Life starts out in organisms that are so small and complex even the naked eye can’t see. It starts from the zygote and ends up becoming the person you are today! It all starts from a cycle, when fertilization, the fusion of two haploid gametes, (the sperm and the egg) forms a diploid zygote. This is how the chromosome number in a life cycle changes from haploid to diploid (23 to 46). A lack of chromosomes or having more than 23 chromosomes can cause syndromes like Down Syndrome or Turner Syndrome, which will be discussed later. Mitosis is the division of a haploid or diploid cell into two duplicate daughter cells. Mitosis is basically the division of a nucleus into two duplicate cells, and both have the same number of chromosomes. These identical cells are called totipotent cells, which have the ability to develop into new organisms. A good example of cell division in haploid cells is how the male honey bee develops from an unfertilized haploid cell. For humans, each cell contains 50% DNA from mom and other 50% from dad. Since these cells are eukaryotic, they include both introns and exons. Exons are the nucleotide segments in genes and introns are non coding regions. In …show more content…

Mitosis and meiosis are similar in several ways and different in others. The similarities include that both processes involve IPMAT. IPMAT is interphase, prophase, metaphase, anaphase and telophase. The parent cells are diploid. They both end with cytokinesis. In Metaphase and Metaphase II, the sister chromatids line up along the center. Then in Anaphase and Anaphase II, these chromatids are split and pulled towards the centrosomes. The differences are that mitosis consists of 1 division while meiosis consists of 2. Four genetically different, haploid sex cells are the products of meiosis and 2 identical, diploid somatic cells from mitosis. Mitosis occurs in all organisms except viruses and meiosis only occurs in plants, animals, and fungi.
Once you have finished the video let’s practice by completing these problems (be sure to include units!):
Mitosis: This is the process by which a cell duplicates the chromosomes in its cell nucleus in order to generate two identical daughter nuclei.

Prejudices have been along as far as any of us can remember. From way back when slaves were first being taken from Africa in the 1600s, to the belief of women to only be worthy because they had children. Discrimination against those groups and several more have always been around. In the novel, To Kill a Mockingbird by Harper Lee, she discusses the racial and sexual prejudices of Maycomb County, through the words and experiences of Tom Robinson and Scout. The lessons Scout learns about how to deal with these issues and where they come from are applicable to all forms of prejudice all over the
Out of a total from 26 sequences only 6 were made up of 4‘s while 20 were composed of different structures of 2‘s. This tells us that 77% of the asci showed crossing over while 23% did not.
Walters has continued to conduct interviews with such well known personalities as Princess Diana of England, General Colin Powell, Hillary Rodham Clinton, wife of President William Clinton, Robert Shapiro, famous defense attorney, etc. Her ability in drawing people out, understanding the situation and to make it as clear as possible during interviews has attributed to her success. The year 1996 marks the twentieth anniversary of her relationship with the American Broadcasting. Her 20/20 television show is always in the weekly top ratings according to the polls. Walters has substituted many times for a vacationing Ted Koppel on his Nightline program and has her own special programs throughout the year.
Mitosis is the process of duplicating nuclear material one cell becomes two cells. A cell contains 46 chromosomes, this is known as diploid. This process involves prophase, metaphase, anaphase, and telophase. Mitosis ensures the continuation of the organism and helps the body build and repair. Meiosis on the other hand is for production of haploid cells, 23 chromosomes, that together with another human, new organisms are created.

The death penalty remains one of the most controversial topics in the study of criminal justice. Hundreds of convicted criminals have seen their fate by the hands of capital punishment in the course of United States history. Hundreds of others are still awaiting the day their sentence will be carried out. However, even though many of Americans still believe the principal role of capital punishment is deterring future crimes, thousands of others condemn the United States criminal justice system for its errors and fallacies, which result in erroneous capital punishment decisions and legalized violence against innocent people.
Compare and Contrast Mitosis and Meiosis Meiosis and mitosis describes the process by which cells divide, either by asexual or sexual reproduction to produce a new organism. Meiosis is a form of cell division that produces gametes in humans these are egg cells and sperms, each with reduced or halved number of chromosomes. The number of chromosomes is restored when two gametes fuse together to form a zygote. A cell with two copies of each chromosome is called diploid cell and a cell with one copy of each chromosome is called a haploid cell.
