genes causing a defect are themselves substituted by correct genes in the patient to cure a disease" (Macer, 1990). Natural selection is the process in which organisms that are best adapted to their environment survive and therefor, reproduce more offspring. Darwin wrote, "natural selection is daily and hourly scrutinizing, throughout the world, the slightest variations; rejecting those that are bad, preserving and adding up all that are good" (Darwin, 1859). With the rise of gene therapy…

in nitrogen bases using a combination of A T C G. DNA is inherited from parents to offspring via chromosomes. DNA stands for deoxyribonucleic acid. DNA is shared throughout all living beings. Some have more nitrogen bases. Cellular DNA makes us who we are and determines our traits from our parents. All organisms share lots of the same DNA meaning that they are all related in some may. Embryos are unborn offspring in the process of development. If you could see yourself as a embryo you would…

People have existed on earth for billions of years. Many species of animals and fish that do not have males as a part of their community, but instead, they have the ability to reproduce asexually. Even though males are not necessary for survival, Matt Ridley argues using different business references and nature examples to prove men are similar to animals by nature because that is how women bred them to be. Ridley uses a different style of writing to further prove his point of the essay. The…

Does parental exposure to cocaine predispose offspring to develop a cocaine addiction? The effect of cocaine use on fetal development has been a hot topic since the drug reached the height of its popularity from the 1970s to the mid-1980s. A large number of research studies on the teratogenic effect of cocaine emerged in response to the so-called “crack baby epidemic.” The results of these studies were often exaggerated or flawed, reporting that populations exposed in utero would have severe…

show what constraints there are on breeding and population dynamics. This will be important to understand because for a population to grow or maintain stable levels environmental conditions need to be conducive to success in mating and producing an offspring that will go on to reproduce. This is crucial to conservation…

Case Study: Hereditary Canine Spinal Muscular Atrophy Genetic Background Hereditary canine spinal muscular atrophy (HCSMA) is proven to be an autosomal-dominate disease that affects most noticeably the Brittany spaniel (Pinter MJ, Waldeck RF, Wallace N, & Cork LC, Motor Unit Behavior in Canine Motor Neuron Disease, 1995). HCSMA originated as a spontaneous mutation in the Survivor Motor Neutron gene found in the purebred Brittany spaniel population (Ericsson. A & Rubin. C, 2012). Due to the…

Emerging from the Dark Ages (1100-776 BCE) in Greece, the polis was a city that created a complex and sophisticated civilization based on the political institution and philosophical resolution (Mathisen 2012, 167). Two of the most powerful city states in Greece during the time of the Classical Age (500-387 BCE) were Spartans and Athenians, conflicting with one another during their highest point in their own civilizations. Neither Sparta nor Athens were considered the ideal polis because both…

Flowers, produce by the sporophyte, function in sexual reproduction The four floral organs are sepals, petals, stamens, and carpel. Sepals protect the floral bud. Petals help attract pollinators. Stamens bear anthers in which haploid microspores develop into pollen grains containing male gametophytes. Carpel contains ovules (immature seeds) in their swollen bases. Within the ovules, embryos sacs (female’s gametophytes) develop from megaspore. Pollination which precedes fertilization is the…

that they were inferior to the human race. The Nazis made Germans believe that Disabled Germans were inferior to the master race. They also made the Germans believe that people with disabilities or criminal minds reproduce faster, and that the offspring of the disabled would also have mental and physical disabilities.…

6.1 Case study There are two classifications of costs associated with construction projects, direct costs and indirect costs. Direct costs include the labor, material and equipment operating costs necessary to put work in place. Indirect costs include supervision, job and home office overhead, profit, financing, and the cost of inflation. Direct costs can be allocated to each activity on the project. Indirect costs, on the other hand, cannot be realistically prorated and assigned to each…
