difference in Daphnia’s response when exposed to red light compared to white light. Thus‚ the null hypothesis was rejected and the experimental hypothesis was accepted. These findings could be due to the negative phototactic response that occurs when they are exposed to visible light that are above 600 Mn (nanometers) that are also considered the color red. This shows that Daphnia have a greater phototactic reaction to red light than when exposed to white light. When compared to a similar study‚ the same

Maria Xena M. Montalbo Year III – St. Albert A. Problem/Objective The study’s objective is to apply radish extract as an alternative pesticide. Specifically the study aims to determine the effectiveness of radish extract in exterminating household’s pests such as ants. Furthermore‚ the study aims to create the most effective radish extract solution in terminating pests. B. Application The study’s product aims to be applied as a pesticide. It tends to provide an alternative for the current

needs to be able to live is seeds. Seeds provide a food source that is not from meat and herbivores are able to survive. Different seeds can from both plants‚ and fruits. When plants want to reproduce the plants make seeds that can be dispersed by air‚ water‚ or animals and the seeds that survive find a place in the ground to start grow. For some plants‚ the seeds are in protective shelling like fruits and pinecones. This extra protection layer is there to allow the seeds to make it new ground by animals

number of paper towels throughout the experiment. Most of the seeds had germinated in the paper towels. The one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My hypothesis was‚ if I increase the amount of paper towels

Science Lab Report Conclusion Ms. Seaward Jeneé S. White May 16‚ 2015 How Light Refracts Throughout Water My experimental question for my project is: Would light bend at a refractive angle after it propagates through water? The resolution to my experimental question is that light does bend at a refractive angle after it propagates through water. My hypothesis for my project is: I hypothesize that light will bend because of real world examples and experiments. One instance is light refracts

Yeast Mutations due to Ultra-Violet Light Exposure Summary: Mutations have played one of the most important roles throughout life on Earth. Without genetic mutations there would not be the diversity of living species that we see today. Understanding how mutations work and how they are created is an important step in controlling and isolating genes for experimentation. In this experiment we tested the effects of Ultra-Violet light on growing single-celled yeast. We did this by first creating serial

The compound light magnifying instrument‚ which will be utilized as a part of this lab movement‚ is an instrument with two focal points and different handles to center the picture. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives:

Results The above results show the data collected after a week of measuring the biggest plant per bag. Each day the biggest radish plant in site A was measured and by day five the largest plant was 5 centimeters long‚ and had developed small green leaves. By the 5th day site B and D’s seeds showed no signs of growing and length remained at 0 centimeters. Site C and D’s superior seed both grew a total of 3 centimeters according to the 5th day measurements. Both the graph and table display the same results
