Part 2: Effects of Environment on Mitosis. Experimental Hypothesis: If we put onion root tips in IAA solution then the rate of Mitosis will increase. Null Hypothesis: There will be no difference Part 1- Post Lab Question If a cell contains a set of duplicated chromosomes‚ does it contain any more genetic information than the cell before the chromosomes were duplicated? No‚ because if it is duplicated‚ it would have the same number of chromosomes unless there was a

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 not broken apart yet to begin forming a new cell.3 2. Prophase: In

AP LAB # 3: MITOSIS AND MEIOSIS Website to go for quizzes and activities: Print out the quizzes for mitosis and meiosis http://www.phschool.com/science/biology_place/labbench/ OVERVIEW Exercise 3A is a study of mitosis. You will simulate the stages of mitosis by using chromosome models.You will use prepared slides of onion root tips to study plant mitosis and to calculate the relative duration of the phases of mitosis in the meristem of root tissue. Prepared slides of the whitefish blastula

Shawn Lab 8 Title: Mitosis and Meiosis Exercise 1: Mitosis in Animal and Plant Cells Questions: A.) What is the purpose of mitosis? The purpose of mitosis is to create or produce more cells for a living organism. Mitosis occurs when genetic substance in the nucleus divides or separates in order to create more cells. Cytokinesis normally occurs next and the single cell develops into two separate cells. This same process continues to occur over and over creating more cells for an organism replacing

Cell Multiplication 1. Why do bone injuries generally heal‚ while injuries to the spinal cord and brain do not? Bone tissues can regenerate fairly easy; in the area where the bone has been fractured‚ the bone will work to produce new cells and small blood vessels that will rebuild the bone. The new cells will cover the ends of each broken piece of bone until the gap between the bones has been closed and the bone has been repaired. However‚ like the brain‚ the spinal cord is part of the central

Ryan Juergens 01/29/2013 Pd:05th Mitosis VS. Meiosis All living things are made of cells from bacteria to the most complex being on earth us. These cells must reproduce in some way one method is mitosis that would take place in bacteria while‚ another way is meiosis one that you may have heard of in sex education. These‚ two processes may seem similar at first but as you take a closer look like we do in this essay you will learn that these processes are very different in many distinctive

Description of Floating Buoy Light Introduction The floating buoy lights below was first manufactured during the time period of the BP oil spill in April 2010. The company Champion Safety produced an estimated 5500 buoys to protect the oil catching lines in the Gulf of Mexico from getting run over by any passing boats or ships. The floating buoy lights are solar powered with a bright white‚ amber or multicolored LED lights along with the corrugated hoses that can be seen up to three or more

1. Describe what is happening during DNA replication. Make sure you include which proteins are involved and what they are doing during replication. DNA replication is semi-conservative. It occurs in “origin of replication” to form DNA ligase. In order for DNA to replicate it needs to follow a couple of steps. First: The parental strand divides in 2 separate strands; the helicase unwinds by cutting hydrogen bonds. Then‚ each strand is a template that attracts and binds complementary nucleotides
