Conclusion

The eggs were different from one another. Some were softer and had a more bouncy feeling to them, while others were hard. This can become a problem in the observations and in the size and mass increase. Some of the egg shells were not completely eroded by the acid. This could have resulted in different masses, and might have let in more or less water. Improving: To control the amount of solution in each beaker, it should be measured. There should be enough to top the egg by about 1-2 cm to ensure we can see if it floats or sinks. The eggs should be made sure to be about the same softness. This ensures more accurate numbers, mass, and size changes. The eggs should be left in acid until the shell is completely eroded. This ensures there is no more shell that could change the mass and size changes. ?? ?? ?? ?? May 27th, 2009 ...read more.

    Second, the photometer and branch were attached to the clamp stand and the plant was left to rest for 10 minutes. To the same clamp stand the sensors of humidity and temperature were attached in order to control the controlled variables.

  2. Bio lab - Oxygen Consumption in germinating and non-germinating seeds

    Germinating seeds process faster cellular respiration than non-germinating seeds because germinating seeds contain embryos that grow and process mitosis quickly. Although non-germinating seeds also have alive embryos, they are dormant. Since embryos of the non-germinating seeds are dormant, they do not require lots of energy to process mitosis.

    - ERRORS: - One possible weakness in the method of this activity is the way in which the camera was used to take images for future use. However using a camera, we are unable to see the details of each section of the quadrat and able to clearly distinguish...which may have altered greatly the population count, and thus the diversity.
