Mitosis

It is said that ‘’ Nature has invented reproduction as a mechanism for life to move forward. As a life force it passes right through us and makes us a link in the evolution’’. Reproduction is one of the essentials elements to live it is one of the characteristics of all living things; in fact, The process by which gametes are formed is the Gametogenesis which, is the combination of meiotic and mitotic divisions that happen to form gametes; although, spermatogenesis and oogenesis both do happen…

Introduction The common name of the Vulpes vulpes is the red fox. The red fox has a relatively long body with dense fur. The fur is typically a rusty red color and the legs are darker in color, sometimes even black. Foxes have black pointed ears and long canine teeth. On their underside, the fur is white from their nose down to their belly, orangish-red fur on its back, sides, and head. Red foxes have white fur under their neck and on their chest. A male fox, also called a “dog” weighs…

Cancer is a group of diseases which involves defects in the cellular control mechanism. The growth of multicellular organisms occurs due to the reproduction of cells. This happens as the existing cells divide by mitosis to form new cells which is a process that is regulated by some factors in our body. Sometimes, due to reasons such as spontaneous mutations, an irregular and uncontrollable cell growth occurs, forming malignant tumours. Besides, these cells have a characteristic of possessing an…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

me pass entrance test at Troy High School, where the Honor Biology class allotted during my ninth grade, and by maintaining a grade I was allowed to have AP Biology during my Junior Year. Biology lab enhanced my practical learning where I observed mitosis in developing embryonic cell of white fish, and plant cell both in Zea Mays Leaf (monocot) and Syringa leaf (eudicot). I keenly observed a dissected Pig's brain in the AP Biology lab, its anatomical structure influenced my passion.…

Docetaxel, also known as toxetere, is used as an anti- cancer chemotherapy drug. It is used to treat cases of breast, lung, prostate, head, and neck cancer. Docetaxel is administered through IV. The amount of docetaxel patients receive depends on a lot of factors. Factors such as height, weight, the type of cancer being treated, and how far along the cancer has developed factors into how much medicine the patients receive. Use of docetaxel can result in low white and red blood cell counts. This…

Erwin Schrödinger was a physicist pioneer who gave a series of lectures in 1944. They were published under the title What is Life? (Harold, 2001). Though philosophical in nature, many have wondered if life can be reduced to biology or even further down to chemistry. This sent many scientists looking for the answer and spawned the guiding question, could human life be artificially created at the cellular level? This would consist of arranging the correct amounts of various elements into the…

Introduction to Cell Biology – Unit 10193 – Chloe Barrett This essay discusses the difference in prokaryotic and eukaryotic cells, two types of specialised eukaryotic cell, and the relation of the structure of cell membranes to their function of moving substances in and out of cells. Prokaryotic and Eukaryotic cells are two very different, but also very similar cells. There are many differences between them that can help to associate between each one. Eukaryotes are any organism that…

Journal Article 2 Answers 1. The phenomenon of clonal selection and expansion occurs when T and B cells are activated by an invading pathogen. The leukocytes that have specific receptors for the pathogen are selected for and begin to divide via mitosis. The large number of cells that result from this expansion all have the same receptor for the pathogen that first activated the cells. Since these cells are specific for that pathogen, they are able to fight off the infection caused by the…

Current studies have found that taking omeprazole (prilosec) in combination with paclitaxel, will increase the effectiveness of paclitaxel as an anti-cancer agent. Paclitaxel is an effective form of cancer therapy that treats various kinds of cancer from ovarian to lung cancer. Paclitaxel works by promoting the polymerization of microtubules and prevents depolymerization to have a cytotoxic affect on cells (DeAngelis LM, et al., 1995). Omeprazole is a proton pump inhibitor used clinically for…
