    woman‚ taking the eggs and joining them with the man’s sperm in a petri dish. After a couple of days the resulting of an embryo occurs‚ which leads to implantation into the woman’s uterus. Zygote intrafallopian tube transfer (ZIFT) and gamete intrafallopian tube (GIFT) are similar to IVF‚ except the sperm and eggs are placed straight into the fallopian tubes. Other technologies are also being used to reproduce children scientifically‚ for instance the freezing of eggs. Freezing eggs has been a controversial

    To determine the percentage by mass of Calcium carbonate in an egg shell Aim: is to find and work out the percentage of calcium carbonate by mass in eggshells by using acid base “back titration” Introduction: Calcium Carbonate‚ CaCO₃‚ is a compound which is polymorphic and therefore means that it can be found in a variety of different objects or organisms. For example: Rocks (limestone‚calcite)‚ sea snail shells‚ Eggshells‚ pearls and many more. This investigation will focus on finding out the

    Osmosis is the diffusion of free water molecules from a region of high concentration to a region of low concentration across a partially permeable membrane. Osmosis is complete when all of the water molecules have been evenly spread out and can take place either in plant cells or animal cells‚ so long as a partially permeable membrane is present. Osmosis can also be conducted in the visking tubing experiment‚ where the visking tubing is an artificial permeable membrane. So how does Osmosis take place

    Experiment for the measurement of carbon dioxide and oxygen concentrations and their functions during the act of breathing. Introduction: Humans‚ like all living organisms need‚ O2 in order to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces

    VII. Conclusion The hypothesis that if a potato is placed in a tube with different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass

    An investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions
