Introduction: Kondashevkaya, M., & Diatroptov, M. (2013). Behavioural Characteristics of Ovariectomied Wistar Rats Trained in a Maze. Effect of Mental Stress and Castration for Infradian Rhythms. In Bulletin of Experimental Biology and Medicine (2nd ed., Vol. 155, pp. 241-246). Moscow: Springer Science Business Media New York. The purpose of this research was to determine if castrated rats are slower in locomotive activities compared to intact rats. Data from these kinds of experiments and research
Sexual sections is one of the processes of natural selection in which there is a competition for sexual reproduction, these competitions can be classified as intersexual or intrasexual. Intersexual competition occurs when one organism, usually female, chooses its partner. Intrasexual competition, on the other hand, happens when species from the same gender compete to sexually reproduce. The main purpose of this experiment is to understand sexual selection process and behavior of P. cinereus, a type
The use of preimplantation genetic diagnosis, used during in vitro fertilization, for medical screening and sex pre-selection is ethical so as long as it is done for the child’s best interest and not for superficial desires of the parents. Every year, around 3,945,875 babies are born in the United States (NIH, 2017). Unfortunately, 12.1% of women ages 15-44 and 8% of men ages 25 to 44 struggle with infertility issues (CDC, 2016). It is also challenging for gay and lesbian couples to become parents
Abortion on Demand Abortion on demand is the idea that women should be able to access abortion services at any point during pregnancy without having to undergo legal complications. There is a never ending debate on whether a fetus's personhood begins at conception or at the moment they are born. Depending on religion or specific beliefs the answer is always different. The argument on personhood may be infinite but the moment that life begins is not a question. Life is evident through the swift development
What is sexual selection? Sexual selection is the natural selection arising through preference by one sex for certain characteristics in individuals of the other sex. This means they are copulating with their other mate. Sexual selection can be dangerous in some cases depending on the rate and length of copulating. It can be so harmful to species that they may not be able to survive from it afterwards. Charles Darwin distinguished sexual selection and its various ways. He realized that sexual
Regardless of which side of the argument I would like to think is morally correct, one thing remains clear: as the technology of external wombs is getting closer and closer to becoming a reality, we as members of this society need to start asking ourselves some serious questions. Who is developing the technology? Who will benefit from it? Will external wombs liberate women from undergoing the difficulties of childbirth? I for one can see great points being made on both sides of the argument. One
Direct female-female competition is an important feature of woolly monkey reproductive biology. Direct competition regarding reproduction among males was minimal despite the fact that females mated with multiple males. Relationships with females were similar in the sense that they were generally tolerant but non-affilitive; females often directed harassment toward copulating pairs. Although there is a lot of long-term field research on the Lagothrix, there has been a lack of research specifically
Abortion is equivalent to the murder of a human being. The law states that purposely killing a human being is murder. The fetus is a human being and abortion terminates it, therefore abortion is murder. The United States legalized abortion in 1973. 45 years later and it continues to generate strong emotions as well as moral and legal controversy. I’m against abortion because it’s killing human beings that deserve to have a life. The baby should not suffer from the lack of responsibility and bad
Attention Grabber- Do you remember the first time you learned how to ride a bike or the first time you scored a 100% on a test? Do you remember the joy and the pride that came with this? Now think about the future. What do you want in life? Do you want a family of your own? Do you want a career instead of a job? What if these memories and future goals were impossible to have because someone stole it before you even had a grasp on it? Credibility- Background- An abortion is the intentional termination
The Reproductive System: The reproductive system of a male pig includes: the testis, the scrotum, seminiferous tubules, urethra, epididymis, and ductus deferentia. In a female pig, the reproductive consist of: oviducts, uterus, vagina, vaginal vestibule, and the oviduct. The reproductive systems are located between the hind legs in both male and female pigs. The Cardiovascular System: The cardiovascular system includes: the heart, thymus gland, coronary artery, septum, right and left atrium, pulmonary
