    Mitosis is easily observed in cells that are growing at a rapid pace such as whitefish blastula or onion root tips, which was used in this lab experiment. The root tips contain and area called the apical meristem that has the highest percentage of cells undergoing mitosis. The whitefish blastula is formed directly after the egg is fertilized. This is a period of rapid growth and numerous cellular divisions where mitosis can be observed. In mitosis the cell is in interphase, and have a distinct nucleus and nucleoli where the thin threads of chromatin thicken into distinct chromosomes and the nuclear evvelope breaks open releasing them into the cytoplasm. The firs signs of the spindle begin to appear, next the cell begins metaphase, where the spindle attaches to the Centromere of each chromosome and moves them to the same level in the middle of the cell. This level position is called the metaphase plate. Anaphase begins when the chromatids are separated and pulled to opposite poles, then the final stage is telophase. The nuclear envelope is reformed and the chromosomes gradually uncoil. Cytokinesis may occur, in which, a cleavage furrow will form and the two daughter cells will separate. Meiosis is more complex and involves two nuclear divisions. The…

    Meiosis is an important part of the life cycle that gives rise to the genetic variation in offsprings. Meiosis in fungi differs from those in plants and animals. Fungi are composed of hyphae, which are tubules that make up the frame. These hyphae together form a clump or a mat that is the mycelium (Campbell, 637). The hyphae are key to fungus reproduction. Typically fungi produce large amounts of spores through either sexual or asexual reproduction. Fungal hyphae are normally haploid. When two fungi mate, the hyphae fuse together. The movement of the two fungal nuclei into one cytoplasm is known as dikaryon. Next, the cells go into karyogamy. The two nuclei fuse and provide diploid cells. These newly produced cells then go through mitosis and meiosis that cultivate spores (Campbell, 639). The spores are called ascopores and are found in a saclike structure that is the ascus. The spores germinate and form hyphae (Campbell, 64)…

    The nucleic acid of a virus is protected by a protein coat called the capsid. The structure of the capsid is ultimately determined by the viral nucleic acid and accounts for most of the mass of a virus, especially of small ones. Each capsid is composed of protein subunits called capsomeres. In some viruses, the proteins composing the capsomeres are of a single type; in other viruses, several types of protein may be present. In some viruses, the capsid is covered by an envelope, which…

    A rare disease that is inherited is Tay-Sachs disease. What the disease does is it destroys nerve cells located in the Spinal cord and the brain. The most common type of Tay-Sachs appears in infants. The disease is present early in development but the symptoms usually don’t appear until after the age of 4. Symptoms appear as a slowing or halting of development to include loss of motor skills, seizures, vision and hearing loss. A red spot on the eye referred to as a cherry-red spot is usually found during an eye exam. There is no known cure for Tay-Sachs disease. Children with the disease usually die by age 5.…

    Response Feedback: Meiosis occurs only in replicating gametes or reproducing cells. In phase one, the number of chromosomes is reduced by half but the chromatid pairs remain together. In phase two, the chromatids split apart forming four daughter cells. Non-germ cells such as red blood cells or skin cells undergo mitosis.For more information on this topic, consult:Carol Mattson Porth and Glen Matfin, Pathophysiology, 8th Edition, page(s) 122-123, 123fCarol Mattson Porth, Essentials of Pathophysiology, 2nd Edition, page(s) 52-53, 53f Elizabeth J.

    In the column “The Ethicist” by Randy Cohen, he received a question from a reader. It demonstrated how parents are concerned about teachers exchanging donations, from students, for a grade. They believe that this action defeats the purpose and value of charities and donations. Students can easily set expectations for receiving a reward after achieving a considerate act. However this exchanging process is able to inspire students to take generous actions in their future. The exchange can give a student an opportunity to gain many benefits if they decide to participate. This is encouraging students to gain knowledge on life and on the academic experience. This trade allows students to become aware and acknowledge that there are organizations and charities to help out others.…
