Characteristics can help to classify organisms apart. I.e. we can tell that a mammal (human)‚ a fish is different by seeing that fishes live in water‚ humans live on land. Fishes breathe underwater by their gills while the mammals (humans) breathe oxygen with their lungs. Another example could be how reptiles and birds are different‚ the most obvious is where the birds have feathers and reptiles have rough skin with no feathers. The last example is where the amphibians are cold-blooded‚ lay eggs

Discuss the role of negative feedback in living organisms and how it benefits these living organisms? (25 marks) Negative feedback is the process by which changes occur to bring an organism’s internal environment back to the normal level. One example of negative feedback in a living organism is the ways humans regulate their blood glucose levels. I will firstly discuss the processes that occur as a result of blood glucose levels being too low. When blood glucose levels are too low the pancreas

Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater

How Organism Learn: Classical and Operant Conditioning There are two main explanations of how organisms learn. The first explanation is known as classical conditioning. The second explanation is known as operant conditioning. These two types of learning are exhibited in our everyday lives through our home‚ school‚ and school. Classical conditioning was discovered by Iran Petrovich Pavlov. He was originally a physiologist whose main focus was the digestive system (Gazzaniga 230).

with changes that occur in environmental temperature‚ wavelength of light‚ and light intensity. Using a photosynthetic organism of your choice‚ choose only ONE of the three variables (temperature‚ wavelength of light‚ or light intensity) and for this variable. • Design a scientific experiment to determine the effect of the variable on the rate of photosynthesis for the organism • Explain how you would measure the rate of photosynthesis in your experiment • Describe the results you would

My Organism Physiology Paper NA May 21‚ 2015 BIO/101 My Organism Physiology Paper As of today‚ there are so many organisms throughout this world that has survive the adapting to ever-changing environments. Organisms are living things such as animals‚ a plant or humans that can function on our own. Organisms are parts of the body that works together to help the numerous processes of life. It is very important for a living organism to adapt to the world and the changing around them

by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic pathway such as photosynthesis suggest common ancestry? 4. Describe the basic structure and function of a chloroplast. 5. Describe the benefit of

Wheat 10 Rice 9 Baker’s Yeast (Fungus) 11 Candida Yeast (Fungus) 13 Neurospora (Fungus) 14 When scientist say that all living organisms share a universal genetic code it means DNA is called the universal genetic code because the structure and components of DNA are that all living organisms are related in some type of way. The universal genetic code relates to the hypotheses of life on earth by showing life originated from a single ancestor‚ the genetic code

Ng Boon Yee/ Group B06/ A0099215Y Comparison of Organisms from the Class Oligochaeta and Class Chilopoda Animal phylogeny is an interesting and rapidly changing field of study. To date‚ there are about 1.5 to 1.8 million species of animals that have been named and described by biologist with 15‚000 to 20‚000 new species named each year. However‚ millions more species are yet to be discovered and classified. Taxonomists have divided the animal kingdom into about 35 phyla (Solomon et al.‚ 2011). Out
