How can we explain the differences in achievement between boys and girls? Statistics show that it is clear that girls achieve more A* to C grades at GCSE then boys. This obviously shows that girls do better and achieve more in schools. In fact‚ since 1980 to the present day‚ the percentage of boys who have achieved these grades has risen. But so has the girls. When it comes to girls and boys choosing their options for GCSE‚ although they are open to pick the same subjects‚ there still seems to

Review Sheet Exercise 8 Chemical and Physical Processes of Digestion NAME Dane Wilson LAB DATE/TIME august 4th Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 7.0 because that is when the salivary is most effective and it breaks down carbohydrates. 2. How do you know that the amylase did not have any contaminating maltose

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

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

Explain how animals in art can reflect cultural values. Throughout the centuries‚ animals have appeared in works of art. The animals are often linked to cultural values. Cultural values are what is accepted or believed to be right in a culture. Cultural values differ between places and times‚ for example the Old Stone Age cave paintings at Lascaux in France(15 000-10 000 BC)‚ give us an insight into the importance of the animals to the existence of the people at that time. While in Surprise‚ painted

Livja Koka Anaerobic Bacteria In this experiment the purpose is to seek understanding between an organism and its use of oxygen. Oxygen is a very important part of the organisms’ survival. Oxygen has a tendency to form very reactive by-products inside a cell. These by-products create havoc by reacting with protein and DNA‚ thus inactivating them. Cells that are able to live in the presence of oxygen have evolved enzymes to cope with H2O2 and O2- and thus are not inhibited by O2. Also many anaerobes

species of bacteria look similar under the microscope and also have the same staining results (ex. Gram stain). To be able to differentiate between the different species‚ one can look at the metabolic differences (fermentation)‚ as well as the environmental condition differences (temperature‚ pH‚ oxygen requirements). Being able to manipulate these conditions in a controlled environment can help to correctly identify the exact bacteria. Different media can be used to culture and identify bacteria. Some

[Task 1]{M1} I am going to explain how different customers’ needs and expectations can differ. The supermarket industry provides a good example of the way in which different groups of customers will have different expectations and needs. Some customers just want to buy standard products at the lowest possible prices. They will therefore shop from supermarkets that offer the lowest prices and provide a reasonable range of products. In contrast‚ some customers are looking for variety and quality

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 after much
