Question: How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root

Life Science Lab. A. Arnold Tuesdays @ 2:30 September 30th‚ 2011 Lab Report: Nuclear and Cell Division. PART A: Stages of Mitosis in my own words. 1. Interphase: DNA has formed already‚ but it remains in the simple form of chromatin. Chromatins are structures that are loosely coiled in the cell.3 I also observed during my lab that this was the only stage where I could still see a nucleus and nucleolus intact within the cell; this is because it’s the only stage where the nuclear membrane has

Mitosis: (onion roots) Root cells are good for observing mitosis; this is because they’re in the tip of the root which is an area of the plant that grows quickly. This results in more cells going through mitosis all at once‚ also allowing us to examine the different stages of mitosis. Stages: 1. Interphase: DNA replicates‚ but has not formed the condensed structure. They remain as loosely coiled chromatin. The nucleus is still intact. 2. Prophase: The DNA molecules progressively shorten

and why. In addition many victims may desire to meet and confront the offender to get some closure or justice. In some cases this is made possible via restorative justice process. This process is all about bringing the victim and the offender together. Restorative justice process: Restorative justice process is a process where the victim of a crime and the criminal are brought together to share their thoughts and feeling. The purpose of this is to help each side understand the pain that was

helix. (Gyrase) 2. Explain the relationship between chromatin‚ chromosome‚ chromatid‚ and centromere. Chromatin: DNA + Protein. DNA and associated proteins in the nucleus. Chromosome: Genetic material of cell (genome). It is made out of chromatin. Chromatid: Half of a duplicated chromosome. One of two identical attached copies of a replicated chromosome. Centromere: A small region of a chromosome where sister chromatids attach to each other. Important for mitosis and meiosis. The relationship

October 22‚ 2012 Sexually Transmitted Diseases A sexually transmitted disease (STD) is an infection that you can get from having sex with another person who has an infection. There are several types of sexually transmitted diseases that affect men and women every year. In Chapter 9 of our textbook‚ the topic of sexually transmitted diseases was discussed. This is a rising issue amongst young adults in this generation. “One in four new sexually transmitted diseases (STDs) infections occur

They hold an extreme double standard by expecting women to be supportive listeners when they aren’t. The second process is ritual. The example in our lecture and book for ritual is a wedding ceremony. This ritual gives the impression that women are subordinate to men. This is communicated

M2 - Explain the way that data transmitted over a network can be protected by encryption. Below‚ I will explain the way that data transmitted over a network can be encrypted to provide protection. I will explain what encryption entails‚ how data is transmitted‚ and why it is important to encrypt private data to ensure its protection. What Does Encryption Entail and How Does It Work? Encryption entails rearranging data in such a way that only the owner of both the encryption and decryption
