This was controlled by adding a sufficient amount of distilled water to each condition, so the volume stays consistent. The temperature must be controlled because it can affect the rate of reaction, if the temperature increases then the rate of reaction would also increase. To make sure that the temperature is consistent in each condition, this experiment was conducted in one period of time in the same room. Lastly, the size of the beaker needs to be the same because reactions in smaller beakers may occur more quickly than those in bigger beakers because there is more pressure. Therefore, when doing this experiment, the sizes of the beakers were the same.
Consequently, these molecules are able to move faster and the probability of collusion with other molecules is increased. Hence, the time taken for the reaction to be completed is reduced and the rate of reaction increases. Conclusion The experiment was conducted with the aim of being able to determine the activation energy of the reaction. Additionally, the effect of temperature on the rate of reaction was also to be
As a final result, more reaction will be catalyzed and more oxygen gas will be produced; therefore, enzyme activity and reaction rate will increase. As stated before, the optimum temperature for enzyme activity is about 35-50 degrees Celsius. The line on the Graph 1 has a steep slope after it peaks because the enzyme denatures when the temperature increasing to
This increase in length occurs due to an increase in the fusion of shorter microridges, which can be accounted for by the increased crosslinking of actin by the higher levels of phosphomyosin that are localized to the apical domain. Thus, the has mutants have a less fragmented and precociously stable microridge pattern.8 . Therefore, to understand the role of microridge dynamics in allowing the epidermis to sustain the increased mechanical stress, I will knockdown aPKC in zebrafish embryos using morpholinos that competitively block translation14. I will subject these embryos to mechanical stress using the oil injection paradigm. when the epithelial tissue is subjected to mechanical stretch by oil injection in the hind-brain ventricle, the area that the tissue has to cover significantly increases.
Once this is done, object 1 may be removed and replaced with the rubber stopper having more mass than the first one. (object 2) Note that, because the width of the stopper is more it will require more string to go through the holes and tie it. Using a metric ruler re-adjust the radius, ensuring that it the exact same radius as the first, 18.9cm. Make sure all the safety procedures are followed, then begin your experiment Hold the tube and swing the stopper in a circular motion ( refer to image 2 ) Try using the same amount of force to move the object in circular motion as with the first object. Do this, while also making sure that stopper ( object 2 ) is being swung in circular motion across a horizontal plane Record the time it takes for the stopper ( object 2 ) to complete 20 revolutions Repeat this five times and record all the observations in the second data table Replace object 2 with the rubber stopper having most mass, this will be object 3.
Kinetic energy is energy that exists due to the movement of particles. As the temperature of the sugar increases, the kinetic energy also increases as the particles are moving faster at higher temperatures. Sugar dissolves better in water of higher temperatures as it takes less time for it to dissolve. The reason for this has to do with increased the increased molecular motion that is
Looking into what other stress’s that could be added to shift the equilibrium constants. Seeing what happens when you add these stress’s, like if there is any way that you could add pressure, change the concentration more, or dilute the product which could be something that could be added on to the
However, when this liquid to the reservoir, it contains a higher ratio of the more volatile substance than it did originally. This is repeated numerous times in the fractional distillation column and each time the liquid vapourizes, the vapour increases in purity. Eventually, the vapour contains only the most volatile substance and it is condensed and
Oiling them twice a week will keep them nourished and smooth. Combing or brushing them will be easier and will not cause hair breakage. Natural oils from olive, coconut, mustard seeds and other herbs provide hair with the necessary supplements. They repair the damaged cells on the hair and restore the lost protein. Oiling not only provides the hair with essential nutrients, but the process enhances blood flow to the hair.
