Festival and events - Essay Example In addition, we have also approached for additional funding from the Virgin Australia Airlines Pty Ltd that offers sponsorship based on their internal evaluations for events that deliver community benefits that align to the direction of the company (n.d). In this note, the company agreed to donate $1000 to sponsor the night trivia. Further, we were keen in controlling the costs of organizing the event by ensuring that we select a venue that is cost effective. Our choice of venue for the event is Apple cross Anglican Church where it is possible to reduce the total cost for holding the event while still making the guests to have fun. The main hall areas in the Apple cross Anglican Church can host a maximum of about 230 guests at a cost of $20 per hour after 6pm for non-profit events (Applecross Anglican Church, n.d). In addition, the venue has other additional offers such as tables and soft drinks. Further, we have approached the Sound Guys Company where we have obtained discounted sound system at a cost of $70 for the event. All these additional resources make the cost of holding the event in the venue to be within our limited budget. In order to attract a large number of guests, we have organized some prizes and gifts that will be given to the participants of night trivia. For instance, we have approached Dymocks book shop who agreed to donate different types of books in order to support the event. In addition, we have also approached Coles Supermarkets who agreed to support the night trivia by donating food hampers that will play great part in attracting more participants. Further, we were able to get some gifts such as soaps, perfumes and lotions from Elizabeth Shop that will also constitute the prizes to be given out. In order for the participants to win the gifts, the trivia will be organized in such a way that groups in a table will compete

The importance of Hydrogen Bonding in Biology Essay

The importance of Hydrogen Bonding in Biology - Essay Example The atom that covalently links to the hydrogen is the hydrogen bond donor and the other atom represent the hydrogen bond acceptor. These atoms have lone pair of electrons and a negative partial charge that enable them form this bond with hydrogen. Orphardt explains that hydrogen carries a partial positive charge. The formation of a hydrogen bond requires that hydrogen get attracted to an atom that has a partial negative charge. Orphardt explains that hydrogen bond is a directional bond this means the strength of a hydrogen bond relies on its alignment with two electronegative atoms (Orphardt, 2003). Hydrogen Bonding in Water Hydrogen bond is important in that it determines the physical and chemical properties of polar substances for example water. Water has a simple molecular structure consisting of two hydrogen atoms and the atom of oxygen. The hydrogen atoms covalently bond with the oxygen atom. The oxygen atom contains two lone pairs of electrons. The partial positive charge prese nt on the hydrogen atom together with the partial negative charge present on the oxygen atom gives water its polar characteristic. This attractive force between the oxygen atom and the hydrogen atoms result in the formation of a hydrogen bond. The polarity of water makes it a good solvent it allows polar substances and ions to dissolve in water. The polarity in water allows high cohesive force to exist in water molecules. One water molecule can form a hydrogen bond with other four water molecules. The high cohesion between water molecules allows water to be drawn up the xylem vessels in plants Hydrogen bonds bind water molecules together constantly form and break; therefore, changing the temperature of water requires the constant addition or removal of heat. This makes water have a high specific heat capacity water and favourable in preventing temperature changes in the body. The hydrogen bonds in water are responsible for the high surface tension in water. The hydrogen bonds hold w ater molecules tightly at the surface. This allows dense substances to float in water and for insects to walk on water Hydrogen Bonding in DNA Structure The hydrogen bonds determine and stabilize the structure of macromolecules such as proteins, nucleic acids. The hydrogen bond is responsible for holding together the three-dimensional structures of proteins and DNA. Hydrogen bonds are responsible for formation of biological structures such as double helix DNA strand. The hydrogen bond plays a critical role in ensuring the DNA structure is stable. Hydrogen bonding in a DNA structure is the chemical interaction responsible for base pairing. Arnold states that hydrogen bond holds together the double helix structure. The base pairs in DNA and RNA strands are connected by hydrogen bonds. The DNA molecule consists of four bases cytosine, guanine, thymine, and adenine. The DNA double helix structure has two polynucleotide strands that are intertwined together. The DNA structure is very sta ble because of DNA base pairs arrangement, which allows the interaction of the bases (Arnold, 2009). Hydrogen bonding is significant in holding together the polynucleotide strands of DNA. An adenine on one-strand pairs with a thymine base on the other strand and a guanine pairs with cytosine. Arnold describes that the stability of a double helix DNA strand is due to the internal and external hydrogen bonds existing between the complementary nucleotide base pairs. Arnold
