Assignment 1 (1) Name two properties of water that result from the polar bonding between its molecules. (2 points) Cohesion and Surface tension are the two properties of water that result from the polar bonding between its molecules. 1. Cohesion: The likelihood of same kind of molecules to stick together is known as Cohesion. Compare to most of other liquids, Cohesion is way stronger for water. Hydrogen bonds between similar molecules makes water Cohesive. 2. Surface tension: Surface tension means how hard it is to stretch or break the surface of the liquid. Because of the polar bonding water consist high surface tension. (2) Examine table 3.2 on page 39 of your textbook (The table 3.2 may be on a different page in the eBook depending on your settings). From this figure list three elements and show the molecular formula for of 3 specific compounds. (3 points) Elements shown in table 3.2: 1. Oxygen 2. Hydrogen 3. Carbon Molecular formula for compounds: 1. Ethanol- C 2 H 6 O 2. Acetic Acid- C 2 H 4 O 2 / CH 3 COOH 3. Methylamine- CH 5 N / CH 3 NH 2 4. Oxetane- C 3 H 6 O (3) Figure 4.18A in the textbook shows the structure of cilia on the surface of a cell. What cellular organelle would you expect to be found in this cell near the energy requiring cilia? What will the cilia be using for energy? (2 points) After seeing figure 4.18A in the textbook which shows the structure of cilia on the surface of a cell, Mitochondria organelle is found in this cell near the energy requiring cilia. Mitochondria is also known as powerhouse of the cell which produces ATP. Cilia use ATP for energy which is produced by mitochondria.
