• According to the Food and Agriculture organization: “Food safety is about handling, storing and preparing food to prevent infection and help to make sure that our food keeps enough nutrients for us to have a healthy diet” In other words, food safety is not just about eating balanced and healthy food, but it is about eating safe food and avoiding any kind of food borne diseases, most common: 1- Spongiform encephalopathies • Campylobacter • Escherichia coli infections • Salmonella • Shigella…

Introduction This practical consisted of using a microscope on two different types of samples, human hair and Lily pollen to acquire the basics of using a microscope. Three different types of objective lenses were used (4x, 10X and 40X). Furthermore it gave an insight to particulate matter in the air. Q1. Table 1 below shows the diameter of a human hair under previous stated objective lenses Standard deviation is used in this case to quantify the amount dispersal or variation in the results.…

shells together and is what actually manufactures them. Mussel shells consist of mainly calcium carbonate. To eat, mussels suck in water through their gills. The water brings oxygen and food into the mussel. Food is separated and taken to the palps then into the mouth. In females, gills also serve as an incubation chamber for baby mussels. Mussels also have a circulatory system powered by a two-chambered heart and a digestive system including: a stomach, intestines, and an anus. A nervous system…

resemblance to the foot of the other three classes. Instead, the Cephalopod foot bears arms and tentacles which offer jet propulsion. [4] To differentiate among the three remaining classes, Polyplacophora have dorsal plates, Bivalvia have a calcium carbonate two valve shell, and Gastropoda possess the distinctive characteristic of torsion, the ability of the internal organs to rotate 180° within the…

Stage one of production affects the quality of the raw cocaine paste made by farmers in the jungle mountain "pasta" labs. Paste purity content varies from farmer to farmer based on the recipe that they use, and whether they make it in pozo pits with acidic solutions or metal drums using gasoline and ammonia. Or whether they piss and shit in the paste which many do as a joke on Americans. With the 90's murder of Escobar, the cartel's power and the manufacturing process declined. The farmer's raw…

For this experiment, a group was employed by the Environmental Protection Agency as analytical chemists. Their goal was to identify an unknown compound that has been discovered in a landfill in their hometown. Once they identified the compound, they would then have to determine both the chemical and physical properties of the compound in order to inform the townspeople of any potential dangers. During the first week of lab, the group was given a small bottle containing an unknown white…

The creature that is being examined in this experiment is the now extinct Spinosaurus aegyptiacus, a dinosaur that lived in Northwestern Africa about 95 million years ago. The Spinosaurus (fig.1) was a creature that has been estimated to be anywhere from 13 to 18 meters (43 to 60) long, weighed 7 to 9 tonnes (8-10 tons), and is agreed to be by most paleontologists the largest carnivorous dinosaur of all time. It is thought to be a piscivore, although the Spinosaurus’ diet and lifestyle is very…

The Original System ( A Soccer Ball) Input, Output and the Process Input- Energy used to play with it. Output- Emotions and the ending conclusion of the game Process- The soccer ball is made in a sphere form and stitched with pvc (Poly Vinyl Carbonate) and/or leather for a great amount of exercise and resulting in a fun team sport. The ball rolls and usually stays on the ground. The Original System (A Soccer Ball) The impact of the soccer ball Impact on individuals - Soccer, The most popular…

follow steps 2 from previous part but however this time include the balloon in the mass of in the first column. 3) Weigh the vinegar, flask and a balloon and record the mass (M1). (ensure that the balance is reading 0) 4) Add 2.0 grams of sodium carbonate (M2) to the flask and quickly stretch the opening of the balloon over the neck of the flask to collect the gas as well as avoiding it from entering the atmosphere. 5) Finally record the final mass after the reaction and record it (M3) Results…

A macromolecule is a molecule that contains any "large number" of atoms. There are four main different categories of macromolecules that make up our body: carbohydrates, lipids, proteins, and nucleic acids. (1) Carbohydrates are sugars that store and transport energy. (2) Lipids also store energy and also are signalling molecules. (3) Proteins are linear chains of amino acids that help with the structure, function, and regulation of the body’s tissues and organs. (4) Finally, Nucleotides make up…
