The species to be further researched on is the Giraffe. ‘Darwinism’ and ‘Lamarckism’ are the two main theories focused on throughout the analysis, both will be investigated to determine the comparisons and differences towards the evolutionary process of a Giraffes life. Jean Baptiste Lamarck, best recognised for his theory of inheritance and acquired characteristics, supposed that if an organism changes in life in order to adapt to its environment, those changes are passed on to its offspring. He said that the change is made by what the organisms what or need, therefore body parts used often would grow and change to help with the survival of the animal, and result in the offspring inheriting similar characteristic, however if the body part was not used Lamarck believed it would gradually disappear and not be inherited by offspring (Abbott,2001). On the other hand Charles Darwin’s evolutionary belief was that organisms, even of the same species, are all different and that those which happen to have variations that help them to survive in their environment survive and have more offspring, these offspring are born with their parents ‘helpfulShow MoreRelatedConceptual Foundations Of Social Research Methods Essay1262 Words   |  6 Pageswh ere did the concept and ideology of positivism was first formulated?

Also the independent variables that were measured were the resulting color of the Benedicts reagent, the Sudan IV and the color of the Beirut reagent. The relationship was the between the food samples and the reagents to identify the three major types of macromolecules. . ) d. ) The most difficult test to conduct for this experiment was the test in step 3. It was hard to determine whether the food samples contained lipids by observing whether or not they made the brown paper turn translucent because some of the samples were solid, therefore they did not absorb into the paper. For example, when the banana and oat samples were lifted up and put into the light, the banana and oats just fell off of the paper due to the f act that they did not secrete any liquid. E. In the lab when baking soda is referred to as negative control, it means that baking soda was used to check for contamination of the reagent so that it wouldnt give a false positive.

The primary use for BAH is as an antioxidant and preservative in food, food packaging, animal feed, cosmetics, rubber, and petroleum products. BAH also is commonly used in medicines, such as jettisoning,alleviation, and sanitation, among others. BAH has been added to edible fats and fat-containing foods for its antioxidant properties as it prevents food from becoming rancid and developing objectionable odors. BAH side effects means it also cause allergies, affect the brain, alter behavior, and may even cause cancer. BAH is an oxidant which can form cancer-causing compounds in the human body. Butyrate hydroxylation (BATH), also known as photoluminescence, is a allophonic(fat- soluble) organic compound, chemically a derivative of phenol, that is useful or its antioxidant properties. BATH is advocated as a diet supplement and antiviral useful against herpes family viruses. It is listed for use in foodstuffs like mixed nuts, margarine, chewing gum and enriched rice and frozen breaded shrimp.
