this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was tested by having a chamber with quadrants that contain the culture‚ a hemacytometer‚ was used to carry out this experiment. After

Lab 1: Observation of Chemical Changes Name: Tyler Lee Lab Partners: none Date of Experiment: Feb 26 2015 Location: My House Course Number: CHE111 Abstract: The point of this lab was to test and observe chemical changes when mixing chemicals together and also through heating chemicals. Experiment and Observations: The experiment performed in the first part of this lab was to mix various chemical solutions together and then observe and record the chemical changes‚ also if a chemical

However‚ another colorant would be necessary‚ not blue but instead red or orange.

Seeds were surface- sterilized with 75% ethanol for 1 min‚ and then soaked in sodium hypochlorite (4% w/v Hi-media) for 10 min and rinsed seven times in deionized distilled water. The clean and sterilized seeds were inoculated on solid Murashige and Skoog (MS) medium in the dark. Seedling obtained was used

The objective of this experiment is to measure the rate of photosynthesis Hypothesis: The petri dish that is exposed to the most light and with the NaHCO3 solution will have the best results and the petri dish that is kept in the dark will have the poorest results. Material and Methods: 1. Get 4 deep petri dishes and label them 1‚ 2‚ 3‚ and 4. Fill dish 1 about 2/3 full with distilled water. Fill the other 3 about 2/3 full with 0.2% NaHCO3

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

Crystallization: Lab Report Theory/Introduction The purpose of this lab is to understand the concept of purification through crystallization. Crystallization is the process of purifying a substance‚ with the most adequate solvent. The process of crystallization came to be based on the principle of solubility. First‚ we must choose a solvent. The solvent is crucial to crystallization because it’s what will allow impurities to dissolve. Therefore‚ when selecting a solvent it is important that it
