Lab Report #1 Ahmad Dweik Question/Problem Which phase of cell division / mitosis is seen most often in whitefish blastula? Introduction Cell division is the process of a parent cell dividing into two daughter cells. Mitosis is a type of cell division. In mitosis a parent cells chromosomes are copied and separated into two cells with different nucleuses but same DNA. There are steps or phases that take place that make the cell divide. The first phase is called Interphase. In interphase there

Materials The proponent has a direct contact with the onion farmers that will supply the raw materials needed. Machines There is no machine available here in the country for faster drying. Methods There are available methods for dehydrating/ drying onions. Manpower There is no need to hire professional workers

temperature has risen about 1.4 degrees F (0.8 C) since 1880‚ according to the new analysis. Exact rankings for individual years are sensitive to data inputs and analysis methods. "Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change‚" GISS climatologist Gavin Schmidt said. "While one year or one season can be affected by random weather events‚ this analysis shows the necessity for continued‚ long-term monitoring." Scientists emphasize that

and mitosis are both types of cell division. Cell division is the reproduction of cells‚ and requires the duplication of chromosomes. Mitosis takes place when the nucleus divides. Meiosis is a type of cell division that produces haploid gametes in diploid organisms. Mitosis and meiosis are two very different processes. While meiosis only requires the cell to divide twice‚ the cell only divides once during mitosis. This causes meiosis to produce four cells and mitosis to produce two cells. Mitosis

Comparing Mitosis and Meiosis Observe: 1. Organisms have a number of chromosomes in each of their body or somatic cells that is unique for that organism. This is called their diploid or 2n number. 2. Cells go through a cell cycle‚ whereby‚ much of the cycle does not include division‚ but at the end of this interphase in their cycle‚ they go through mitosis. 3. Cells replicate their DNA in the S phase of the cell cycle. 4. In the process of mitosis‚ cells replicate their DNA in the nucleus‚ form

AND REPLICATION WITHIN MITOSIS AND MEIOSIS ABSTRACT The processes of mitosis and meiosis were examined along with their frequency as well as each of the different steps and their time duration. It was found that the interphase stage of both mitosis and meiosis was the longest of all the stages as this was where most of the ‘action’ was happening such as cell growth and duplication of all cell organelles and chromosome replication also. It was also found that mitosis and meiosis have similar

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

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 is that each chromosome consists of chromatin. Once replicated‚ a chromosome consists

USE OF ONION ROOT TIPS FOR MITOTIC DIVISION OBSERVATIONS Introduction The zone of cell division on the onion root tip is a great place to observe mitotic cell divisions. Through the observation and comparison of different regions of the root tip‚ the duration of mitotic stages and mitotic indexes are determined for the various divisions of the root tip. Methods Each group used a compound microscope to analyze the different sections of the onion root tip. The root tip was visually
