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

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

Structure and function of macromolecules within a living organism ‘Some biological molecules in organisms are small and simple containing only one or a few functional groups‚ others are large‚ complex assemblies called macromolecules’ [1]. The term macromolecule is convenient because the bulk properties of a macromolecule differ from those of smaller molecules. These large chemical compounds have a high molecular weight consisting of a number of structural units linked together by covalent

ABSTRACT The exercise was about the techniques in proper sectioning of plant tissues and staining techniques so that the study of plant structure will be easier. In free hand sectioning‚ the plant organ must be 45° upright and is held between the thumb and the base of the forefinger. A razor blade was used to cut the plant thinly in cross sections. Obliquely cut tissue is a big mistake since the surface of the tissue will not be even upon viewing under the microscope. Iodine-Potassium-Iodide

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
