4.I believe that our 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

double-helix looks like a ladder‚ twisted as if it was a spiral staircase. DNA Replication: Replication is an essential function of DNA. It must be able to replicate itself accurately so that as a cell divides‚ it will be able to pass its hereditary information and its genetic code to its daughter cells. Replication precisely copies DNA so that new molecules contain the same exact sequence of bases as the original strands. DNA replication occurs in the nucleus. It takes place during the S phase of

Unlike Basal Metabolic Rate (BMR) Body Mass Index (BMI) is determined by an individual’s height and body weight. It is widely used to determine whether the individual belongs to a healthy weight group. In simpler terms body mass index is the value that represents the weight status of human body in relation of the amount of fat present in it. Similar to Basal Metabolic Rate now it is also possible to easily calculate body mass index using BMI calculator for men and women. Similar to BMR calculator

THE ETHICAL USES OF CELL PHONES IN THE NURSING HOMES BY THE STAFF Abstract The morals and values combine to form ethics‚ technology and the changes it brings in today’s society‚ the effect of cell phones‚ the different use of the cell phone‚ and who can use their cell phones in the nursing homes. Ethics describes a system of morals that are studied‚ recommended‚ and accepted by society. These unwritten rules‚ made up of morals and

Lab Report 1: Subculturing Adherent Cells Fibronectin‚ integrin alpha 3‚ and actin are all involved in cellular adhesion at both the cellular and molecular levels. Integrins are the primary trans-membrane receptors that mediate dynamic interactions between the extracellular matrix and the actin cytoskeleton whenever a cell is motile. Integrins bind to the extracellular matrix and link to the actin cytoskeleton via a shirt cytoplasmic tail; they also help determine cellular binding specificity because

What Is a cooperative society ? A cooperative (also co-operative or co-op) is a business organization owned and operated by a group of individuals for their mutual benefit.[1] A cooperative is defined by the International Cooperative Alliance’s Statement on the Cooperative Identity as "an autonomous association of persons united voluntarily to meet their common economic‚ social‚ and cultural needs and aspirations through jointly owned and democratically controlled enterprise".[2] A cooperative may

Behavior of Gases and Absolute Zero Determination Lab Report Experiment 4 Introduction In this experiment we measured the relationship between temperature‚ volume‚ and pressure. Objectives: Conduct a set of experiments‚ each of which illustrates a gas law. Gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From your results‚ derive a single mathematical relationship that relates pressure‚ volume‚ and

potential difference in voltaic cell. Aim: To investigate the effect of concentration of electrolyte of the potential difference in voltaic cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction‚ two half-reactions occur; one reactant gives up electrons (undergoes oxidation) and another reactant gains electrons (undergoes reduction). Voltaic cell is a device in which a

Electrochemical Cells Lab Report AP Chemistry Block 1 Analysis: The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution
