Michele Green #3 Manuscript Questions 463 Reproduction 4/28/17 Efficacy of embryo transfer in lactating dairy cows during summer using fresh or vitrified embryos produced in vitro with sex-sorted semen 1) What is the question the authors are trying to answer? - The authors are trying to determine the difference of transferring fresh embryos or vitrified embryos that were made by in vitro with semen that was sorted compared to artificial insemination to see which one improves calving rates as well as pregnancy in lactating dairy cows during the summer. 2) What is the hypothesis of the study? - The hypothesis of this study is that in lactating dairy cows, their fertility increases during the warm summer months or in other words, they have heat stress, when using the embryo transfer method. 3) Provide a brief description of the study design. -…

The main purpose in life is to reproduce offspring that will carry on your history after you pass away. Reproduction occurs when a male and female get intimate with each other. The only way that could happen is if they really prefer each other. Preferences for sexual reproduction started with Darwin when he proposed “sexual selection” rather than natural selection (Buss and Barnes, 1986). This occurred when Darwin saw an evolutionary change in peacocks that was not for survival, but to attract…

Reproduction In this essay I will attempt to explain the key events in human reproduction and explain the male and female reproductive systems. Both males and females require fully functioning reproductive systems in order to conceive naturally, I will first begin by explaining the male reproductive system, the testes are cradled within a ‘bag’ of skin called the scrotum, their two functions are to produce sperm cells and sex hormones. Next, the vas deferens. Sperm passes through the vas…

Asexual reproduction is a reproduction process with only one parent that ends with identical animal cells. The purpose of asexual reproduction is to reproduce with wasting less energy. Sexual reproduction is a reproduction process with two parents that ends up with unidentical animal cells. Sexual reproduction is used to reproduce and make a unique being. The animal I am focusing on is the red kangaroo. The red kangaroo uses sexual reproduction. This chosen type of reproduction is a good choice…

a) Human reproductive cloning / Reproduction One of two reasons for human cloning is reproduction. It`s prime objective is to produce children for couples who are unable to conceive. There are 2 ways in which this is possible. The first is a transfer of an adult nucleus into ovum. This results in an identical person yet; the mitochondrial DNA differs. The second method is by splitting the embryo, similar to the natural process that occurs in twins. This process also results in an identical…

process. Some cultures place emphasis on having a boy, some expect you to have multiple children, and then, depending what country you live in, if you can’t have kids then you are out of luck because they don’t have the necessary medical practices which means the hope of having a family of your own is slim. Once you have the children, a whole new set of rules and expectations come into play that even further complicates the idea that you raise a child and ship them off. To truly understand…

that it had made our lives exceptionally easier. This being said, it has also come with a profound cost. Walter Benjamin in his essay “The Work of Art in Mechanical Reproduction” discusses photography’s impact on our cultural perceptions of art. He argues that photography lacks essential characteristics of more established forms of creative visual representation which is otherwise known as aura. With this there is a substantial shift for Benjamin between what is art in…

Cultural Reproduction Knowledge is transmitted to the children through the structured and designed curriculum, which could be either in the form of hidden or overt curriculum. I agree with the author and Bernstein (1977) on the issue of reproduction of inequality that” social inequalities originate in class based differences in family structures and linguistic codes and these differences are further reinforced by the schools”. The working class children are familiar with certain linguistic…

I wanted to do this essay on all drugs and the different effects they have on reproduction but it ended up being a very broad topic. I am in no way shape or form involved with marijuana nor do I support it for recreational use. Many states are beginning to legalize marijuana for recreational use and more states are starting to push laws for marijuana to be legal in their state. With all these changes in laws these days as males and females we need to understand if what we do as “kids” or…

Having no real introduction and analysis of feminist theory prior to taking SWMS 301 class, apart from agreeing about the unfairness of unequal pay based on gender and complaints about female objectification by male population, I have not really stopped to consider how women are really perceived in this society. One of the topics I would like to discuss is the role and portrayal of women in the media. After reading Susan Bordo’s article, The Body and Reproduction of Femininity, my attention has…
