Abstraction The intent of this probe is to find the frequence of meiotic divisions analyzed from intercrossed crossings collected from different strains of the fungus Sordaria fimicola. The experiment was conducted to show intercrossed crossings with MI and MII forms of ascospores within the asci. Over the class of seven yearss, the sample of Sordaria […]

Bottle Biology Project I made a two-layered bottle ecosystem. In the bottom layer, there is an aquatic ecosystem. In the aquatic ecosystem, there is one organism; a goldfish. In the top layer, there is a land ecosystem. There are many plants and other pudding flowers. This is a good example of two organisms from different […]

Obesity and Biology Obesity isn’t classified as an eating problem anymore. It is more than that a person’s biology plays a big roll. Cells and hormones play a big roll on how big you are and how your body regulates energy. Food equals energy and the body stores that energy in fat cells and uses […]

Introduction Osmosis is the movement of water molecules through a semipermeable membrane from low concentration to a high concentration. Research Question How does the concentration of salt (NaCl) affect the mass of a potato soaked in water (H2O) with different concentrations of NaCl over the course of 30 minutes? Hypothesis It is expected that the […]

CHAPTER I INTRODUCTION 1. 1 Background Food is one of human sources of calorie, protein, fats, and nutrition. Yet, because of the highly nutritious content, food is susceptible to growth of microorganisms. By the presence of microorganisms in food, the food is more likely to have shorter shelf life. Thus, mostly it is resolved by […]

BIOLOGY HSC NOTES MAINTAINING A BALANCE •Identify the role of enzymes in metabolism, describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions, such as metabolism. There activities can be catalytic (being able to control the rate […]
