Simone Biles’ decision to call her grandparents her own parents is her decision and hers alone. Society does not need to put their input on what she need and need not do. The decision Biles made to call them her parents is because they are the ones that played the parent role in her life. According to Erik Brady in USA Today‚ Simone Biles spent the first part of her life in foster

Anaerobic digestion Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen‚ used for industrial or domestic purposes to manage waste and/or to release energy. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide

Does the amount of time that orange juice is swished in a human mouth affect the pH of the saliva‚ which could inhibit the digestion of the starches in the orange juice? Hypothesis: The longer 2 mL of orange juice is held in a test subject’s mouth‚ the greater the ability of the test subject’s saliva will become to break down starches. Dependent Variable: pH of the saliva. Independent Variable: time that the juice is swished in the mouth. Controlled Variables: Orange juice only. The

Human Digestion Activity The digestive process involves the mixing of food‚ the movement of food through the digestive tract‚ and a chemical breakdown of large molecules of food into smaller molecules. The digestive system is made up of the digestive tract and other organs that aid in digestion. The digestive tract is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. Those twisted tubes include the mouth‚ esophagus‚ stomach‚ small and

Biology Digestion IA 13/03/2013 Jason Gao Rationale: Digestion is the chemical breakdown of food into smaller components that are more easily absorbed. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones. When food enters into stomach‚ gastric juice starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. The pH value of hydrochloric in the stomach

The chemical and mechanical processes of food breakdown are called digestion. (852-853) 3) The function of the hepatic portal circulation is to collect absorbed nutrients for metabolic processing and storage. (881) 4) When we ingest large molecules such as lipids‚ carbohydrates‚ and proteins‚ they must undergo catabolic reactions whereby enzymes split these molecules. This series of reactions is called chemical digestion. (854) 5) From the esophagus to the anal canal‚ the walls of every

Department of agriculture- digestive system of a cow‚ koala and dingo Digestion comparison Koala The Koala is the only mammal‚ other than the Greater Glider and Ringtail Possum‚ which can survive on a diet of eucalyptus leaves. Gum leaves contain only about 50% water‚ very little nitrogen‚ large amounts of fibre and potentially toxic oils. Koalas are found to have molars premolars to physically break down the food. Plants contain cellulose‚ which can only be broken down to release cell contents

Pancreatic cancer‚ a disease primarily affecting elderly on the range of 60 of age and above‚ has ranked as fourth causes of cancer-related death with the 5-year survival rate less than 5% in the United State. As reported by (Morana et al.‚ 2010)‚ the prevalence of tumors originated in the pancreatic head is 60%‚ 15% in the body while 5% of pancreatic tumors originate in the tail. The pancreatic ductal adenocarcinoma is the most common type of pancreatic cancer originating from the pancreatic head

Checkpoint: Human Digestion SCI/241 June 4‚ 2013 The path that food follows through the digestive system is very interesting. First you put the food to your mouth‚ take a bite‚ and chew. The salivary glands begin the digestive process at the sight and smell of food. After food enters the mouth and is moistened by saliva‚ it transforms into a bolus. Once the bolus leaves the mouth‚ it moves into the pharynx‚ where it can be swallowed. The bolus then moves from the pharynx to the stomach
