Reproduction

Reproduction. The underlying goal for every single organism on earth. All creatures, large and small, have their own way of producing offspring. Many bacteria and plants produce asexually, which means they do not require a sexual partner in order to reproduce. For many other creatures such as reptiles, amphibians, mammals, and many other creatures, A sexual partner is required. Each type of organism has there own way to attract mates. Birds like turkeys fane out their tails to impress…

Final Project - Philosophy of Christian Education The Christian worldview of Christian education is the total involvement of Christian education to bring about the change in the moral standard of norms in society. The participation of individuals working alongside the government to help shape a better more productive society. This involvement means participating in the mainstream of government function. This could mean as employee, voter participation, volunteering for campaigning for…

 Parent of a murderous offspring loses because instead of six grand offspring, it has just the five as a result of the successful siblicial offspring’s reproduction is an example of parent-offspring conflict.  Parent-offspring conflict is a concept developed by Bob Trivers after he realized that some actions can advance the fitness of an offspring while reducing the reproductive success of its parent.  Parent-offspring…

Males Compete, Females Choose: Evidence in Humans In non-human animals, it is typically males that engage in intrasexual competition, and females that exercise intersexual choice. This is apparent in the morphological and behavioural differences between the sexes. Trivers (1972) argues that this is so due to differential investment in offspring between the sexes, which makes access to females a limiting resource in males' reproductive success. In other words, males compete, females choose. In…

Sociobiology is defined as the way in which human biology affects how we orchestrate our culture. It can affect how we interact with people and how we mate, both when and why. Sociobiology explains both logically and rationally why all cultures exemplify the same human sexual behavior. This being that men are encouraged to partake in sexual relations with multiple different partners, while females are discouraged from having coitus outside of marriage, and are even sometimes shunned. It is a…

reproductive systems. Wood had studied gynecological medicine at Melbourne University in Australia. He also conducted research in London and the U.S. He invented the method of using frozen embryos and also pioneered the use of fertility drugs for the reproduction of multiple eggs, which increases the success rate in IVF pregnancy. He also made other major contributions to the medical field of gynecology with research involving fetal monitoring, psychosocial obstetrics, uterine contractibility,…

informed of the risk of multiple births prior to the entering treatment. Financial incentives and improved success rates drives the practice of implanting multiple embryos (Asch & Marmor, 2008). The risk of multiple births is 11.2% for each assisted reproduction therapy (ART). The goal is a single viable pregnancy. To achieve a successful outcome, selective termination of embryos may be required. An informed consent for IVF should include all possible outcomes including the risk of multiple…

Vertebrate Histology (BIOLOGY 364) Fall 2015 Lecture Final (Take-home) A. Pick 3 of the following and argue that the following are either “adaptive” or necessary for survival, homeostasis, and/or reproduction: 1. Adluminal compartment of seminiferous tubules • The adluminal compartment is made up of spermatocytes, spermatozoa and spermatids. The compartment is considered a tight-junction. This tight-junction is said to be a blood-testicle-barrier. This means the…

(Abell et al., 2013). Similarly, fish have developed numerous social, reproductive, and predatory behaviours that allow them to adapt to various conditions. For example, observing reproductive behaviours of hermaphroditic reef fishes found that reproduction was species dependant, though there were similarities and overlaps (Petersen, 1987). Studying Serranus faciatus, they found that individuals has fully function gonads of both sexes (simultaneous hermaphrodite) however, the larger individuals…

Contrast and Comparison between Frog and Songbird Mating Calls By the law of the nature, most creatures seek to survive and reproduce. In other words, they reproduce to survive or to keep their species on living. In this research paper, I would compare and contrast the advertisement calls for mating between frogs and songbirds and talk about how the production of mating calls is related to Tinbergen’s four questions. Both anurans and passerines have calls. Also, males usually produce the mating…
