How does Absence of Food Affect Time Crickets Spend Resting? Samer Aldaher BIO 2490 Behavior Section Dr. David Gilley INTRODUCTION: What happens to crickets in phases of food insufficiency? In particular‚ how does their resting behavior change‚ if it even changes at all? The reason behind this study was to find out whether crickets applied their resting behavior as a means to survive or conserve energy in times of “famine”‚ if you will. During the preliminary time spent noting and describing

proteins. The results showed that that myosin light chain was not present. It was concluded that the cells were not differentiated enough to begin with‚ the amount of cells used was not sufficient and the differentiation media did not have a neutral pH at the time of harvest. Introduction The purpose of the experiment was to differentiate C2C12 cells into muscle cells and tests for presence of muscle protein specifics. The hypothesis was that proliferating C2C12 cells could be induced to differentiate

DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

molecules together (Caroline Ritchie‚ 2013. This process is called hydrolysis and is catalysed by protease. The three main protease enzymes produced during digestion are pepsin trypsin and cymotrypsin. Pepsin is released into the stomach and begins digestion by breaking down proteins into smaller molecules called peptides. Trypsin and cymotrypsin are released into the intestines completing protein digestion.There are fourmajor
