Ch. 1: Biology: Exploring Life 1) Slides 1 and 2: What is the main difference between physiological adaptation (as in sense‚ respond and adapt to the environment) and evolutionary adaptation? Evolutionary adaptation occurs over generations. Evolutionary adaptation does involve genetic change but it’s the change in traits as a result of genetic change that drives natural selection and evolutionary adaptation (just genetic change alone won’t drive evolutionary change). Physiological adaptation is

The degradation of cholesterol by Pseudomonas sp. NCIB 10590 under aerobic conditions. 1. R W Owen‚ 2. A N Mason and 3. R F Bilton ABSTRACT The metabolic pathway of cholesterol degradation by bacteria has not been completely established. Several possible intermediates have not been identified and many pathway delineations have not involved the use of the cholesterol molecule per se and just one bacterial species. The bacterial degradation of cholesterol by Pseudomonas sp. NCIB

Biological Science Lesson 1 Zoology - branch of biology that deals with the life of animals. 1. Morphology - studies forms and structure of animals. a. Gross anatomy - performs surgical technique ; dissection (cutting up). b. Paleontology - studies pre-historic forms of animals through fossil. 2. Histology - study of tissues & organs‚ their structure‚ functions & composition at a microscopic level. 3. Cytology - study of the structure & function and its parts at microsopic level or
