How to Tell a Male From a Female Shark

Ever wondered how to tell the sex of a shark? Distinguishing the sex of a shark is easier than in most marine species. Its all in the sharks external anatomy. Male sharks have modified pelvic fins called claspers. Females do not have these claspers. As male sharks age, the calcium is deposited in the claspers, so that older males have harder claspers. In addition to the absence of claspers, females tend to be larger than males, although those differences may not always be obvious, especially in the wild. Where Claspers Are Located These claspers are located on the sharks underside, within the sharks two pelvic fins. They look kind of like long fingers that extend underneath the sharks belly.   Shark Reproduction in Brief The claspers are used for reproduction. Sharks breed via sexual reproduction with internal fertilization. This involves the sharks usually positioning themselves belly to belly, a process that can involve a lot of biting. The claspers have grooves which are used to transfer sperm from the male shark to the females cloaca.  The sperm is moved through the grooves using seawater. The sperm fertilizes the females eggs, and voila!—a shark embryo is created. From there, development and birth vary by species.   In some species, such as bamboo sharks, the female lays eggs outside of her body (oviparous). About 40% of the 400 shark species lay eggs. In ovoviviparous  sharks, such as whale sharks, basking sharks, and thresher sharks, the eggs develop inside the females body, but the young are born live. Placental viviparous sharks give birth in a way similar to mammals—the young shark is nourished inside the female by a yolk-sac placenta, before being born live. Bull sharks, lemon sharks, and hammerhead sharks are examples of species that employ this strategy.

Success And Effectiveness Of Zuckerberg - 1588 Words

Success and Effectiveness In just the eleven years since Facebook’s launch, Mark Zuckerberg has become one of the most successful and influential people in the world. The social network started as a side project that Zuckerberg would work on in his dormitory room. Now, Facebook is more than merely a social network; it is a publicly traded technology powerhouse that has changed the way people around the globe communicates, and the company continues to innovate and expand their horizons. A world without Facebook is hard to fathom, and it doesn’t seem like they are going to be disappearing anytime soon. Zuckerberg is just 30 years old with a net worth of $32.9 billion, making him the second youngest self made billionaire in the world.†¦show more content†¦In 2009, Vanity Fair ranked Zuckerberg as 23rd on their Top 100 â€Å"Most Influential People of the Information Age†. The following year, he received the top spot, and was also sixteenth in New Statement’s survey of t he world’s 50 most influential figures. In 2010, Zuckerberg was also named Time Magazine’s Person of the Year, and has been a part of the piece for the past five years, recognizing him as one of the 100 wealthiest and influential people in the world. The film The Social Network came out to depict the story of Facebook’s origins and gave more insight about who Mark Zuckerberg was. The Jerusalem Post named him the most influential Jew in the world in both 2011 and 2013. Facebook Achievements Perhaps one of the most telltale indicators of the power and influence Facebook would eventually have over the world was in 2006, when a company, Student Monitor, conducted a survey on college students. According to the survey, Facebook was tied with beer as the second most popular thing among undergraduates, only behind the iPod. Since 2008 when they dethroned Myspace, Facebook has been the leading social networking site based on monthly unique visitors. However, the social network had been getting recognition even before such an exciting feat. PC Magazine put Facebook in their 2007 â€Å"Top 100 Classic Websites†. They also won the Weebly’s â€Å"People’s Voice Award† in 2008. Each year from 2008-2010, the company won Crunchie’s â€Å"Best Overall Startup or Product†.

Project Management Performance and Report †MyAssignmenthelp.com

Question: Discuss about the Project Management Performance and Report. Answer: Introduction The essay reflects on the aspect of information requirement in a project for developing information system within an organization. According to Walker (2015), the project generally requires a series of activities that are associated with gathering, analyzing, utilizing as well as tracking various information of the project. The assignment illustrates the various requirements as well as importance of information in the project. The paper also elaborates risks due to inadequate information and various mitigation strategies for resolving the issues, which are associated with the development of the Information System. Information needed for implementing the project The project Implementation of information System requires appropriate information about the various activities of the project, budget, time-period, software requirements and about the implementation procedure of the information system. The project managers must have proper information about the project budget as well as time (Meredith, Mantel and Shafer 2013).They must have specific knowledge about the organizational feasibility, economic feasibility, technical feasibility, operational feasibility as well as schedule feasibility. Information about various activities of the project including, initiation phase, planning phase, development phase, implementation as well as closure phase is needed for completing the various tasks of the project that are related with the development of information system successfully (Mir and Pinnington 2014). The project managers must have specific knowledge about the risks that are associated with the project so that they can be handled properly. Proper information about the resources is quite important for completing the entire project within a specified time as well as budget. The information that are gathered as well as utilized helps in completing the entire project within the specified time as well as budget. It is analyzed that proper software requirement specification helps in illustrating how the information system will work from the perspective of the user. Technical specifications are also necessary for elaborating the internal implementation of the software. It helps in providing proper knowledge about the data structures, models of relational database, choice of various programming protocols as well as various environmental properties (Sears et al. 2015). One of the key advantages of gathering software requirement is streamlining different procedures of development. The project manager assigns different roles as well as responsibilities to the stakeholders of the project by utilizing the information about the capabilities as well as project requirements. Information about risk must be gathered as well as utilized for managing the risk appropriate ly so that it does not create any problem associated with the project (Hwang and Ng 2013).Feasibility of the project is also significant as it helps in analyzing the success of the project. The information that are gathered or used assists the project managers to complete the various tasks that are associated with the development of Information system as per the schedule. Proper schedule must be followed for developing the information system appropriately within the specified time as well as budget. Problems due to inadequate information The development of information system in an organization requires appropriate information for completing the entire development of the project within the estimated time as well as budget. There are number of problems that generally arises is due to improper information gathering or due to inadequate information (Schwalbe 2015). If the project managers does not have proper as well as effective information about the budget as well as time estimation then they will face number of problems in completing the entire project successfully within the estimated time as well as budget. It is analyzed that the development of information system have number of challenges which must be mitigated properly, therefore inadequate information about various risks obstruct the development of the project (Turner 2014). It is identified that appropriate information about various requirements of the project including both the software as well as hardware requirements which are important for developing the pr oject properly as per the project schedule. The project managers must have proper information about the various resources that includes staffs, budget as well as project requirements so that they can handle the project effectively without facing any problem (Martinelli and Milosevic 2016). Inadequate information leads to improper management of project that further creates number of issues related with the development of the project, its operation as well as management. Mitigation strategies for resolving problems of inadequate information It is analyzed that the development of information system in an organization requires appropriate amount of information for managing the development of the project effectively but if the information are not proper, then the project can face numerous challenges which must be mitigated properly as well as effectively (Walker 2015). Proper communication within the various stakeholders of the organization is considered as one of the significant strategy that helps in resolving the issues associated with it. Communication between different stakeholders helps in providing information reliably as well as adequately so that the project can be developed properly without any problem. A project manager in the organization with good communication skill can be able to motivate the employees towards the project (Martinelli and Milosevic 2016). This trait is also helps in assigning various roles as well as responsibilities to the employees as per their capabilities so that the development of inform ation system can be managed significantly as per the schedule. It is analyzed that proper documentation can also be a mitigation factor. Proper documentation must be provided to the various stakeholders as it helps in providing an overview about the project in context to project planning, monitoring as well as organization for completing the development of the project successfully. Conclusion It can be concluded from the overall assignment that proper information is one of the significant need for completing the development of the project within the specified time as well as budget. It is analyzed that it not only helps in managing the project successfully but also assist in monitoring, controlling, planning as well as organizing project successfully. It is analyzed that inadequate information for a project implementation raises number of risks which must be managed properly or must be mitigated by utilizing proper strategies. It is analyzed that proper communication is considered as one of the factor that helps in resolving the issues associated with the development of Information system.
