germination of radish seeds between Eucalyptus‚ Lemon‚ and a control. Methods The method used for this experiment was very easy to set up. Five different lab groups performed the same experiment. Three petri dishes is the first thing I needed. I placed a piece of paper at the bottom of each dish and found the exact center and made a mark. Next I put ten radish

done by spreading bacteria on a culture plate and starting a new stock of bacteria from a single colony. Fours characteristics by which colonies can be identified are shape‚ color‚ size and texture. 4-A Petri dish is used as a container for a medium used to grow cultures. Leaving the Petri dish open will increase the probability that your culture will be contaminated. 5- Between each set of streaks you sterilize the inoculating loop in the Bunsen flame. At the beginning of the next streak you

“The assumption that animals are without rights and the illusion that our treatment of them has no of them has no moral significance is a positively outrageous example of Western crudity and barbarity. Universal compassion is the only guarantee of morality”. (Arthur Schopenhauer‚ the Basis of Morality). Although animal testing has contributed too many life saving cures and treatments‚ it is cruel and most experiments involving animals are flawed. In my opinion testing of these products should be

offspring. If a male and hermaphrodite reproduce‚ then there is a 50% chance it will be either a herm. or a male. All in all‚ it is more likely to find more hermaphrodites in a petri dish‚ like shown in class‚ because they can reproduce with themselves and don’t need to look for another person. In the first petri dish‚ we discovered that there was a larger amount of hermaphrodites than males‚ which makes total since from the information said above. Below is a graph showing a male and a herm
