The hypothesis made prior to the experiment was not correct - the distilled water did result in the most weight gain (g); however‚ the 5% salt concentration did not result in the least weight gain (g). Table 1 clearly highlights that the 3% salt concentration resulted in the least weight gain (g). The distilled water resulted in the most weight gain (g) because the solution is hypotonic – a hypotonic solution results in the water diffusing into the cell because the molecules of the substance are

Gender Specific Toys Affect on Children Enrolled in Preschool Versus Children Not Attending Preschool Gender plays an important role in the way children are raised in today’s society. The common stereotype that feminine toys are for girls and masculine toys are for boys is prevalent‚ even with all of the political advancements our society has made to try to free the world from these stigmas. It starts as early as when a child is in the mother’s womb. Most women will celebrate the arrival of

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then

Does Gender Affect Color Preference? Abstract The objective of this experiment was to determine if gender plays a role in color preference. In other words‚ do males actually prefer blue and green‚ while females favor pink or purple? This experiment was conducted by surveying ninety-six people‚ 48 males and 48 females‚ to complete a short survey. The survey asked them if they were color blind and whether they were male or female. They were then given five color cards (blue

The Aim of this practical was to observe what effect temperature had on the permeability of the cell membrane. Introduction Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane)‚ however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability of the cell membranes (i.e. Tonoplast)
