Lab Explained: Effect of Salinity on Seed Germination

Research Question How does salinity affect the seed germination of Solanum lycopersicum? Introduction Relevance to Real world Covering 14% of Australia and home to over two million people, the Murray Darling Basin is Australia’s largest and most iconic river systems (figure 1) (McCormick, 2015). As over one third of Australia’s food supply is produced by…

Essay: Embryonic DNA Reconfiguration via CRISPR

Just weeks ago on September 28th, Japan’s governmental health and science ministries officially drafted national guidelines on human gene-editing and manipulation experiments, particularly within embryos (Cyranoski, 2018). Before then, Japan’s stance on genetic experiments had remained neutral. Now it is joining an increasing list of countries who support this genetic innovation.             One of the…

Essay: Are Genetic Privacy Laws Necessary?

Genetic Privacy laws exists to prevent the abuse of genetic information. It is understood that these laws were created specifically to prohibit health insurance companies, employers and housing agencies from using genetic data to discriminate against citizens.  Genetic discrimination can be described as the unfair treatment of individuals by employers/insurance companies based on gene mutations…

Lab Report: The impacts of salinity on modern agriculture

1.0 Background: A breakthrough scientific experiment conducted by ‘Carnegie Science’ found that soil salinity considerably affects the growth rate in plants.  The experiment found how plants create Abscisic Acid as a stress hormone when the endodermis is exposed to drought or saline environments. “The endodermis also acts as a guard, with Abscisic Acid, to prevent…

Lab: Carbon dioxide production by yeasts under different temperatures

Problem: Yeasts undergo aerobic cell respiration if there is sufficient oxygen and releases carbon dioxide as a waste product. Yeasts, like any other cells, have an optimum temperature at which they work most efficiently, including the process of cell respiration. This experiment aims to discover the relation between temperature and the carbon dioxide yield of…
