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

Procedures: The equipment that is needed to conduct this experiment is a 15x20 cm rectangle of Whatman No. 1 filter paper‚ an etherizer‚ ether‚ a vial of fruit flies‚ petri dishes‚ a razor blade‚ a glass rod‚ a dissecting microscope‚ a 1000 ml jar‚ aluminum foil‚ solvent‚ and a UV light. What needs to be done first in the experiment is that predictions need to be made on the effect of the enzyme mutations on the concentration

An agar plate is a Petri dish that contains a combination of agar and nutrients that help microorganisms grow. The proper method of setting microorganisms on an agar plate is know as “streaking”. In order to streak‚ the microorganisms are placed on a sterile swab or metal wire

A live counting usually takes a long time‚ because it requires the pre-identification of certain species in a living state under high magnification of a microscope. To prevent the fixative fluid from drying or crystallising‚ hold the concave slide in a Petri dish with moist filter paper on the bottom‚ or cover embryonic dish with a

University of the Philippines Los Banos BIOLOGICAL CONTROL Jeff C. Ebio G-1L INTRODUCTION Farmers sure aim to have abundant and healthy agricultural produce but that became so elusive as the prevalence of disease-causing fungi or bacteria and defective planting materials remain a challenge. To cease all these through a necessary and effective pest management and disease control schema must be utilized. Using chemical pesticide would be a usual resort though

Bacteria Purpose; the purpose of this lab was to see how much bacteria would grow on our variables we chose to use. Hypothesis; The dirtier the variable‚ the more bacteria will grow over time. Materials; 6 Petri dishes Cotton Swabs (Q-tips) Procedure; we started with 6 different Petri dishes that had a sticky yellow-ish substance layered on the bottom. Then‚ we picked out the variables we were going to use to rub onto the yellow substance. Lastly‚ we put soap on one Q-tip‚ rubbed a Q-tip on
