JEBA INBARASU Organism Physiology is the method in which many diverse living organisms are considered to have developed from earlier forms during the history of the earth that can be defined as Evolution. Several organisms have evolved as a result of environmental changes within their habitats. Example is a diagram of a whale and details about how the whale has evolved physiologically and has become adapted to fit the environment

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

Distinguish between the strategies used 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

THE VICTORIA SCHOOL SANTIAGO JACOME LAB REPORT PTC BIOLOGY SL AIM: The aim of this lab is to analyze the genotype differences of classmates that are able to taste PTC‚ Thiourea and Sodium benzoate and determine the phenotypes found. Testing the ability to taste PTC has been a mainstay activity in human genetics for generations of teacher and students. The ability to taste PTC is inherited. Traditionally this is presented as a case of simple Mendelian inheritance involving a dominant allele for tasting

Today prejudice issues have improved a lot since 1930’s‚ this has only been the case for 30 or 40 years. But they are still little problems such as the Ku Klux Klan. This is a secret organization founded in the southern states during Reconstruction to terrorize and intimidate former slaves and prevent them from voting or holding public office.

In its life and reproduction‚ every organism is shaped by‚ and in turn shapes‚ its environment. Ecological scientists study organism-environment interactions

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).
