observations are repressentative of cell division taking place in the oinon root tip. Firstly‚ this is because our numbers of the number of cells in each phase of mitosis are similar to the rest of the groups‚ so we can assume our results are most likely correct. We can also assume our calculations are right because we know that Interphase is the most active phase in the process of cell divison‚ which would agree with our calculations since we assume that approxiamtly 93% of cells are going though Interphase

Task 1 • Describe the structure of an enzyme as a protein‚ in terms of tertiary/ quaternary structures. 1) Primary Structure This is in reference to the order of way that amino acids are connected to form a protein. These are built up from 20 amino acids‚ and follow these structures o A carbon (the alpha carbon) bonded to the four groups below: o A hydrogen atom (H) o A Carboxyl group (-COOH) o An Amino group (-NH2) o A "variable" group or "R" group 2) Secondary Structure This is in reference

Purpose: Examine the role of the cell membrane in the cell by disrupting its function using temperature (Biology 107 Laboratory Manual 2014). This will improve the general understanding of optimal growing temperatures and the breakdown of the cell membrane Procedure: Betacyanin solution of a known concentration was diluted to create a dilution series‚ then placed in a spectrophotometer set to 525 nm. The absorbance of the dilution was used to create a standard curve for betacyanin. Discs of living

Courtney Cubine 6/19/13 June 20‚ 2013 Separation of a Mixture of Solids Purpose: The purpose of this experiment was to help the student learn how to separate a mixture of multiple different solids and determine the percentage of each component of the mixture. Procedure: I started off by removing the iron using the magnet‚ and then I weighed all of the iron I obtained from the mixture in a container I already knew the weight of and calculated the net weight of the iron.

Structure and function of macromolecules within a living organism ‘Some biological molecules in organisms are small and simple containing only one or a few functional groups‚ others are large‚ complex assemblies called macromolecules’ [1]. The term macromolecule is convenient because the bulk properties of a macromolecule differ from those of smaller molecules. These large chemical compounds have a high molecular weight consisting of a number of structural units linked together by covalent
