Asexual reproduction

Recent technological advances in biology have prompted me to want to study the subject as an undergraduate. I have been drawn to how the world works and what everything is made up of since secondary school, but in recent months my focus has shifted specifically towards the study of genetics. A wide and varied subject, ranging from eugenics and the ethical considerations of genetically engineering organisms, and to the more recent scientific breakthroughs in said area of study, the study of…

organelle. Bacteria can be rod, sphered or spiral shaped. Bacteria are the most plentiful organism on Earth; as well as being the most various. Humans and plants could not survive without bacteria. Reproduction in the form of binary fission is how bacteria procreates. This is an asexual form of reproduction where the cell divides into two identical cells. Mutation is also known to happen. This occurs when bacterial cells…

dispersed by animals, water and wind and will re-grow elsewhere when winter is past. Seed, stems and tubers are also often spread by gardeners dumping garden wastes in bush land where the weed can reproduce vegetatively. Vegetative is a form of asexual reproduction in plants. It is a process by which new organisms arise without production of seeds or spores…

For example, a lab test involving the reduction of pigment production in a culture can show if an isolate of C. parasitica is infected with CHV-1 (16). In the field, infection of CHV-1 in the fungus decreases canker growth and both sexual and asexual reproduction of C. parasitica (16). In many other plant pathogens, virus purification and antiserum production have contributed heavily in understanding and detecting pathogens, even in some mycoviruses (7). Though generally these methods are not…

The development of biotechnology for pesticide resistance is projected to play a critical role in the agricultural industry for its potential benefits in cell and tissue culture and genetic and biochemical techniques, though minimally used today. The most common role of biotechnology thus far has been the circumnavigation of resistance to herbicides, but remains to be applied to fungicides, insecticides and rodenticides. The latest biotechnology is being developed in its techniques for…

and therapeutic cloning and what are the ethical issues associated with it? Cloning occurs naturally in nature. We can see this in some plants and single celled organisms, like bacteria, which produce genetically identical offspring through asexual reproduction. Ideas of artificial cloning have been around since 1938 when Hans Spermann proposed his "fantastic experiment" to grow an embryo from an egg with a nucleus obtained from another cell. Cloning has come a very long way since then: from…

refers to having low same-sex attraction and low opposite-sex attraction. Most individuals have no preference if any and may still pursue relationships. This does not confirm the notion, lack of attraction to people imply a lack of sex drive. Those of asexual orientation have a libido, they simply just don’t experience sexual attraction. Asexuality is an orientation about attraction, not action as are the other sexual…

and therefore, left a very undetermined fossil record. The vertebrate fossil record begins approximately 400 million years ago. Early Chordates were tunicates, marine organisms that would frequently form large colonies through asexual reproduction, a process of reproduction where an organism does not need a partner in order to achieve fertilization. Eventually, lancelets evolved from tunicates with a more developed brain, along with gills that opened…

This essay will be discussing the four domains of feminist disability theory, which are; representation, body, identity and activism. This essay will discuss the feminist responses to these specific four issues with supporting quotes and evidence from the reading and an article in attempt to define concepts, to critically interrogate them and highlight hoe these issues are framed in feminist though and activism. Representation of feminism and disability has in many cases been catagorised as one…

11) Compare and contrast the processes of mitosis and meiosis. Your answer should not only include a summary of each process, but should discuss both the similarities and differences between them. Mitosis is an asexual process that results in identical offspring. There is no crossing over or homologous pairs in this process. There is only one division in this process and two diploid cells are formed at the end of it. It results in two daughter cells with the same number of chromosomes. Mitosis…
