossing over with occurs during meiosis. Mutations‚ however‚ are unprecedented changes in genes which gives rise to entirely new forms of the gene and may occur in any type of cell. 5. Random chromosome

Mechanism 4 shows the debromination of 2α-bromocholestan-3-one to give 4. This mechanism which is similar to a Favoskii rearrangement‚ is likely to go via this path as other research has shown that there is often a by-product with this reaction. The by-product is cholest-4-en-3-one which requires the intermediate seen in the third molecule in the above mechanism. The intermediate is highly strained and with the presence of base a proton will be extracted which aids the collapse of the three membered

Running head: Research Paper: HOLOGRAMS 1 Yasmine Briedj Adelphi University What do flying cars‚ time machines and holograms all have in common? They’re future technologies that the world never thought they would see brought to life. This was until holograms were created. When talking about holograms‚ the first thing that usually comes to mind is their use in the entertainment industry for things like 3D movies and recreating musical artists. But‚ holograms actually have more uses
