The Impact of External Factors: Water and the Carbon Dioxide on the Rate of Photosynthesis

1. Research question Due to the fact that most plants have no appropriate apparatus to ingest and digest food, they have to obtain it by themselves using simple ingredients. That…

Oxygen Consumption in Germinating and Non-Germinating Seeds

Purpose: To find out and compare the cellular respiration rate at different temperature by using germinating and non-germinating pea seeds. Hypothesis: If the germinating peas are in the cold or…

Germination Lab Experiment

Introduction In this experiment we will be focusing on the factors, which influence the process of germination of a plant. Germination is the process when a seed sprouts from dormancy….

Investigating the Effect of pH of Hydrogen Peroxide Upon the Activity of Catalase

Variables involved: Different pH levels will affect the Catalase enzyme by determining whether the enzyme activity will increase, decrease or if it will denature altogether, so the pH level of…

The Effect Of Exercise On Cellular Respiration

Introduction: Cellular respiration is the process that cells use to break down glucose; this releases energy that is used to produce ATP. Cellular respiration involves a series of enzyme-catalysed reactions….

What is the Amount of DNA Extracted from Different Fruits?

Hypothesis: The DNA extracted from the strawberry will be the greatest amount due to their softness and pulverization. They have large genomes being an octoploid. This means that they have…

To Investigate How Aerobic Exercise Affects the Heart Rate

To investigate how aerobic exercise affects the heart rate of a 16 year old male. The aerobic exercise I will be using to conduct this experiment is jumping jacks, commonly…
