Students are eager to follow because they have a shared interest in learning about facts that they may never read in their biology book. For example‚ one of my favorite topics in the mitotic conspiracy is what happens in interphase. I make the analogy that interphase is like being in a village where living is more communal. I specifically have the students to compare and contrast modern day family structure to those of traditional West African heritage. I tell them in kinship clans you cannot

Sarah Haynes Dr. Christerson Honors Biology 9D 11 April 2015 10.1 Assessment 1a. Identify two reasons why a cell’s growth is limited. The larger a cell becomes‚ the more demands the cell places on its DNA. In addition‚ a large cell is less efficient in moving nutrients and waste material across the membrane. 1b. As a cell’s size increases‚ what happens to the ration of its surface area to its volume? As a cells size increases‚ the volume increases more than the surface area. However‚ the ratio

chromosomes is 46‚ which are paired into groups of two making 23 pairs of chromosomes. The process of meiosis is broken down into two courses: meiosis I and meiosis II. Before the stage of meiosis‚ a cell must undergo a phase described as interphase. Interphase consists of three stages known as the G1 phase‚ S phase‚ and the G2. The G1 phase is the phase in which the cell develops and grows. The S phase is the stage that represents the synthesis of DNA replication. The G2 phase of the cycle is the

Name the three phases of interphase and describe an activity unique to each phase. 3 phases of Interphase: * G1 – the centrioles begin replicating * S – DNA is replicated * G2 – final preparations for mitosis are completed and
