homeostasis and sports - experiments measuring the effects of exercise on the body

Aim To Investigate the effect of the game squash on the blood glucose level. Hypothesis - blood glucose level is usually affected by an activity or exertion such as a sport. Squash is a very exerting game and so a lot of glucose is required in providing energy while playing the game. The result is that the blood glucose shall fall. However homeostasis involves positive feedback and negative feedback. In this case , after a fall in the blood glucose level, positive feedback shall work to regulate the blood glucose level , by breaking down glycogen in the liver to glucose. Therefore the original glucose level shall be attained. However blood glucose level can also be influenced by the type of food that an individual has taken preceding the test.this then determines whether positive feedback or negative feedback shall occur Apparatus * A Glucometer kit * Squash rackets * Squash balls * Dettol * Cotton wool * Stopwatch Procedure . samples of blood of 2 volunteers were obtained using a sterilised lancets 2. The blood sample of an individual was then placed on the film that was provided by the glucometer kit 3. The film was inserted in the glucometer slot and the blood glucose level value was read off the screen and recorded 4. step 2 and 3 were repeated for the second volunteer 5. Afterwards, the game squash was started, and immediately the stopwatch too 6.

Aquaponics is basically the combination of aquaculture (raising fish in a tank) and hydroponics (cultivating plants in water). It can be used in the farming industry as farmers use it to farm at a large scale (acres). Also people harvest a vast amount of edible fish from this closed ecosystem. With that in mind, we would grow fish and plants together in one integrated system and test the chemistry of the water in relation to different elements present in the system, such as: Ammonia, nitrites, and nitrates in a nitrogen cycle. Then we would investigate the biological impact on the

Determine the presence of reducing sugar, protein and starch in the food products by using Benedict test, Biuret test and Iodine test,

Chapter 1 – Chemistry of Life Determining the Presence of Certain Nutrients Kieun Bae, DP2 - Biology HL Introduction The idea of this experiment was to plan the diet for a day and determine if the diet plan contains the necessary nutrients, by testing the food products with chemicals. In this way, we would have better idea about what kind of food product should be included in the daily diet. The meal-plan of the day we have made was following: . Breakfast . milk 2. cereal . Lunch . bread 2. juice 3. cheese 4. apple . Dinner . pasta 2. lattice 3. meat 4. tomato 5. yogurt 6. red wine 7. onion This was planned by discussing the actual food products we commonly take in a day. There are few diary products that are commonly known to contain a lot of protein, necessary carbohydrates for each meal (bread, pasta and cereal) as well as the vegetables that contain many various healthy nutrients including glucose (simple sugar), vitamins, minerals etc. Also, there is meat that is supposed to contain some fatty substances and protein. The essential nutrients that we need daily for our body to function properly are mainly six. They are water, carbohydrates (glucose, starch, sucrose etc.), proteins, fats, vitamins and minerals.[1] In the lab, we are going to find out the presence of different nutrients and decide whether the planned list of daily diet food products

Ecosystems: Photosynthesis

Photosynthesis (explained) One of the most common producers is green plants. These organisms absorb light energy from the sun or chemical reactions to convert carbon dioxide to organic matter. Green plants can also use water to convert carbon dioxide to organic compounds such as sugar glucose. The result of this is that it releases oxygen as a by-product. This process driven by light energy is photosynthesis. Using the method of photosynthesis, plants are able to create every complex organic molecule which form their body by using mineral nutrients such as sulphur, phosphorus, potassium and nitrogen which can be retrieved from either soil or water. A green pigment called chlorophyll is one of the molecules that are used to absorb light energy in photosynthesis. It is obvious to be able to identify which plants photosynthesise by looking at they're colour. If it is green, then it photosynthesises. Some examples of these types of plants include the beach grass, shrubs, and maritime forest plants found on Plum Island. There is a huge range of plants that can photosynthesise, whether it be microscopic bacteria or extremely large trees. In every ecosystem, there are always active producers that photosynthesise. AIM The aim of this experiment will be to test the rate of photosynthesis using Gardenia Augusta Magnifica in a warmer environment against a cooler

IB SCIENCE GROUP 4 PROJECT GLOBAL WARMING Does acid rain cause hardness in water? Does carbon dioxide affect plant growth? Is there a difference between the convection current of acid rain and distilled water? Ali Ercingöz Burcu Erdogan Deniz Kiratlioglu Can Atalay Ege Zorlu Arman Onart Subjects and Group Members Chemistry: (Ali Ercingöz, Can Atalay) Does acid rain cause hardness in water? Biology: (Burcu Erdogan, Ali Ercingöz, Ege Zorlu) Does carbon dioxide affect plant growth? Physics: (Can Atalay, Deniz Kiratlioglu, Arman Onart) Is there a difference between the convection current of acid rain and distilled water? GLOBAL WARMING Global warming is the effect of greenhouse gases on the earth. Greenhouse gases are the emissions that rise into the atmosphere and trap the sun's energy, keeping the heat from escaping. Because of the global warming, the air temperature near the earth's surface rose by 0.9ºC during the last 100 years. This causes the sea levels to rise, increase the intensity of extreme weather events and increases the amount of acid rain. As a result of these newly formed conditions, unprecedented natural disasters and damages the natural life such as agricultural yields, species, extinctions and the range of disease vectors arise. While these are occurring, people are trying to defend their future both socially
