Bacterial Morphology MLT1 Task 11- Lab 2 Johnny Archuleta Western Governors University Question A and C answers. A wet mount stain is when a drop of water is placed onto the microscope slide. The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged

Mitosis and meiosis are the means by which reproduction takes place. Mitosis creates an exact duplicate of cell so that old cells can be replaced‚ such as in skin‚ hair‚ and bones. Meiosis allows a cell to unite one half of its genetic makeup with a cell from another partner to create an entirely new organism. Mitosis Mitosis is the process by which two daughter cells are formed‚ each containing a complete set of chromosomes. Mitosis is the process by which an organism creates new cells‚ such

Activity Background Information Meiosis is the process by which eukaryotic organisms produce egg and sperm having half the genetic information (haploid) of the other cells in the organism’s body (diploid). You will notice some similarities to mitosis but some definite differences in meiosis that result in genetic diversity in the gametes as well as the offspring formed by the eventual fusion of the egg and sperm. Two of the most noted differences in meiosis are that 1) there are two complete

division of nuclear material in which each new nucleus obtains the same number of chromosomes and the same nuclear code as the original nucleus is call mitosis. Mitosis occurs in four phases. Interphase occurs between mitosis. Interphase: Cell contains easily seen nucleus and nucleolus- chromosomes appear as fine dots within nucleus Mitosis: 4 steps Prophase – cell nucleus enlarged –nucleolus no longer visible- chromosomes appear as short strands within nucleus. Metaphase – chromosomes

Alana Rogers Date of experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble

It is important that cells go through mitosis because it makes each new cell contain the same gentic information. If meiosis did not occur the reproduction would cease to exist. Mitosis is the process of chromosomes dividing. There are four steps that it goes through. Between cell division the cells are in interphase. During this there is cell growth and the genetic material such as DNA is contained in the chromosomes‚ duplicated so that when the cell divides each new cell has a full version of

Mitosis v. Meiosis Biology is the study of life and the processes that a life form undergoes. Two very important biological processes in the field of biology are mitosis and meiosis. These two biological processes comprise the majority of what is studied in every cell unit within biology class. Many students have a difficult time understanding the similarities and differences between the two. Students also struggle to understand the phases of each cell division and the reason they occur.

1 and Mitosis are very similar events‚ however‚ they have certain differences. One difference is crossing over. Meiosis 1 does cross over and because of that‚ it creates genetic changes. Mitosis ‚ on the other hand‚ does not cross over. Something else that is different is the way it occurs. Meiosis 1 is sexual but Mitosis is asexual. Another change is the number of divisions that each event goes through. Meiosis 1 goes through 2 divisions which ends up having 4 haploid cells‚ however Mitosis only
