ntroduction In this experiment we created standards to be able to compare a mystery substance off of. We were tasked to investigate a murder that took place by analyzing a man’s last meal to find out where he had ate based on the content of his stomach. Before we could test the mystery substance we had to establish standards‚ so we could compare off of them. Based on the results of this lab‚ we believed that the victim last ate at Buffalo Wild Wings (Veliz). Methods and Materials We started this

Chlorella pyrenoidosa is a widely available microalga with several commercial applications for food and nutritional purposes. It has also revealed great potential as future industrial bioenergy producer due to its robustness‚ high growth rate‚ and high carbohydrate and lipid contents‚ and can be cultured under autotrophic‚ heterotrophic and mixotrophic conditions. However‚ in presence of organic carbon sources‚ it produces higher biomass with better carbohydrate contents than its autotrophic

HOMEOSTASIS Homeostasis is an internal environment that is regulated in order to remain in a stable and constant state. To be able to maintain homeostasis‚ the homeostatic control system shows how communication within the body is important in homeostasis‚ there are four main components to this system: the stimulus (change)‚ the receptor (detects the change)‚ the control centre (receives the information) and the effector ( produces the response). The stimulus in this case would be the change in

All living things require the input of energy to exist – this energy is used to drive the thousands of biochemical reactions that occur to allow the organism to grow‚ reproduce and sustain life. This energy comes almost always from the Sun‚ in the rst instance – energy from sunlight is captured by photosynthetic organisms (e.g. plants‚ algae‚ certain bacteria) and converted into carbohydrates. These are then broken down by a process called cellular respiration‚ to produce energy-rich molecules (e

The most common organic molecules are carbohydrates‚ lipids‚ and proteins. Carbohydrates contain carbon‚ hydrogen and oxygen with a ratio of 1:2:1‚ this means that for every 2 hydrogen atoms there is one carbon atom and one oxygen atom. They are necessary for the body to function properly because they provide the fuel that burns to produce energy. Carbohydrates come in the class of either a monosaccharide‚ disaccharide‚ or polysaccharide. Monosaccharides are the simplest form of a carbohydrate‚ disaccharides

Nutrition is the process of consuming‚ absorbing‚ and using nutrients needed by the body for growth‚ development‚ and the maintenance of life; nutrients are chemical substances in foods that nourish the body. Many nutrients can be synthesized in the body’. Those that cannot be synthesized in the body called essential nutrients-must be consumed in the diet. They include amino acids (in proteins)‚ certain fatty acids (in fats and oils)‚ minerals‚ and vitamins. Nine of the 20 amino acids in proteins

The levels of organization for an organism are: atoms‚ molecules‚ cell‚ tissue‚ organ‚ organ system‚ organisms‚ population‚ community‚ ecosystems‚ and biosphere 3. The characteristics of living organisms are; a. Life is organized b. Life uses materials and energy c. Life reproduces d. Life is homeostatic 4. The major driving force behind evolution is; natural selection (brings about adaptation

food we eat has to be broken down into nutrients that can be absorbed by the body‚ which is why it takes hours to fully digest food. In humans‚ protein must be broken down into amino acids‚ starches into simple sugars‚ and fats into fatty acids and glycerol. The water in our food and drink is also absorbed into the bloodstream to provide the body with the fluid it needs. Insulin : nsulin is a hormone and is found in even
